Learning Objectives
Understand the diagnosing criteria for periodontal case types
Discover how risk factors, host modulation therapy and genetics play a role in treating patients with periodontitis
Realize why the “gold standard” of non-surgical periodontal therapy is still based on the complete removal of the subgingival bacterial bioburden
Learn clearly defined treatment protocols using “Anti-Infective Agents” to decrease the incidence of disease recurrence

“The effectiveness of subgingival scaling and root
planing in calculus removal” Rabbani, Ash, Caffesse

effective SRP
pockets between 3 to 5mm were more difficult to remove calculus and biofilm
pockets deeper than 5mm were the most difficult …tooth type didn’t influence the results

3 Things To Know Before Beginning Any Periodontal Therapy:
• Objectives
• Limitations
• Expected Results
![Page 27: 2014 National Primary Oral Health Conference · “Sub antimicrobial dose” antibiotic—does not cause Abx resistance 20mg Doxycycline 2x daily taken on an empty stomach . Genetics](https://reader036.vdocuments.site/reader036/viewer/2022071102/5fdbc6a6a6f3200e2218eb10/html5/thumbnails/27.jpg)
Objectives of Treatment
Interrupt the disease process to resolve (and or mediate) the infection and or inflammation
Reduce Risk
Maintain or regenerate periodontal/peri-implant support
Expect treatment to resolve or reduce the periodontal inflammatory disease
![Page 28: 2014 National Primary Oral Health Conference · “Sub antimicrobial dose” antibiotic—does not cause Abx resistance 20mg Doxycycline 2x daily taken on an empty stomach . Genetics](https://reader036.vdocuments.site/reader036/viewer/2022071102/5fdbc6a6a6f3200e2218eb10/html5/thumbnails/28.jpg)
Treatment Variables
• Patient responsibility (OH, co-pay,)
• Limitations:
Tooth and root anatomy
Severity of the periodontal disease
Risk
Operator (the clinician)
• Expected results are not met

Risk Factor Management
Objective
minimize the pathological factors
maximize the protective factors
to favor prevention
reverse or arrest disease

When combined Risk and Disease:
Are distinct entities that provide a more comprehensive description of health status

Risk: guides preventive treatment or
an action plan modulates treatment intensity
and aggressiveness

Periodontal Inflammation
• Yesterday: Researchers believed that attachment loss in periodontal disease was caused by the bacteria in plaque
• Today: Researchers have determined that attachment loss in periodontal disease is caused by the inflammatory response to the bacteria in plaque

Genetics Role
• On a hereditary level, not everyone is genetically susceptible to periodontitis.
• Specific genetic markers associated with increased IL-1 production are “a strong indicator of susceptibility to severe periodontitis in adults”
![Page 48: 2014 National Primary Oral Health Conference · “Sub antimicrobial dose” antibiotic—does not cause Abx resistance 20mg Doxycycline 2x daily taken on an empty stomach . Genetics](https://reader036.vdocuments.site/reader036/viewer/2022071102/5fdbc6a6a6f3200e2218eb10/html5/thumbnails/48.jpg)
Interleukin-1 genotype
People with the IL 1 are 7X more likely to develop advanced perio than the general population
This genotype occurs in 30% of the population

SRP for the disruption and removal of subgingival bio-burden continues to be the “gold standard” of non-
surgical periodontal therapy regardless of what adjuncts are used

5 Critical Steps for Improving Patient Outcomes
1. Make an accurate diagnosis 2. Schedule appropriate time commensurate to the level of
disease and use anesthetic 3. Concentrate on root morphology while instrumenting 4. Use anti-infective agents in therapy and OH to decrease the
incidence of disease recurrence
5. Love what you are doing and let it show
