Editorial.

El Encuentro de Investigación de la Asociación Colombiana de Facultades de Odontología, es un espacio que congrega a los investigadores del gremio odontológico y de otras disciplinas, a compartir los adelantos científicos y tecnológicos que a nivel nacional e internacional se han desarrollado en el campo de la salud oral y de su relación con la salud general.

La facultad de Odontología de la Universidad CES de Medellín es en esta ocasión, la institución responsable de congregar, analizar, retroalimentar y promover el desarrollo investigativo de todos las personas que participan en este evento; por tanto, es importante resaltar todos los esfuerzos y el interés de las personas de esta institución, que integran el área administrativa, académica y particularmente de aquellas que lideraron la organización de este evento y que hace posible que podamos congregarnos, dialogar y aprender.

La investigación como herramienta del desarrollo, solo tiene valor en la medida que permite la interacción activa y el aprendizaje significativo, y es por esto que el Encuentro de la ACFO adquiere un valor agregado; pues reúne a investigadores nacionales e internacionales para que todos aprendamos de todos y en especial la importancia de reconocer la dinámica del desarrollo del conocimiento en el campo de la odontología.

Es grato darle la bienvenida a una nueva facultad de odontología, Institución Universitaria Colegios de Colombia sede Cali, que se integra a las veinte y una ya asociadas. Cada una de estas facultades, registra una historia y una dinámica propia en el campo de la investigación y es precisamente la oportunidad de compartir estas experiencias, lo que ha permitido a todas crecer, siempre fundamentadas en el respeto a nuestras diferencias.

El Encuentro de Investigación es también un espacio para que los jóvenes investigadores compartan sus experiencias en el marco del IV Encuentro de Semilleros de Investigación de la red SIF-ACFO, es justo además, reconocer los esfuerzos de la delegada de investigación de la Fundación Universitaria San Martín, para que el trabajo de los semilleros rinda un fruto y fortalezca la acción en red de estos nuevos “Gestores del Conocimiento”.

El III Encuentro de la Asociación Internacional de Investigación dental (IADR) es una actividad que también se desarrolla en el marco del evento, como una acción particular que busca promover el reconocimiento de la investigación que se realiza a nivel nacional, en el ámbito internacional.

La ACFO y en particular la División de Investigación hacen un reconocimiento especial a la empresa Colgate, pues gracias a sus aportes hace posible la realización de este evento y permiten evidenciar como el apoyo de la empresa privada es fundamental en el desarrollo de la investigación odontológica en Colombia y a Nivel Latinoamericano.

En este XIX Encuentro Nacional y V Internacional de investigación Odontológica se presentan 110 trabajos en las áreas de ciencias básicas, pedagogía, endodoncia, periodoncia, ortodoncia, crecimiento y desarrollo, medicina bucal, epidemiología y otras; por lo cual se puede afirmar que este espacio es una de las mejores oportunidades para agrupar a los profesionales de todas las especialidades de la odontología que quieren conocer, fundamentado en la evidencia, que hay nuevo, que ha cambiado y que permanece en el campo de la salud oral. Sean todas y todos bienvenidos.

2Abstract

Key Words: Dental Pulp, IL-6, IL-8, Inflammation, Glass ionomer, Citotoxity

Objectives: To determine the presence of proinflammatory cytokines IL-6 and IL-8 in human dental pulps exposed to the treatment with glass ionomer as an intermediate base. Materials and methods: Random controlled blind clinical trial in 22 extracted teeth from 11 patients of the Graduate Orthodontics and Orthopaedics Clinic. Inclusion criteria: subjects between 14 and 25 years old, with healthy premolar teeth, closed apexes, who needed exodontias for orthodontic purposes. Systemically compromised patients were excluded. The variables were interleukin release values, exposure to treatment with glass ionomer. 11 teeth in the experimental group and 11 in the control group were randomly assigned; The presence of interleukins was observed by means of flow cytometry with specific fluorochrome-marked isotypes; The Statistical

Analysis was carried out by means of Student's T test for paired data, p≤0.05, harmony correlation coefficient. Results: In the 22 pulps it was seen on average greater release of IL- in cases (59.6%), and in controls (57.4%). IL-8 in cases (2.9%) and in controls (3.7%). There are no statistically significant differences between the groups. The application of glass ionomer as an intermediate base didn't increase the presence of cytokines. There was a correlation in IL-6 between the case and the control (r=0.90). Conclusions: It was observed in the 22 pulps under study, that there are no statistically significant differences between the evaluated groups. There was a higher IL-6 release, which was not increased by the glass ionomer application as an intermediate base.

Abstract

Key Words: Resistance, mercury, amalgam, saliva, antibiotics, anaerobics

There can be at the most a 50% mercury presence, in amalgam fillings, circulating in the oral cavity for a long time, which makes it possible for bacterial flora to become resistant to this heavy metal. This being a very controversial hypothesis. The resistance will probably be valid for antibiotics as well. There are anti-microbial resistant genes that can link together and against selective pressure multiple resistances can be generated. This study explores the relation between anaerobic bacterial resistance to antibiotics and mercury present in the oral cavity of volunteers (19-56 years old) with ± 5 years of amalgam restorations, scheduled at the Faculty of Dentistry of the University of Cartagena, Colombia. The restorations were planted in culture media, and in anaerobic conditions the isolated microorganisms were identified, determining its antibiotic susceptibility and its resistance to mercury (MIC according to report by Nakahara (1977); Cervantes Vega (1987); Vaca (1995) for aerobic bacteria, making the modifications for anaerobic bacteria according to Derren et al., 2003 and Pike et al., 2002)

Twenty-five anaerobic stubs were isolated: Staphylococcus saccharolyticus (6), Peptostreptococcus anaerobius (6), Eubacterium lentum (1), Leptotrichia bucalis (2), Actinomyces viscosus (1), Peptostreptococcus prevotii (1), Gemella Morbillorum (1), Peptostreptococcus tetradius (2), Eubacterium limosum (1), Lactobacillus sp (3), Propionibacterium granulosum (1). Which resistance oscillated between 10,5%, 73,60%, 100% and 89,5% for the antibiotics clindamycine, oxaciline, trimethoprime and tetracycline respectively. The bacterial resistance to mercury chloride was 100%. The amalgams extracted from normal individuals have high mercury

levels (≥1ppm), and the bacteria in oral cavities have high resistance to mercury and antibiotics.

4Abstract

Key Words: Dental pulp, stem cells, mesenchyme, tissue regeneration, Cell Culture, Flow Cytometry.

There is little known about the cell precursor responsible for reparative dentine formation in adults. It has been propose that postnatal stem cells from human dental pulp exist and that their source is pulpar tissue. Stem cells can be identified and isolated from a mixed population of cells, by means of flow cytometry to detect CD73+ and CD105+ markers and the absence of CD34, CD45, in healthy human dental pulp. Objective: To evaluate the expression of CD/73 + / CD105 + / CD34-/CD45- in samples of healthy human dental pulp. Methods: Four primary cultures were done from human dental pulp of healthy adults and the expression of markers was evaluated by flow Cytometry. Results: The primary cultures consisted dental-pulp cells with morphology similar to fibroblast. Preliminary results suggest that there is a small percentage of cells CD73 + / CD105 + in the healthy pulp tissue that have been identified as specific antigens for Mesenchymal cell progenitors and negative for CD34 and CD45, common markers for hematopoietic and endothelial cells.

3Abstract

Key Words: Detection, anaerobics, periodontitis, culture, PCR, bacterium-specific indicators.

Molecular and culture research has shown that the microbiota associated with primary endodontical infections is represented mainly by anaerobic bacteria. Some of them regarded as etiologic agents of periapical diseases are difficult to cultivate and characterize, which is why this project used cultivation methods and molecular testing as PCR, which is a promising alternative. This study included root canal samples taken with paper cones from 11 patients, transported in pre-reduced thioglycolate broth. These samples were grown in Agar blood and chocolate in anaerobic conditions, obtaining Peptostreptococcus prevotii (9.1%), Peptostreptococcus micros (27.3%), Veionella spp (9.1%), Actinomyces (9.1%), and Bacteroides ureolyticus (18.1%). It is interesting to see the presence of Capnocytophaga spp (27.3% in this study) reported so infrequently in endodontical lesions. The polymerase chain reaction (PCR), using bacteria-specific indicators, was used to detect bacteria in the samples. Positive results were obtained in 8 of them, including number 6 who did not report culture growth, which showed a correlation between culture and PCR of 90.9%.

5Abstract

Key Words: Rat embryos, whole mount in situ hybridization, expression of genes

Introduction: Tooth development results from the interaction between ectodermal and mesenquimal tissues, by means of reiterative and sequential expression of molecular signaling families which induce differentiation of the tissues and cells involved, producing changes that will finally determine the formation of the dental organ. Whole tooth regeneration tissue engineering experiments have used mouse ectodermal embryonic tissues to initiate tooth development when recombined with non dental mesenquime. Using rat embryos would imply advantages for these experiments but no information is available about the developmental stages at which expression of initiation signals occur in this species. Objective: Evaluate expression of ectodermal signals Pitx2, Shh, and Wnt10a, originating in oral embryonic tissues of Lewis rats, at different developmental intervals (E11.5, E12, E12.5, E13) to used them in tissue engineering experiments. Methods: A Lewis rat colony was established, and pregnant females at different embryonic developmental stages (E11.5, E12, E12.5, E13) were sacrificed by CO2 asphyxiation followed by cervical dislocation. The collected embryos were treated by whole mount in situ hybridization to evaluate expression of Pitx2, Shh y Wnt10a.Results: Between E12.5 and E13 Pitx2, Shh and Wnt10a expression is mostly restricted to the ectoderm covering the stomodeum first branchial arch's maxillary and mandibular process of Lewis rats embryos. At this stage Shh is expressed in the PAZ on both upper and lower extremities. Conclusion: Embryonic oral ectoderm (E12.5-E13) expresses two of the three tooth initiation signals (Pitx2 and Wnt10a) evaluated and thus is considered competent to induce mesenquimal differentiation towards the tooth linage in whole tooth regeneration experiments.

Abstract

Introduction: The salivary -amylase is the most abundant enzyme in saliva, among its main biological functions, it links with great affinity to dental surfaces and different oral microorganisms and it is responsible for the initial break down of starches in the mouth.Objective: To determine the concentration of total proteins and salivary -amylase in children, and related to the dental cavity index.Methods: 100 children were classified according to the cavity diagnostic index, obtained from a clinical examination. They were classified within 4 of the seven categories of the ICDAS index: healthy, white opacity, micro cavity and extensive cavity. Saliva samples were obtained to measure the total protein concentration by means of Bradford method and also the salivary -amylase concentration by means of Elisa test.Results: The total protein results were analyzed by means of Stata. It was found that comparing the total protein concentration medians within the four study groups, there were not significant statistical differences. The salivary -amylase concentration median in three of the four groups:healthy, micro cavity and white opacity showed no significant statistical difference, although the healthy group is 20% higher than the other two. In the extensive cavity group, this value is lower, showing significant differences between this group and the other three.Conclusion: The lower -amylase concentration within the extensive cavity group could be indicating that the functional redundancy in this enzyme, being the most important, is the one related to the oral surfaces protection.

8Abstract

Key Words: Streptococcus mutans, propolis, Minimun bactericidal concentration (MBC), Minimun bacteriostatic concentration (MBsC)

It was evaluated the antimicrobial activity of four propolis extracts from Argentina, five from Colombia and one from Cuba, using Streptococcus mutans ATCC 25175. The samples were kept in a 96% ethylic alcohol solution, remaining a concentration of 3%. The bactericidal and bacteriostatic activity was measured by the minimun inhibitory concentration (MIC) among a range of 0.02 and 15mg/ml. All of the analyzed samples showed activity against Streptococcus Mutans when they are used to concentrations 15 a 3.75 mg/ml.

The propolis that presented the highest effect bactericidal (MBC) was number 2 and 3 (sample from Colombia) after 48 hours of incubation. The highest effect bacteriostatic was presented by the sample 2 (propolis from Colombia) after 24 hours of incubation. 70% of the propóleo samples increased their activity after a time of incubation of 48 hours compare to the effect shown to the 24 hours. All the Colombian samples showed a superior effect, when the bacteria were exposed to the propóleo for a longer period of time; in two of these cases until of five dilutions, samples 2 and 3, this effect was presented in a moderate way, using the argentine samples 6 and 10 while the other samples (30%) remained steady.

7Abstract

Key Words: Antimicrobial activity, dental caries, S. mutans, Isertia laevis

The fact of recognizing to S. mutans as the most important microorganism in the initiation of the dental caries, drives to design measures to the elimination or decrease of this one in oral cavity. In addition, with the high index of resistance to the antibiotics, there exists a considerable interest to study the effects of natural compounds obtained of floors on microorganisms of importance in oral cavity. Isertia, genus of the family Rubiaceae, is distributed from Central America up to the north of South America; in Colombia there are known seven species of this genus distributed in different regions of the country. The aims of this study were to evaluate the activity antimicrobial of extracts, fractions and subfractions obtained from leaves of Isertia laevis on 18 bacterial strains belonging to the genus Streptococcus, Lactobacillus and Actinomyces associated with the dental caries and with other oral pathology. The extracts, fractions and subfractions were obtained from dry leaves of Isertia laevis. The antimicrobial evaluation was realized in agreement to the method of agar diffusion in well against the following bacteria: S. mutans ATCC 25175, S. mutans ATCC 31989, S. mitis 804 NCTC 3165, S. salivarus NCTC 8606, S. mutans 10923, L. acidophilus 903 ATCC 4365, S. sobrinus, S. rattus FA 1 (G), S. mutans C67-1, S. cricetus AHT, S. mutans ingbritt, L. plantarum 748, L. casei 475, L. brevis, A. odontolitycus, S. mutans 35FS3, S. mutans 35FS1 and S. mutans 29FS2. The obtained extract in ethanol and the fraction MeOH: H20 showed inhibitory activity to 20 and 10 mg on all the strains. From the fraction in MeOH: H20 different subfractions were obtained. The subfraction 9 was the most active to concentrations of 50 and 35 ug for well on 18 microorganisms included in the study. Up to the moment, I. laevis had not been an object of chemical study not microbiologically, for what it represents, in agreement to the obtained results, a promissory source in which they must follow studying the antimicrobial effects in models more nearby to the infectious event in vivo and the targets of action.

Abstract

Key Words: dental alterations, anodontia, crowding, cleft lip and palate

Objective: to determine the dental alterations and the prevalence of cavities in children 3 to 14 years old with fissured lip and cleft palate of Dental Foundation in Santiago de Cali 2007. Materials and methods: A cross sectional descriptive study was conducted on a studied population of 30 children between 3 to 14 years old with fissured lip and cleft palate who attended the Operation Smile Foundation. The gathering of information was done by a survey and a clinical exam analyzing dental cavities, dental alterations and in addition to this a plaque index, using the Simplified Oral Hygiene Index (OHI-S). Results: it was found that a 100% of the population presented dental alterations, crowding (70%) and anodontia (63.3%) being the most frequent ones. As for dental cavities, there was a 90% frequency among the population presenting at least a lesion. Conclusions: The population presented dental alterations of size, form and number; crowding had the higher proportion, in the masculine sex and the temporary teething. Dental cavity was present in most of the children, under the bacterial plaque index; this can be explained by the high percentages of hypoplasia and crowding. The cavity is present in similar proportion in both sexes, and it is more frequent when the eruption of these children is slowed.

Abstract

Key Words: Periodontal Diseases, Dental Cavities, Anamnesis, Epidemiologic Factors, International Classification of Diseases ICD-10

Objective: Characterize the oral health situation of patients that attend the clinics of a faculty of dentistry in the municipality of Cali. Materials and methods: A cross sectional descriptive study including 1341 clinical histories was carried out. The inclusion criteria were histories supported and approved by the professors in charged, excluding those for reevaluation and the unreadable. The dependent variables were the buccodental diagnoses and the independent ones were socio-demographics, consultation reason and oral hygiene habits. The diagnoses found in the clinical history were recoded according to the international Statistical Classification of Diseases (ICD 10). Results: The buccodental illness most prevalent was the dentine cavity (K021) 84% (lCg5%: 54-59) followed (lC95%:54-59) by acute gingivitis (k050) 57%. There was evidence of diseases that affect the patients' quality of life such as anodontia, malocclusion and dysfunctions of the temporomandibular articulation. Conclusions: The behavior of the buccodental pathologies in this investigation is very similar to the one reported at the national level. Keeping in mind that the dentistry faculties receive a high number of patients biannually the services offered should be geared towards by an epidemiologic profile that allows responding in a joint form to the problem of oral health. It is important to implement and/or to strengthen in the health faculties the international codification when issuing the buccodental diagnoses for the sake of having valid and reliable information and be able to carry out comparisons at regional, national and international level.

Both an interview that inquired about risk factors for periodontal disease and a clinical examination were performed to participants. The clinical variables, past history of caries, oral hygiene and current periodontal status were evaluated by three previously standardized examiners (Kappa: >0.8). Univariate and multivariate analyses were performed using linear and logistic regressions. Risk factors were introduced in a stepwise fashion when they were associated with the outcome at p <0.2. A significance level of 0.05 was established. Results: The prevalence of caries among cadets was 94% and that of periodontal disease was 91.2%. In average cadets have 2.5 decayed teeth. By the time they are promoted to a higher hierarchy degree, in average, they will have one more tooth affected by caries. Increasing the frequency of tooth brushing in once per day prevented 0.7 decayed teeth. A logistic regression model suggests that every additional year of age cadets experience an increase of 50% in the odds of having periodontal disease. The increment of one point in the OHIS (oral hygiene index simplified) increases three-fold the odds of having periodontal disease.Conclusions: Caries and periodontal disease are highly prevalent among cadets of the military aviation school. Our results support that the factors related to both outcomes are amenable to prevention.

It was carried out between the research groups of Institución Universitaria Colegios de Colombia (UNICOC) and Universidad de la Sabana, and financed by Colciencias. Objective: To determine the risk relation between the level of streptococcus mutans and Lactobacillus Acidophilus in saliva and ECC. Materials and methods: And analytical study of cases and controls was conducted on 119 children between 24 and 72 months of age, taking two cases for every control. A semi-structured survey was performed on the children to identify their socio-demographic characteristics and oral hygiene habits. The DMFT index and the ICDAS determined the caries experiences, and the O'Leary Index and the bacteria Caries Risk Test (Vivandet) determined bacterial plaque presence. The number of Streptococcus Mutans and Lactobacillus Acidophilus colony-forming units in saliva was measured; the data was processed with SPSS and the Epi Info program version 2000, using Chi-square for proportion, and OR for risk measurement. Results: The study found a statistically significant relation (p <0,02) between the presence of caries and the positive result of the Streptococcus Mutans (UFC> 105); 46 % of caries cases were positive for Streptococcus Mutans, and of the controls 18.6%. The OR was of 3,73 with a confidence interval of (1,42 - 10). Conclusions: The OR value indicates that the children exposed to a level of Streptococcus Mutans higher than 105 UFC have 3,73 times more probability of developing Early Childhood Caries.

Abstract

Key Words: Epidemiological Surveillance, Dental plaque, Dental caries, Oral Health

Objective: To develop a surveillance system wich allows to identify and analyze trends in oral health of population from 4 extramural sites from the community dentistry department between 2001 and 2007Methods: Individuals from the following extramural sites: Centro Santa María, La Salle, Fundación Ana Restrepo del Corral y Hospital San José were selected. A total of 293 clinical histories of adults and 635 of children were evaluated. An electronic questionnaire was developed in EPI-INFO for entering data extracted from clinical histories during the period 2001-07. Information regarding socio-demographic variables, oral hygiene habits and clinical indicators (dental caries, gingivitis, and dental plaque) were evaluated. Data was analyzed with the statistical package SAS 9.1. A descriptive analysis (table of frequencies and means) was conducted, and the prevalence of clinical indicators of dental caries was used to assess trends using Cochran's Q Homogeneity Test (p-value <0.05).Results: There are significant variations in dental caries among extramural sites during the period of study. No significant trends were observed in the presence of dental plaque among sites, although there are variations in the proportion of subjects who have gingivitis (from 43.6% to 89.7%). There have been significant changes in the decayed component (p<0.05), however there is not a consistent increase or decrease trend.Conclusion: Changes in the DMFT and the decayed component show increase and decrease peaks during 2001-07 related to the lack of continuing preventive programs.

Abstract

Key Words: maxillofacial trauma, causes, violence

Background. Maxillofacial injuries are a frequent condition in different countries; however, those are associated to diverse causes. Methodology: A descriptive study was performed from January 2001 to December 2006 at three hospitals and one institution from Pasto, Nariño, Colombia. Seven hundred one consecutive patients at “Los Angeles Hospital”, “San Pedro Hospital”, “Departamental Universitario Hospital” and Departamental de Medicina Legal y Ciencias Forenses de Nariño – Putumayo Institute were evaluated. Variables such as year, gender, age, anatomical distribution of fractures were included. Descriptive analyses were used to determine percentages and confidence interval values. Results: The most common causes were violence, which accounted for 350 (49.9%). Motorcycle accidents in 104 (14.8%), car crashes in 93 (13.3 %), and falls in 66 (9.4%). There was a substantial increase of violence in 2003 to 2004 years. 0 to 6 year-old child were involved to falls, while 15 to 24 year-old youth to violence, as well as motorcycle and car crashes. Violence was involved to nasal fractures, falls to nasal-orbital-ethmoid injuries, and motorcycle accidents and car crashes to politraumatism and panfacial fractures. Conclusions: Since violence, motorcycle, and car accidents were the major causes of maxillofacial injuries in youth, the public policies should be addressed to them.

Abstract

Key Words: Pulp capping, biomaterial, endodontics, cytotoxicity, flow Cytometry.

The most booming pulp covering biomaterial is Mineral Trioxide Aggregate MTA ProRoot ™, for its biocompatibility, radiopacity, good seal and induction of mineralized tissues. However, it is difficult to manipulate and high cost. El Bosque University has been conducting research to find an alternative therapy in endodontics. The purpose of the study was to evaluate the in vitro response of human dental pulp fibroblasts exposed to MTA ProRoot ™, Portland cement with bismuth oxide to 25% and Portland cement. The dental pulp fibroblasts exposed to the 3 cements reached confluence in a week maintaining a normal morphology. The flow cytometry profile to analyze cell viability showed a higher percentage for the MTA with a 83.82% (SD + / - 7.89) followed by the Portland Cement and Portland Cement more oxide Bismuth 25%. Concerning the analysis of cell proliferation in vitro largest cell proliferation was found with Portland cement with 96.33% (+ / - DS 45.64), followed by Portland cement more Bismuth oxide to 25% and the MTA but these differences were not statistically significant. In conclusion, biomaterials based in Portland showed a greater toxic effect in vitro compared with ProRoot MTATM, jeopardizing the viability of cells. Probably one of the components of Portland cement would be responsible for the initial cytotoxicity, future studies are needed to find the biomaterial of direct pulp capping substitute ProRoot MTA ™ in endodontics.

Abstract

Key Words: Portland, MTA®, Bismuth Oxide, Radiopacity

This study was conducted to determine the minimum concentration of Bi2O3 that would provide an adequate radiopacity to the Portland cement. For this study, a sample of five discs of compacted material was taken for each of the 7 evaluated groups: 1) MTA®, 2) Portland type I, 3) Portland tipo I with 20% Bi2O3 4) Portland type I with 25% Bi2O3 5) Pórtland type I with 30% Bi2O3, 6) Portland type I with 40% Bi2O3, 7) Gutapercha. To select the Portland type I mix with the smaller percentage of Bi2O3 the following parameters were defined: a low coefficient of variation, an average radiopacity between 6 and 7 mm of aluminum and a homogeneous radiopacity in the five samples. The radiopacity was evaluated on digital X-rays through the RadioVisioGraph (RVG) and measured with the aluminum grid on the same X-ray and analyzed with Image Tool™.The group selected for the best radiopacity was the Portland type I with 25% Bi2O3, which gave a radiopacity of 6.4 mm of aluminum ± 0.548 mm, similar to that of the MTA® (7 MM of AL). The different groups were compared and a statistically significant difference observed between all of them (p=0.000). It can be concluded that the preparation of the new Portland Type 1 cement with 25% Bi2O3 presents an adequate radiopacity of easier usage and cheaper than the MTA®.

Abstract

Key Words: Methionine encefaline, Endogenous opioid peptides, Pulp inflammation

Endogenous opioid peptides as Methionine-Encefaline (ME) act upon the nerve endings, stopping the freedom of neurotransmitters as SP, which intervene in the regulation of inflammatory processes. The purpose of the study was quantifying the cells that express Methionine-Encefaline (ME) in pulp tissue of healthy teeth and with clinical diagnostic of severe irreversible pulpitis by means of immunohistochemistry, taking into account the cellular type, with the aim of setting its possible participation in the regulation of inflammatory processes in the pulp. 13 samples of human premolar pulp tissue, extracted with exodoncy for orthodontic purposes, were observed in order to compare them with other 12 samples of pulps that had been clinically diagnosed with severe irreversible pulpitis. The tissue was set and processed in paraformaldehido to the 10% in order to perform the immunohistochemistry technique. The positive cells for ME by field were counted by means of electronic microscopic. The results showed the presence of endothelial cells, lymphocytes, fibroblasts, mastocytes, macrophages, odontoblastes and neutrophils, positive for ME, in both healthy pulps and inflamed ones too; no significant differences were found regarding the total account. However, there were significant differences related to the cellular type, in which the lymphocytes showed higher expression of endogenous opioid in healthy pulp tissue, compared to the inflamed tissue.

Abstract

Key Words: Ápex locator, Mini Apex, working length

The purpose of this study was to determine the level of accuracy of SybronEndo's mini apex locator during the CDC location whenit indicates a measurement of 0.0mm, confirmed with the Scanning Electron Microscope (SEM). 84 root canals were taken the mesial roots of permanent lower first molars extracted for periodontal or prosthetic reasons. These were separated from the distal roots, cutting them at the enamelcementum junction with a carbide disk at low speed. Later, the COE was made using #2 and #3 Gates Glidden burs, irrigating between each one of them with 5.25% of NaOCI. Then, SybronEndo's # 0.8, 10 or 15 K Flex files were introduced depending on the diameter of the canal. Asako's method was used to determine the work's length. The files were fixed inside the canal with fluid resin; subsequently, the file's handle was cut with pliers and the position the file's D0 observed with respect to the CDC, using the SEM at 400x magnification. The results show that on 85.7% of samples (72 root canals), the file's D0 are found between 0.0 and 0.5mm from the CDC, and on 14.3% of samples (12 root canals) it is found below the CDC. The ANOVA test did not find statistically significant differences, demonstrating the accuracy of the Mini Apex locator to determine the working length of the root canal during the endodontic treatment.

The aim of the present study was to evaluate the possible analgesic effects of 790 - 1064nm GaAlAs infrared laser after endodontic instrumentation of 170 necrotic teeth, medicated with 2% chlorhexidine solution. The teeth were divided into two groups, G1 (n=85) received laser irradiation (2J and 90J/cm2) after instrumentation over the apical region, on both buccal and lingual sides and in G2 (n=85) the laser was positioned over the same areas, but not activated (placebo group). The patients were instructed to fill a questionnaire about post operative pain 24 hours after the appointment, qualifying it in a four-grade scale: severe, moderate, light and no pain. Results showed that 35.4% in G1 had no post-operative pain and 26.4% in G2. There were no cases of severe pain in irradiated group and 3% in placebo group. Chi-square analysis revealed significant differences between these groups (p<0.05). The LLLT with 790 - 1064nm GaAlAs infrared laser was effective as a pain control alternative after endodontic procedures.

Abstract

Key Words: Root resorption, low-power laser, pain, orthodontic tooth movement, pulp changes

It has been shown that when performing orthodontic movements changes can occur in the pulp, root resorption and pain, for this reason it has been suggested the use of a low power laser for the modulation and the control of those changes. The purpose of this study was to evaluate the effects of the low power laser in pulp changes, the degree of pain and the quantity of dental movement in maxilary premolars subjected to intrusive forces of 4 ounces during twelve weeks. The total sample were 34 teeth, of whom 16 were taken to assess the pattern of normality, and the remaining 18 were divided into two groups, the experimental group, to which the low power laser was applied (GaAIAs of 810 nm), with a single dose of 18 joules after the activation of the orthodontic appliance, and the control group, to which the same procedure was performed but with a simulated laser application. The study evaluated the histologically changes in the dentino pulp complex and the presence of external inflamatory root rebsorption, the level of pain measured through a visual analogue scale and the quantity of dental movement in millimeters through a device developed for this purpose; finding that the low power laser has beneficial effects on changes in the dentino pulp complex, reducesthe severity of the external inflamatory root resorptions, the degree of pain perceived by patients and shortens the time of orthodontic treatment by accelarating the dental movement.

Abstract

Key Words: Friction, orthodontic brackets, orthodontic wires, glass thin film.

Objective: To compare the frictional, dynamic and static, resistance in vitro between ceramic brackets and stainless steel wires with and without glass coatings applied by the Sol-Gel method. Materials and Methods: 58 stainless steel orthodontic wires (0.016” x 0.016”) were prepared with and without glass coating applied by Sol-Gel. Subsequently, the resistance of the wires to in vitro dynamic and static friction over monocristaline-sapphire ceramic brackets was evaluated, and optical microscopy and SEM characterized the surfaces in contact.Results:Statistically significant differences were found between groups, the static (p=0.000), as well as the dynamic (p=0.001) friction group. The coated wires group presented both static and dynamic friction higher (static: 1.78±0.44N dinámica: 1.75±0.49N) than the uncoated wires group (estática: 1.37±0.31N, dinámica: .41±0.27N). The SEM characterization showed that superficial defects are produced on the coatings after the friction tests.Clinical Relevance: The evaluated coatings do not present results that permit its clinical usage in treatments that require sliding mechanics over monocristaline-sapphire ceramic brackets.

Objective: To determine harmony of cephalometric measurements between synthesized cone-beam computed tomography (CBCT) and cephalic lateral x-rays. Materials and methods: Descriptive cross sectional study with a population of ten Orthodontics and Maxillary Orthopaedics residents. The variables were the cephalometric measurements (S-Na, ENA-ENP, Na-Gn, Gn-Go, Ba-Na, Co-Go, Co-Gn, Na-ENA, ENA-Gn). The study included IV and VI semester residents, 20 to 40 years old, which needed orthodontic treatment and wanted to participate in the investigation. Pregnant women were excluded. The sample was selected for convenience. Ten (10) cone-beam computed tomographies and ten (10) lateral cephalic x-rays were taken. The gold standard was the CBCT from which the conformity harmony was analyzed with respect to the lateral cephalic x-ray, where the mentioned measurements were compared in the variables. The intraclass correlation coefficient was analyzed. Results: The findings from the pilot test showed a higher correlation between the CBCT and dry skull model (r =0.999) than the correlation between the lateral cephalic x-ray and dry skull model (r =0.980). The field test resulted in a correlation between (r=0.985) and (r= 0.781) for the CBCT and the lateral cephalic x-ray and an intraclass correlation coefficient (ICC) of 0.044. Conclusions: There is more harmony between the CBCT and the dry skull. On the other side, there are statistically meaningful differences between the CBCT and the lateral cephalic x-ray. There is correlation but no harmony.

Abstract

Key Words: Unilateral and Bilateral cleft palate, Elevator Muscle of the Palate Veil, electromyography, Videonasopharingoscopy

Objective: To evaluate the function of the elevator muscle of the palate veil in patients with cleft palate surgery reconstruction by means of electromyography. Materials and Methods: 19 patients from different institutions in Bogotá, were distributed in three groups. Group 1: 6 patients with right unilateral cleft palate surgery reconstruction, Group 2: 6 patients with left unilateral cleft palate surgery reconstruction, Group 3: 7 patients with bilateral cleft palate surgery reconstruction, were subjected to electromyography in a Cadwell Sierra Wave machine. After the application of topical anaesthetic, bipolar disposable hook electrodes (Nicolet) were inserted into the soft palate. The insertion was made under anatomical location of the right and left muscular bellies of the elevator of the palate veil and the activity recordings were made during insertion, swallowing and phonation. In addition Videonasopharingoscopy tests were performed on 12 patients, 4 of each group, to determine the presence of velopharyngeal insufficiency. A descriptive statistic was made, crossed Tables, Chi-square and nonparametric test of Wilcoxon, with a significance level of 0,05 (P<0.05). Results: The muscular activity of insertion was reduced in 47.4% of the patients in the right side and in 36.8% in the left side. During swallowing it was seen reduced in 63.2% of the patients in the right side and the left side; whereas during phonation there was a reduction in the activity in 68.4% of the right side and 78.9% of the left side. On the other hand, there was no association between the number of surgeries to which patients where submitted nor the absence of velopharyngeal insufficiency with the reduction of the muscular activity. Conclusions: Due to the reduced number of patients definitive conclusions cannot be established, nevertheless it can be thought that the activity of the elevator muscle of the palate veil in patients subjected to surgical reconstruction is affected.

Abstract

Key Words: Braces, Torque, pre-adjusted appliances, measurements

The purpose of this study was to determine the torque accuracy of new straight-arch stainless steel braces, with a 0.018-inch slot with Roth technique of three different companies. Using the probability method, a total of 286 braces were chosen as samples; 40 of them from 3M Unitek (Miniature Twin), 112 from GAC (Balance) and 134 from Morelli (Light with hooks in canines and premolars). These were divided by dental group according to the arch (superior and inferior) and by torque differences. The established tolerance range was based on Kiourtis data ±0,5º. The results showed that the 3M Unitek braces for the central and lateral inferior incisive, presented a torque 19% smaller than the nominal value. The GAC braces had a variation between a torque decrease of 2% in the central superior incisive and an increase of 38% for the first and second superior premolars. In the Morelli braces there was a torque decrease of 47% for the second inferior premolar and an increase of 146% for the superior canine. The 3M Unitek braces are the most reliable followed by GAC and finally by Morelli. The errors found, make it hard for the orthodontic treatment to be a precision process and demand a lot of attention from the orthodontist during placement on the teeth, in order to correct the torque error that the braces have.

Abstract

Key Words: Expansion, Early Treatment, Schwarz, Frankel 1

Purpose: A comparison of dental arch and cephalometric (measurement) changes after 1 year of treatment with two appliances for arch expansion during mixed dentition on class I-crowding patients. Methods: A randomized clinical trial was performed: two treated groups FR-1 (n=44), Schwarz plate (n=46), and one non-treated control group (n=41) with ages varying from 6 to 10 years old. Models were taken at T0 (pre-treatment) and T1 (1 year treatment); 12 cephalometric measurements were evaluated along with 3 inferior arch measurements: Little's Irregularity Index, intercanine distance and intermolar distance, analyzed with T-Student, Wilcoxon, and ANOVA.Results: Variables such as SNA, ANB, SN-PM, and ENA-Mn showed a significant increase associated with growth changes. At T1 there are no statistically significant differences between the non-treated group, FR-1 and Schwarz for Little's Irregularity Index (p=0.360). The type of treatment has and effect on I-PM with FR-1 (p=0.001) as well as with Schwarz (p=0.02) where an increase in measurement was observed with respect to the control group. The intercanine distance increase significantly from T0 to T1 (p=0.002) and it was not influenced by the type of treatment (p=0.272) or by time.Conclusions: After a 1-year observation there are no significant differences between the control group, FR-1 and Schwarz with respect to incisor irregularity. The cephalometric and model variables showed an increase associated with growth but not with therapy. The I-PM angle increased in the treated groups independently from the appliance used.

Abstract

Key Words: Bracket Positioner, Marginal Ridges, Leveling, Brackets, Typodont

The purpose of this investigation was to evaluate the efficiency of a bracket positioner created in the F.U.S.M whose referential points are the marginal edges of posterior teeth. This quasi experimental – type study constitutes the second phase of validation subsequent to the design and manufacturing of the prototype. The study was carried out on sixty pairs of posterior teeth held in ten (10) dental ridges (typodont). During the procedure, the braces were cemented with the positioner that would be evaluated, using a sequence of thermo cycled NiTi and stainless steel arches, until completing the leveling and aligning phase, measuring the posterior discrepancy on marginal ridges leveling in millimeters using a digital gauge, handled by a trained operator. This study found a statistically significance efficiency of 79% (p = 0) with the use of the positioner, perfect leveling of 27.6% as well as an acceptable leveling of about 42.5%. Further investigations are required in order to assess the effectiveness of this new bracket positioner compared to other devices or measuring charts.

Abstract

Key Words: Ferrule effect, prefabricated post, nucleus.

The purpose of this study was to evaluate in-vitro, the effect of ferrule preparation in the break off resistance of biradicular superior premolars, using prefabricated posts and also restored and slipped nucleus with complete crowns.A sample of 40 recently extracted human first maxillary premolars was used in this study. 20 teeth were decrowned 2mm coronals to the cement-enamel joint. After that, they were under endodontic treatment with LAP 40 and the palatine conducts were deshuttered to get prefabricated posts and slipped nuclei; they were divided in the following way:Control group A: 10 teeth under endodontic treatment and rehabilitated with ferrule effect; Experimental group A: 10 teeth under endodontic treatment and rehabilitated with slipped nuclei with ferrule effect; Control group B: 10 teeth under endodontic treatment and rehabilitated with prefabricated posts without ferrule effect; Experimental group B: 10 teeth under endodontic treatment and rehabilitated with prefabricated posts with ferrule effect. The teeth were rehabilitated with complete metallic crowns and taken to a universal proof machine. A compressive charge was applied with a 15 o angle at the palatine surface until the tooth was broken. The t-student and chi-square test was used in order to prove the presence of significant differences among measurement groups. The results were evaluated based on a significant level of 1% to 5%. The results show that there is no significant difference at 1% to 5% in the resistance to break-off of the superior birradicular premolars under endodontic treatment and rehabilitated with slipped nuclei or prefabricated posts using ferrule effect in both systems, as the T-student result was 0.541, which is between ± 2,878 and ± 2,101, with levels of 1% and 5%, respectively.

Abstract

Key Words: Class I, Class II and Class III Malocclusions; vertical and horizontal growth pattern.

Objective: To compare the changes produced in the facial, dental and skeletal features of patients with bad occlusion type I, II and III, based on their growth pattern.Methods: A non-experimental descriptive study was performed in a sample of 100 orthodontics patients from the postgraduate program at Pontificia Javeriana University, 10 to 20 year-patients with bad occlusion type I, II and III were chosen; they will have complete clinical, photographic and radiographic registers, pre and post treatment. Cephalometric measures and traces were performed in order to determine the facial, dental and skeletal features of the bad occlusion, pre and post orthodontics treatment, based on the growth type. The data were registered in the measurement instrument and descriptive statistics with parametric methods such as chi-square to determine the significance of the changes. Results: Differences were found in the bad occlusion features when classified according to the growth pattern. Significant statistical changes were found in facial and dental characteristics during the orthodontics treatment, differing from the skeletal characteristics, which did not change significantly.Conclusions: It can be concluded from the current investigation that the growth pattern affects the expression and severity of bad occlusion characteristics, but it does not affect significantly the response to the orthodontics treatment. It can also be concluded that the orthodontics treatment can change certain facial and dental characteristics, but it does not interfere with skeletal ones.

Abstract

Key Words: Brackets no microarenados, Brackets microarenados, fuerzas adhesivas de cizalla.

Introduction and Objective: The manufacturers of orthodontic materials have tried to modify the features of the brackets base, in order to improve the forces of the interface resin/bracket union. The purpose of this study was to compare the adhesive forces of the metallic brackets cizalla without any addition Mini 2000 and with addition of titanium oxide particles, Mini Twin from the commercial house ORMCO®.Materials and methods: 60 premolars extracted for orthodontic reasons were conserved in saline solution to 0.9% at 4oC during 5 months; before the brackets' cementation, the premolars were assigned randomly, 30 in the control group, no added, and 30 in the experimental group, added.Once the thermocycle with 80 cycles, during 2 minutes each, was performed at 5oC and 55oC, the teeth were tied to an own designed machine and taken to the trial machine, Instrom 5582, to submit them to the Cizalla's force. Microphotographs were taken with the electronic microscope, before and after the cementation failure. Results: No significant statistical differences were found regarding recollection time of the premolars, Value p: 0.876 for the MannWhitney test, indicating that the groups are comparable from the beginning. Significant statistical differences were found regarding resistance to cizalla's forces, Value p: 0.005 for the MannWhitney test, in which the non-added brackets resist a higher force before the bracket off cementation, with a Me: 188.4 N +- 79.0. Conclusion: The microarenado process of the brackets' base with the aim of increasing the adhesion forces is an unnecessary procedure as it spends time and money from the manufacturing houses.

Abstract

Key Words: Oral habits, atypical deglution, interdisciplinary management.

In the local environment, there are few studies that register the interdisciplinary atypical oral deglution habit. This necessity made the investigators perform this study with the aim of characterizing the issues related to the interdisciplinary manipulation of atypical oral deglution habit through the analysis of experts' information and the existence bibliography.This investigation is qualitative. It's framed under a historic-hermeneutic paradigm, developed through an exploratory study, using interpretative techniques for the textual analysis. The population was made up of: a) Professional opinions (General dentists, odontopediatric, orthodontist, otorrinolaringologist, fonoaudiologists and psychologists), who treat patients with deglucion atipica; b) Texts and magazines that deal with this topic. The techniques included documental inspection and investigation, which was developed through a structured interview, applied to professionals from different health branches.The main findings show that the situation which influences positively the treatment of the atypical oral deglution habit, is the availability of a good interdisciplinary team that avoid repetitions in the treatment and improve the fast evolution of the patient. Besides, the elements to keep in mind when performing remissions are: anatomic alterations in the patient, his/her economic situation, his/her access to another professional, patient's possibility to have an alternant appointment (interappointment) and his/her access to health service.

Abstract

Key Words: mini-implant, impacted canine, anchorage.

Objective: to describe the behaviour of a mini-implant used as orthodontic anchorage for traction in a patient with a palatally impacted maxillary canine. Materials: A case report was conducted for a female patient, 34 years old from the UCC Orthodontic clinic, Bogotá Sectional; the patient presented a diagnostic of palatally impacted canine and satisfactory systematic conditions to implant a mini screw. A set of 22 slot Roth metal brackets is cemented from 6 to 6 upper and lower with reinforcement of anchorage. During the period of work the spaces for the canine and the insertion of the mini-implant are created. After 10 months of treatment a surgery is done to insert the mini implant. Seven days after the surgery the implant is loaded with elastics 3/16 and the initial tomography (T1) is taken. Follow up controls are taken to evaluate the state of the mini-implant, the peri implant area, and the state of the ligature of traction. At 3 months of treatment a final tomography (TF) is taken to compare the changes during this time, and as an additional result to evaluate the amount of movement of the canine. Results: a comparative assessment between the initial and final TAC with a superimposition of cephalometric tracings (black: initial; red: final) is done to evaluate the amount of vertical and horizontal mobility of the mini-implant; it was found a total coincidence in both tracings, two planes were traced to have angular measurements that would allow to find differences; It was found 1° of difference between TAC1 and TACF. Respecting the grade of inflammation in the peri-implant area no change was found in the soft tissue. To evaluate the amount of movement in the canine, 3 tomography sections are taken as guides and horizontal and vertical lineal measurements are traced, and it was not found any movement of the canine. Conclusion: during the period of traction there was neither mobility of the mini-implant nor inflammation in the surrounding areas, although is shown 1° degree of difference of axial inclination of the mini-screw towards the force direction. The palatally impacted canine has not moved with the strain put on it to traction it.

Abstract

Key Words: Cleft lip and palate, orthopedic plate, maxilar orthopedic

The cleft lip and palate is a congenital malformation, constituted by structural deficiencies characterized by the absence of the union between some processes of the face in formation. Actually there is an orthopedic treatment that can be initiated since the patient born. It consists in the use of an acrylic plate, which main role is guide the growth and development of the process that are separated by the cleft. Objective: The purpose of this study was to evaluate the evolution of the cleft lip and palate in the transverse dimension in the patients been born in the Hospital Universitario del Valle and look how this cleft change before the surgery of the cheiloplastia with the use of the orthopedic plate during three months. Methodology: the sample consist in 6 patients with cleft lip and palate who began the treatment early with the use of the orthopedic plate before they had 30 days of been born, the patients were indicated to use de plate during 3 – 4 months before the first surgery of cheiloplastia. During this time they received controls every 15 days and impressions every month because in the study were registered 3 meditions from the anterior, the middle and the posterior part of the clefts of the casts from the patients. Results: The more significant change was found in the anterior part of he cleft. The posterior part from the cleft was the more stable part with a little change. For the results in this study we recommended an early orthopedic treatment for the patients with cleft lip and palate to have a significant change in the cleft and decrease the risks post surgery.

Abstract

Key Words: Streptococcus mutans, Dental caries, Predentate infants

Objective: To establish the time of appearance of Streptococcus mutans (SM) in the oral cavity of healthy predentate infants. Material and Methods: A descriptive observational cross sectional study was done. Samples of tongue dorsum, using sterilized swabs, were collected from 75 predentate, 1 to 7-month old infants that attended two low income health institutions in the city of Bucaramanga. After inoculation and incubation typical morphotype colonies were isolated and identified by biochemical tests (sugar fermentation and catalase test). The presence or absence of SM was analyzed with the following variables: bottle feeding, maternal caries (dmft index), habits (kisses in the mouth of the baby) and the mode of delivery. Means, modes, medians and standard deviation were determined for all data. Bivariate analyses were performed by chi square test, Student's t test and Wilcoxon test. For all tests, p<0.05 was considered statistically significant.Results: SM was detected in 15 (20%) of 75 predentate infants with a mean age of 4.1 + 1.7 months. Out of the 15 mentioned before, 8 (53.3%) were bottle fed and the mothers of 13 (86.7%) presented dental caries. The only statistical and biologically significant variable found was kisses in the mouth, since 9 (60%) of the children in whom SM was detected were kissed in the mouth. Among infants who presented SM, 9 (60%) were vaginally delivered and 6 (40%) were delivered by caesarean section. Conclusion: Streptococcus mutans was found in the mouth prior to tooth eruption in 20% of the infants studied. The children who received kisses directly in their mouth registered a statistically greater association of presence of SM in oral cavity compared with the children that did not (p=0.01).

Abstract

Key Words: Airway, orthognathic surgery, oral physiology

The orthognatic surgery is an alternative treatment for patients with skeletal maxillomandibular discrepancies. In this procedure, the osseous and soft tissues from the facial cranium are modified, including the aerial way. The purpose of this investigation was to make a descriptive analysis of the cephalometric changes in the aerial way in twenty patients, eleven women and nine men, who have gone through bimaxilar orthognathic surgery at the San Vicente de Paul hospital, (HUSVP) in Medellin, Colombia.A set of three lateral cephalometric radiographs were taken. The changes in the aerial way were compared to those ones before the surgery, and after the eight and eighteen months after the surgery. The radiographs were scanned and digitalized, evaluating area and lineal measurements from the aerial way. Significant increases in the upper pharyngeal space and oropharyngeal area were found in patients after the surgery. The lower pharyngeal space and the hypopharyngeal area showed no significant increases. Significant differences in hyoid bone position were found between men and women.We can conclude that the bimaxillary orthognatic surgery increased the upper aerial way dimension. These changes were determined by the surgical procedure and the dimension of the maxilla and mandible's movements. Besides, changes in the soft palate, hyoid bone and tongue's positions were observed.

For inferior maxillary: (E) from the jaw's inferior border and passing by the symphisis; (F right - left) passing by the mental foramen; (G right - left) passing 5 mm. behind the mental foramen; (H right - left) passing 10 mm. behind the mental foramen. All the measurements were made in the pre-surgical, the immediate post-surgical, and at the nine months.Results: The different points from the superior maxillary (PPMXS) were averaged out and a loss of height was observed (between 6.29% and 33.6% with an average of 17.36%). On the inferior maxillary (PPMXI) a variation was observed from a gain of 6.31% to a loss of 18.87%, with an average of 2.54%.Conclusions: The HA implant allows the restoration of an adequate height of the alveolar rim. The height of the alveolar rim initially obtained displays a 17.36% loss of height in the superior maxillary and a 2.54% loss in the inferior one during the nine months observation.

Abstract

Key Words: Oral mucositis, leukemia, chemotherapy, oral rinses

The present study was conducted to compare the effects of three different oral rinses in the treatment of oral mucositis induced by chemotherapy in children between 3 and 15 years old, with acute lymphoblastic leukemia who were hospitalized at the Pediatric Hematooncology Pavilion of the San Vicente de Paul Universitary Hospital in the city of Medellin.The type of study was a quasi-experimental comparative blind design, and collection of the sample was made over a period of 32 months between April 2005 and November 2007.Three rinses were compared: Triconjugate composed of diphenhydramine, milk of magnesia (magnesium hydroxide), lidocaine and nystatin; Sucralfate comprising sucralfate suspended, lidocaine and nystatin; and a third rinse, called Control consisting of lidocaine and nystatin, medicines that were also part of the triconjugate and the sucralfate.The sample had 14 cases. Rinses were assigned randomly and groups were distributed as follows: triconjugate with 6 cases, 4 in the sucralfate group and 4 in the control group (there were two cases that were lost for reasons unrelated to researchers). Each group had 3 daily rinses with the assigned mouth rinse and a daily log was made with information related to the severity of mucositis and duration of the episode. Additionally some demographic variables were registered. No statistically significant differences were found between the rinses used, and some similarities were found between the behavior of rinses depending on the length in days and the degree of mucositis found.

Abstract

Key Words: Maxillary cysts, vitality, sensitivity, and bone repair.

Cysts represent a pathological cavity covered with epithelia, that normally contains a liquid or semi liquid material and involve dental organs that in certain cases are not the ones that produce the pathology directly; some authors recommend endodontic treatment prior to surgery in order to prevent lesions to the nervous-vascular package. It is essential to choose a treatment that guarantees complete elimination of cysts, at the same time as it preserves the vitality of the dental organs included radiographically in lesions.This is a descriptive study of cases that evaluate the vitality of teeth affected by maxillary cysts before and after enucleation; for this it was possible to obtain a sample of 10 patients during the study period, preserving the pulp vitality of 32 dental organs. Sensibility tests were carried with ENDO ICE to evaluate pulp vitality and the lesion size was measured radiographically, to appraise the bone reparation, in both cases before and after the enucleation, during a post surgical period of 6 months. 100% of all the evaluated dental organs preserved their vitality; 100% of the bone defects decrease by 23% after 6 months of post surgical treatment.

Abstract

Key Words: Dental Implants, Bone Integration, Implanthology, Bicon.

Implanthology is a reliable common resource for solution of a great amount of clinical problems. This treatment represents an alternative to handle the replacement of lost teeth through a bone integration process.At the Dentistry Faculty of the University de Cartagena, bone-integrated BICON® implants were completed from 1997 until the beginning of this investigation; the development reports of these implants were unknown. The purpose of the following study was to evaluate the current clinical and radiographic state of the bone-integrated implants, between 1997 and 2005. The study used an observational design (descriptive evaluative transversal), including 24 patients which met the selection criteria, and assessed 67 implants taking into account the following guidelines: color and size of gums, implant mobility, oral hygiene, and bone absorption by means of periapical x-rays corresponding with each implant. At the end of the evaluation each patient received a test through which we determined the level of satisfaction with respect to his/her dental implant. Out of all the evaluated implants, only 4.2% presented the highest index in all the studied variables. Out of these, 1.3% was removed from the oral cavity. We can assert that dental implants are an excellent alternative among the various rehabilitation options offered in Dentistry.

Abstract

Key Words: Moorrees Method, dental age, stage of dental development, radiographic dental development,legal-odontology report.

Background: In judicial and administrative processes, one of the reports authorities most required is the clinical age, being the dental age one of the parameters for its estimation. The dental age is based on the information about the crown, root and emergency process of the tooth. There are many methods to estimate the biological age, although their application can vary because of the wide ethnic differences in population, which can influence the dental formation, development and eruption. Objective: Characterize the 12 to 21-year population from Bogota, to set a dental development pattern, which can be applied to the dental age legal report. Methods: A transversal cutting design study was carried out; it was analyzed based on Moorrees' scale, 441 panoramic radiographs of 12 to 21 year people from Bogota with complete dental clinical history, taking into account etary group, gender and socio-economic level. Results: Men and women follow growing patterns through similar increasing functions, suggesting no significant differences between contralateral and ipsilateral teeth, neither the profile of the growing patterns according to the socio-economic status. Conclusions: People ages between 12 and 13 years have significant differences in the dental development of canines and premolars, being significantly higher the stadium of development in women; from that age on, the development level in men and women evens up for being significantly again at the age of 20 and 21, but only in third molars.

Abstract

Key Words: Substance P, Zone inmunohistochemical, Neuripeptide, Corpses

The purpose of this study was identifying the presence of substance P in the retrodiscal zone of the TMJ in dead human bodies and its relationship with the inflammatory and traumatic processes (Temporomandibular disorders) –TMD- . 10 dead bodies were studied, 6 men, 4 women, 20 joints; extracting part of the articular disk and the right and left retrodiscal area. Each sample was subjected to the inmunohistochemical process and marked with a monoclonal antibody P to determine the presence of the substance and its concentration degree. The P substance was found in 95% of the joints, in 1 5%, it was not found. The U de MANN-WHITNEY non-parametric test was used, obtaining a sample distribution by genders, 40% for women and 60% for men, with a signification level p>0.05. The results were not statistically significant due to the sample size. Substance P is one of the most evident neuropeptids in the retrodiscal area when there has been an inflammatory process in the temporo-mandibular joint (TMJ).The results suggest that the neuropeptids are related to the TMD. The fact of finding high levels of inflammatory measurements can be a valuable diagnostic method to discover the biochemical events in the TMD, the results of this study should encourage the investigation of potential uses in order to be set as reliable diagnostic.

Background: The secondary dentine apposition has been proposed as a biological index in different age estimation methods for human identification. Objective: To determine the relationship between the secondary dentine apposition and the chronological age in a sample of adults from Bogota D.C., with the purpose of adjusting a mathematical model to estimate the age in adults for forensic identification purposes. Methods: The study was correlational descriptive. The study sample was made up of 107 subjects (49 men, 58 women), ages 21 to 50, who got a digital periapical radiograph from the superior central incisive taken, in order to perform a metrical analysis from the chamber and radicular conduct, using the Scion Image Version Beta 4.0.2 program. Results: The highest Pearson correlation coefficient had a proportion of b/B (-0.59), followed by simple measurements b and c, that had coefficient of -0.56 and -0.43 respectively. The mathematical models showed a margin of error of 7.1 years. Conclusions: There is an inverse relation between the secondary dentine and the age. The measurements performed at radicular level and the widths showed higher relation with age. The first mathematical model was: Age = 56.07 – 140.61b/B con R2 = 0,36. The second model with simple measurements was: Age = 38,72 – 26,35b + 5.52B – 0.72 LTP with R2 = 0,38. This age estimation method does not require histological cuts in adults, which lets its application in live people and archeological samples.

Abstract

Key Words: Holistic Schooling, Pedagogical Practice, Roles, Interactions.

Introduction: The on hand research offers an account of the shared sentiment held by the postgraduate educational community concerning holistic schooling. The assembled reference framework is a result of the notions, the pedagogical observations, roles and interactions that the academic community acknowledges and establishes for holistic schooling. Methods: Qualitative research of interpretative character was conducted. Said study went through the point of view, meaning, intentions and expectations the educational community (experts, masters and students) has regarding holistic schooling. Results: From the acquired educational community accounts one is able to declare that three existing disciplinary aspects to explain holistic education exist: the philosophical, the sociological and the psychological, permitting an existentialist, material and interactional vision, as a new arising horizon for the same. Conclusions: This holistic schooling reading, interdisciplinarily seen, would seek out: from philosophy, a phenomenological and existentialist sense, a dynamic whole, critical, dialectic and permanent for the individual´s social structuring. Sociologically, under a material and dialectic stance would foster structuring for human kind´s makeover and that of its world. Psychologically, from an interactional horizon, would seek out, under conversational acts, the individual´s schooling for undertaking decision making as a positive something.

Abstract

Key Words: Adults education, empirics, dentistry, learning, cognitive styles.

The investigation “Learning processes in empirical adults (dentists) education, for the development of productive and academic competences” is being developed during 2 years, at the Autonoma de Manizales University, with 53 adults from the Dentistry program. They are subject of investigation. The regular students from the Dentistry program serve as parameter of comparison. In this investigation process, the characteristics, central and emergent categories of human and learning development were reached. The subjects' cognitive dynamic and structure was recognized, the university academic dynamic of appropriation was also recognized, based on new cognitive styles that the subjects have to assimilate. The investigation approach is based on a descriptive and interpretative style, as a permanent construction of theory, diagnostic intervention, observation processes, interpretation of the information and sense construction. The information collected through interviews and surveys is submitted to structural synthesis, as a journey and sense. From here, new categories emerged, which were defined from a humanistic development, such as: socialization, morality, affectivity and emotivity, thought, motivation, corporality and movement, learning, adulthood, productivity and filiation. The investigation does not end here, due to its own characteristics, considering that is a high significant process for the institution, investigation subjects and dentistry in general.

Abstract

Key Words: Educational community, Curricular design, Participation, Curriculum, Social actors.

This assignment presents the substantial aspects by characterizing the design or curriculum practices, obtained through the result of two investigation projects, one of them about the eight academic bachelor programs from the Health Faculty at the Valle University, including the dentistry program. The study used three information ways: documental analysis, interviews through focal groups and surveys or questionnaires applied to a representative sample of students, teachers and directives. The educational institutions must open reflective spaces as an element of interaction during the construction of the curricular proposal, counting not only with teachers, but also with the direction, students, administrative personnel, graduates and members of the society, with the aim of redefining their pedagogical and curricular practices, because it turns out complicated to unify curricula that do not meet the real social contexts. The construction or adjustment of any curriculum that deals with social issues must have descriptive studies of the community, in order to detect experiences, interests, daily perspectives and real useful necessities to guide the curricular activity. Participation spaces must be opened directly with members of the educational community or through its representatives.It is necessary to recognize and introduce new learning proposals with a serious investigative support, committed with the country's education and the social necessities of our contexts.

Abstract

Key Words: raffia, dental floss, interproximal oral hygiene, bacterial plaque.

Objective: To determine the effectiveness and patient acceptance of the alternative raffia-type material for cleaning interproximal surfaces.Materials and Method: Ninety-six young individuals participated in the control group of an experimental double-blind study, while one-hundred five young individuals were selected for the experimental group. The study had an eight-week duration. Subjects had three training sessions dealing with the use of materials related to cleaning interproximal surfaces. The study obtained the pre and post bacterial plaque indexes by using the modified Quigley-Hein plaque index, gingival index of Loe and Silness, and presence of grooves in the interproximal papilla as well as lip comissures, through the record of a map of soft tissues. Moreover, the subjective evaluation suggested by Hannes et al. was administered.Results: A significant difference was observed between the average of the initial and final plaque indexes and the average of the gingival index in individuals who used the raffia (p 0<0.05) and individuals who used the material of the control group (p < 0.05). A greater proportion of subjects found raffia prone to tear, harmful for the fingers and thick, and difficult to introduce it between teeth, and uncomfortable to use.Conclusion: Raffia was effective in the removal of the average of bacterial plaque index and gingival index. The user's acceptance of the alternative material presented problems related to the comfort in the use of raffia.

Abstract

Key Words: Preeclampsia, periodontal intervention, outcome, pregnancy, control clinical trial.

Introduction: There is an association between periodontal illness and increasing of pregnancy complications. It was recently demonstrated that the periodontal treatment (PT) decreases the premature labor and low birth weight. The PT effects in preeclampsia are unknown.Objective: To determine the effects of PT on the pregnancy outcome in patients with slight preeclampsia.Methods: In a control clinical practice, women with slight preeclampsia were classified in two groups: Group PT and Control Group. A calculation was made about the patients who advanced to severe preeclampsia and eclampsy were calculated, number of days of clinical stability after the inclusion and percentile of the new-born weight adjusted to the gestational age.Results: 61.7% had periodontal illness. There were no differences in the socio-demographic, obstetric and periodontal features between groups. There were no medical complications attributed to the periodontal treatment. The progression to severe preeclampsia or eclampsy was similar in both groups (89.2% versus 84.4%, p= 0.65) (OR= 1.06 IC 95% 0.87-1.129, P = 0.7), the same for the stability days (Median: 10 days, range 1-46, 12 days, range 1-59), the new-born weight percentile was similar in both groups ( Percentile median 50 range 5-90 and percentile 55 range 5-95) between the TP and Control groups, respectively.Conclusions: The active periodontal illness is frequent in women who suffer from preeclampsia. The periodontal PT doesn't increase the risk for the new-born and mother's health in women who suffer from preeclampsia. There were no significant changes in the pregnancy outcome.

Abstract

Key Words: Translucency, dental cap, spectrophotometer, alumina, zirconium

Objective: To compare the maximum translucency grade of dental cap materials for totally ceramic restorations: sintered aluminium oxide glass-infiltrated aluminium oxide sintered zirconium and glass-infiltrated zirconium. Methods and materials: In-vitro tests: twenty 10 mm x15 mm lamellas 0.5 mm thick were used: five pieces were made of glass-infiltrated aluminium oxide (Vita A2), five of sintered aluminium oxide (Vita A2), five of glass-infiltrated zirconium (Vita Colour A2), and five of sintered zirconium. To measure and compare the translucency of each material a spectrophotometer was used, which determined the translucency of light with respect to the wavelength, within the visible light spectrum. Translucency was the studied variable. Results: According to ANOVA, a significant translucency difference was found among sintered aluminium oxide (In Ceram Vita Zhanfabrik Colour A2), glass-infiltrated aluminium oxide (Vita Blocks Colour A2), sintered zirconium (In Ceram Zirconia Vita Colour A2) and glass-infiltrated zirconium (Vita Blocks Colour A2) P= 0.001. According to Microsoft MicroCal Origin 6.0, the bigger the area below the curve, the higher the translucency. Based on a positive control sample of feldspathic ceramic, sintered aluminium oxide showed a 16.544nm^2 area and 63% translucency, being this the most translucent material, followed by glass-infiltrated aluminium oxide, with an area of 9.021nm^2 and 34% translucency; sintered zirconium had an area of 8.996nm^2 and 34,3%, and in the last place glass-infiltrated zirconium showed the lowest translucency with an area1.554nm^2 and 5,9% translucency. Conclusion: Sintered aluminium oxide is the filling material with the highest translucency value while glass-infiltrated zirconium is the material with the lowest value.

Abstract

Key Words: Titanium implants, immediate loading, primary stability, insertion torque.

Introduction: Immediate loading of implants has become a viable treatment alternative that offers multiple benefits for patients such as providing immediate function and esthetics, reduction of surgical trauma and of the total treatment time. A controlled prospective trial was conducted for the placement of implants in clinical cases of single tooth restoration, which gathered the proposed consensus in recent literature to evaluate the clinical success under the protocol of immediate loading. Materials and Methods: Twenty-one Renova® (Lifecore Biomedical Inc., Chaska Mn.) implants with internal connection and textured surface (RBM) were placed in 17 adult patients (6 male, 11 female) with ages between 18 and 74 years old, systematically healthy, and in need of single tooth replacement in the anterior and premolar sectors of both maxillaries. Results: The cumulative success rate after 18 months for this study was 95.2%. Success values comparable between both the protocol of immediate and conventional loading were obtained, and a direct correlation was found between the distance from the bone to the point of contact and the percentage of papilla in the interproximal area.Conclusions: The results from the present study indicate that treatment for a missing tooth in the anterior and premolar areas with titanium implants (surface-treated and threaded), with a primary stability measured in torque of at least 32N/cm and without occlusal function is a viable treatment alternative with success rates comparable to those of conventional loading.

Abstract

Key Words: Implant, Abutment, Connecting Screw, torque, Preload, Elongation, SEM, Elastic limit,Poisson Coefficient, Proportional Limit.

The purpose of the research was to determine changes in elongation of the abutment-connecting (titanium alloy) screw due to momental forces higher than those recommended by manufacturers (Lifecore, Biolok and Imtec) and to evaluate SEM microscopic changes on the surface of the screw threads and implants. After torque was applied, titanium-alloy pillars where plotted for the 3 systems; torque was applied using a universal Tohnichi torque meter. A sample of three specimens was taken for each manufacturer; None of the tests exceeded 50N/cm due to the poor resistance of the union of the screw head with the torque keys for each of the manufacturers, with the exception of Biolock, which reached a torque of 70N/cm. The other groups presented various damages with the ratchet-key connection and the screw head. Through microscopy, it was demonstrated that in all of the groups there was contact between the superior plane of the V-shaped threads and the inferior plane of the implants. The greatest elongation was observed on the Imtec group (0.05mm) and the lower one reported on the Lifecore group (0.01mm). It was concluded that it is possible to over tighten the connecting screws by 30 to 150% with respect to the torques recommended by the manufacturers, without fracturing the screw.

Abstract

Key Words: Initial Interproximal lesion,.Primary molars, Interproximal sealing

Introduction: At the age of 3 cavitated caries show up on children's molars, mainly on the distal surface of the first one; dentinal lesions on primary teeth progress twice as fast as on permanent teeth. Sealing of interproximal lesions has shown to be effective on adults. On preschoolers the technique has shown a “definitely-positive” behavior (Frank-Behavior-Rating-scale) and very-low pain intensity (Visual-Analogue-Scale-of-Faces, Reis-Barreto). Objective: To assess for 12 months the efficacy of sealing approximal initial lesions vs. flossing instructions on distal surface of primary molars.Materials and methods: Fifty 4-6 year olds from Colombia (n=27) and Denmark (n=23) participated in this split-mouth design. Patients had to have a minimum of two approximal lesions scored 1-3 according to the following radiographic classification: (1) lesion restricted to enamel-outer-half; (2) lesion from inner-half of enamel to the enamel-dentine-junction; (3) lesion restricted to outer-third-of-dentine. Standardized baseline and follow-up bitewing x-rays were obtained. The lesions were sealed with an adhesive. Patients' parents/guardians received a brochure with flossing instructions. The progression of lesions was assessed by means of pair-wise reading of conventional bitewing x-ray. McNemar's test was used to assess differences between test and control (significance level p <0.05).Results: At the end of the study, 6 test and 9 control lesions were restored. Test vs. control progression: nTest = 15 (30%); nControl = 30 (60%); p<0.01. Conclusion: The sealing technique was superior to flossing instructions after a one-year follow-up.

Key Words: Caries, chemistry removal, TRA

Objective: To compare the Atraumatic Restorative Treatment (ART) with the Atraumatic Restorative Technique Modified (ART), using papaya base gel “papacaries” in the cavitational cavities removal. Materials and methods: Through a clinical, masked, random, non-control essay, cross-over design, the TRA-conventional and TRA-modified techniques were compared using papacaries, the operator confidence level was observed during the removal of caries tissue, the working time and the anxiety of the treated patient. Results: 14 children, ages 5+/-2.0 were evaluated. The 71.4% (10) of the target population are men. The 50% (7) of the total population are in the socio-economic level 1. A higher removal facility was identified (71.43%) by applying the modified Atraumatic Restorative Technique, using a papaya gel with a security level of 100% in the removal of caries tissue. The children presented a higher anxiety level treated with TRA-conventional. The working time was higher in the modified technique with a difference of 1.52 minutes. The radiographic and clinical evaluation performed three months later, permitted the evidence of caries, fistule and edema lack, in the treated teeth through two types of procedures. A change of color was observed in one tooth, which received treatment of caries removal by TRA conventional and a restorative disadaptation was evident by observing with a magnifying glass the treated teeth with the two techniques, being superior in TRA modified with a difference of 14,28%.conclusion: The TRA-modified reduced the anxiety level in the dentistry appoint, being a great advantage if we keep into account the difficulty of approaching a pediatric patient in a dentistry treatment. The operator shows more security because of the facility of caries removal, his working time when using papaya gel is longer than working without any chemical; the time difference is compensated by the operator's security and the patient's calmness. When performing the short-time evaluation (three months), there was no evidence of fistule and edema for the clinical examination with the two applied techniques. The TRA modified presented higher disadaptation levels than the conventional TRA, at the same time the color change of the dentine surface was evident with the TRA application.

According to the ENSAB III, COP values range from 0.1 to 2.3 and ceo value is 3.0; both villages are within the rank. Conclusions: People from Chuscalito have better life standards than those from San Juan. Consequently, both villages show different conceptions, problems, and access to health services; as an example, people from Chuscalito visit their dentists when feeling a pain, while people from San Juan take acetaminophen for the same purpose. These results allow preparing action plans as well as execution proposals with the purpose of achieving better health indicators.

Abstract

Key Words: Anxiety, dental anxiety, test anxiety scale, dental care.

This investigation was carried out in alliance with investigation groups from Schools of Colombia and the University Foundation Konrad LorenzAim: To establish the level of convergent validity at the multi-method level, between the dentist's observation on anxiety and the patients self report. Method: Multi-method descriptive comparative study, having as population 132 dentists and 913 of their patients. To measure the patient's anxiety the scales MDAS and SDAI were used, and a semi-structured instrument was created for the dentist's report. The statistical analysis used descriptive statistics of frequencies and percentages, analysis of variance (ANOVA) and the Kendall's T Results: Among the main behavioral manifestations identified by the dentists the patient's report was found in 65.2% of the cases, followed by an increase in the perspiration level with 55.37%. The main strategies reported by the dentist to control anxiety were: giving the patient confidence 30.3%, and explaining the treatment 22%. There was a statistically significant convergence level of p=0,000 between the dentist's report and the patient's self report Conclusions: The dentist identifies in a suitable way the different indicators of anxiety, using behavioral strategies in his/her relationship with the patient, without making a lot of use of therapeutic strategies.

Abstract

Key Words: Silicone impressions, blood, biosecurity, disinfection, Luminol.

Objective: To determine the presence of blood in the silicone impressions for fixed prosthesis that arrive at the dental laboratory and to identify the knowledge level of students about the disinfecting protocol of silicone impressions. Materials and Methods: Cross sectional descriptive study; sample by convenience of 49 silicone impressions sent by dental students to the dental laboratory; The forensic medicine technique, Luminol, was used by and expert for blood detection; then a questionnaire was given to students to measure their knowledge about the protocol for handling silicone impressions. Results: 93.8% of impressions were positive to Luminol. 100% of impressions that came from

th thstudents of 7 and 9 semesters were positive. From the 30 questionnaires analyzed, 80% of students reported not disinfecting the silicone impressions before sending them to the lab. From the 20% of the students that disinfect the impressions 50% use quaternary ammonium salt. 96.7% (29/30) of students surveyed thought that disinfection might alter the impression's stability. Conclusions: Almost all the students (96.7%) think the disinfection and sterilization process might affect the dimensional stability of the silicon impression. In addition, none of the students were familiarized with the correct protocol that they were supposed to follow; These situations strongly influence the high prevalence of positive results of the Luminol test on the silicone impressions.

Abstract

Key Words: Risk Perception, Biological Risk, Bio-security

Purpose: The aim of this study was to assess the perception of biological risk and compliance with ththe standard bio-security norms of 5 semester students from the dentistry department at the

Universidad El Bosque, sensitized through a communication strategy in 2007 during I, II, III and IV thsemester, and compare the results with those obtained in a previous study with 5 semester

students from the same department during the first period of 2003, who were intervened with an information strategy.Methods For the assessment of perception and compliance with standard bio-security norms, the data were analyzed through focus groups and by observations made during the initial, intermediate and final stages of the previously mentioned periods. Results: When considering risk perception, for students in 2003 risk is centered on social context, while for 2007 students it is focused on the interaction with patients. These observations showed that compliance with biosecurity norms is higher among students intervened with the communication strategy.Conclusions: The change of conduct towards risk is not fulfilled completely through the communication strategy, and it should be redefined in order to achieve more desirable changes of conduct in students.

Abstract

Key Words: Knowledge, lifestyle, oral health education.

Socioeconomically, cultural factors and non-habitual practice of oral hygiene are the main causes that trigger oral pathology. Through synchronous qualitative studies, the habits and oral hygiene practices in the neighborhood “el Níspero” in Monteria, Colombia were carried out. Several surveys, in the order of 259 were carried out. Appropriate habits and practice in oral hygiene were unfamiliar in 59% of the population. Only 48% of the population acknowledged brushing twice a day without proper training on tooth brushing techniques. Use dental floss or mouthwash was not acknowledged. The lack of health care and need of programs of promotion for dental health and prevention in “el Níspero” are the main reasons for such lack of proper information among the population.

Abstract

Key Words: Social representations, maxillary orthopedic, dental occlusion, general health, oral health.

This study tried to recognize the social representations on general health, oral health, occlusal health and maxilar orthopedic treatments of children and their families, who attend to the orthopedic services from the Autonoma de Manizales University and the relation with the professionals' speeches and practices during 2005-2006.The investigation used a qualitative cut methodology, in agreement with the nature of the social representations, it bases the classic school promulgated by Denise Jodelet. In order to collect the information, semi-structured surveys were applied to both children and their families, with the aim of finding out about the representations they have around general health, occlusal health, oral health, bad occlusions and maxillary orthopedic treatments; professionals were interviewed as well, to recognize in their speeches the concepts treated with the children and their families, contrasting this information with the formation of focal groups in the same population groups; a categorical analysis was performed as a method to analyze the information.This information let a breaking of dialogues between the children, families and professionals, after making sure that families recognize oral health as a main component of general health, but they do not recognize occlusal health as a component of oral health, at the same time they make a transversalization of the three levels of health by the functionality and orthopedic treatment.On the other hand, children recognize oral health as much as occlusal health, considering them part of general health; while professionals treat oral health and occlusal health independently when performing maxillary orthopedic treatments. With the aim of presenting a model as a base of the performed interpretation, the general theory of systems is assumed, understanding the human being as a system.

Objective: to evaluate mass media use by university students.Methodology: a descriptive study of a 13,247 student population. Probability sampling had a confidence level of 95% and a 5% margin of error. The sample involved 307 students. Results: 53.4% of the students read magazines, 58.3% read newspapers and periodicals, 93% watch television, 89.5% were connected to the Internet and 67.4% listen to the radio. The most viewed, read or listened to subjects involve violence, entertainment and politics. Health related issues recently viewed, read about or listened to involved child abuse 68%, eating fruits 62% and use of condoms 58.9%. Consulted sources that generated the greatest confidence on general health matters were doctors, family and the Internet; on sexual health matters, sources that generated the greatest confidence were doctors, friends and the Internet. Friends were the most consulted sources on matters involving sexual health, consumption of snuff, psychoactive drugs, alcohol and food. The family was the most frequently consulted source concerning oral health. Of the participants, 34.6% recalled accessing information related to health, of which 39.8% considered such information irrelevant to their lifestyle.Conclusions: health and communication students represent the group most exposed to television, Internet, radio and the press. They use such media information for entertainment and to stay abreast of current events. The health-related information they most recall involves violence, sexual health and healthy diets, which is, to some extent, used to modify their lifestyles.

Abstract

Key Words: School campaign, knowledge, attitudes, practices, beliefs, communitarian IPB, COP-D Index, coe-d Index

The investigation is descriptive longitudinal, it aimed to evaluate the effect of the campaign “Bright smiles, Bright futures) implemented at Nueva Granja Miravalle school” in Santiago de Cali in 2007, by means of three buccodental indicators) (IPBC, COP-D, coe-d) and a survey of the scholars' knowledge, attitudes, practices, beliefs (CACP).58 scholars, ages 7 and 11, from third, fourth and fifth grades, who met the admission criteria, were included. The obtained results were a communal plaque index (IPBC) of 71.6% for the first measurement and 41.9% for the second one, reducing in a 29.7%, which demonstrates that the campaign is achieving positive results. The COP-D registered was 1.22 and the Coe-d was 2.57. In the data from the survey CACP, no significant differences were found between the first and second measurements. We can conclude from the points above that the education campaigns have a preventive effect that improves the hygiene conditions of the target population, unfortunately such effect is not permanent, therefore it is recommended to increase the frequency of the oral health promotion programs to every 6 months, which would help to keep and improve the right practices, as they recognize the protective factors.

This is a descriptive study with a sample of 35 limited visual, in ages between 10 to 62 years, of both sexes of the ALIVMETA Association.The purpose of this study was to design and implement a handbook in a Braille system that could stop handling of the oral hygiene in limited visual people. Assuring an improvement in their oral hygiene and oral diseases are reduced and thus improves their quality of life. Also it is tried to offer information to all those interested people and institutions that benefit the limited visual population through permanent campaigns on oral hygiene. The Meta department has approximately 350 limited visual people, 94 of these people are registered in the Limited Visual Association of Meta (ALIVMETA). This institution does not have a program of oral hygiene education or a didactic material for this purpose. The visual limitation causes that the oral hygiene is reduced by the motor. Due to a deficiency in the dental brush; causing this a high lost degree of dental derivative of periodontal disease. Once designed the handbook and the macro models, three indices of biofilm were made. An initial study and two additional ones taken after the accomplishment from two workshops audio - tactile, giving as a result the reduction of the biofilm to 82%. To conclude, the record of oral hygiene and the designed and implemented didactic material in this study are an effective method of education for the limited visual population.

Abstract

Key Words: Dental fluorosis, prevalence, scholars, fluor, Dean Index, TFI index

Purpose: To compare the levels of dental fluorosis in scholars between the 6 and 17 years old for

two educative institutions of two municipalities of Santander.

Material and methods: An observacional descriptive cross sectional study was done; the universe

and the sample were integrated by the totality of scholars of two educational institutions for two

municipalities of Santander. Sociodemographic variables, systemic conditions, water

consumption, use of fluoride tooth paste, perception of the teeth appearance, dental decay by COP

index and the dental flurosis by Dean and TFI index were collected. The statistic analysis implied

the calculation of summary measures according to the nature of the variables; by bivariate analysis

the municipality was considered like exit variable, for the qualitative variables Chi square and

Fisher Exact test was applied and by the quantitative variables t student and Wilcoxon ranks test

was used.

Abstract

Key Words: Under Rule 6 years of Neuquen Province Relacion Caries / nutritional status

The objective of this work was to describe and to analyze the relation between nutritional state and the process of caries. This investigation I within the framework carry out of the Program “Control of the smaller healthy boy of 6 years” in execution in the Province of Neuquén. Were evaluated the children born in the years: 2002-2003-2004, that is controlled in Valentina Sur Health Center of capital Neuquén. The caries is a disease of multi-factor aetiology, but the diet is one of the most important factors that it determines his appearance. To know if the caries prevalence is greater in some of the 3 nutritional states studied is substantial part of the process to begin to solve it and better to even prevent it, since it will allow to identify a group of greater cariogenic risk where they will be able to be accentuated or to prioritize the preventive actions and curative, at the time of organizing the activities that are developed in center of Health. The released information was extracted of secondary sources (HC) and in its analysis it is observed: - 72% of the evaluated children presented caries of different gravity. - The prevalent nutritional state is the one of eutróficos children, but the type of malnutrition that predominates is overweight, on the undernourishment. - The nutritional state Eutrófico implies a type of exhibition that has strong chance to develop caries. However in the Overweight there is a moderate possibility of developing caries. But without a doubt, in the undernourishment the maximum prevalence of caries is observed.

Materials and methods: A descriptive observational study was done on a population of 42 selected for convenience. As selection criteria dentists doing their clinical practice and without any musculoskeletal alterations (due to trauma or of congenital origin) were taken into account. The variables were age, gender, time, job characteristics, physical activity, postural ergonomic risk and musculoskeletal symptoms, the REBA index was performed by means of direct observation for 10 minutes for the ergonomic risk and the Nordic Scandinavian questionnaire was applied for the musculoskeletal symptoms.Results: 54.8% (n = 23) of dentists have presented some form of discomfort on the neck, 57% on the back, 26% on the hands and wrists. The postural ergonomic index, REBA, had a value of between 7 and 12, which ranks it in a mid- to-high level. Significant difference was found between ergonomic risk and musculoskeletal symptoms at the neck level (p=0,030Conclusions: There is a high prevalence of musculoskeletal disorders on the back, neck and upper limb of dentists. The level of postural ergonomic risk (REBA) is medium to high which indicates a necessary and early intervention. There was significant statistical relationship between risk and ergonomic musculoskeletal disorders at the neck. Dentist's musculoskeletal problems do not cause absenteeism at work.
