Q.1:- WHAT IS ROOT CANAL TREATMENT ?

‰..ROOT CANAL TREATMENT (ALSO KNOWN AS ENDODONTIC TREATMENT) IS THE PROCESS WHERE THE DENTIST REMOVESTHE PULP. i.e. PULP EXTIRPATION. FROM AN INFECTEDTOOTH AND REPLACES IT WITH DENTAL FILLING.

‰..ROOT CANAL TREATMENT IS ALSO NECESSARY IF THE TOOTH HAS LOST IT’S VITALITY[DIED] BUT GENERALLY IS BECAUSE DECAY HAS PENETRATED BOTH THE ENAMEL AND DENTIN TO THE CENTRE OF THETOOTH AND IT MAY CAUSE AN ABSCESS ALSO.

‰..IF YOU DON’T WANT YOUR TOOTH TO BE ROOT FILLED THAN THE ALTERNATIVE IS USUALLY AN EXTRACTION.

Q.2:-WHY WOULD YOU NEED ROOT CANAL TREATMENT ?

‰..ROOT CANAL TREATMENT IS NEEDED FOR FOLLOWING REASONS:INFECTION OR IRREVERSIBLE DAMAGE. AN UNTREATED CAVITYIS A COMMON CAUSE OF PULP INFECTION.THE REDUCED BLOODSUPPLY ALSO LIMITS THE PULP’S ABILITY TO HEAL ITSELF.

‰..THE PULP CAN BECOME DAMAGED FROM TRAUMA, OR FACTURE OVER A PERIOD OF TIME.

‰..ONCE THE PULP BECOME INFECTED,THE INFECTION CAN SPREAD TO THE BONE AROUND THE TOOTH, ABSCESS TO FORMIF THE RCT IS NOT DONE,THE TOOTH MAY HAVE TO BE EXTRACTED,BUT THE BONE STILL MAY HAVE TO BE TREATED.

‰..IF AN INFECTED TOOTH THAT NEEDS RCT IS IGNORED, NOT ONLY CAN U LOOSE THE TOOTH. BUT ALSO INFECTION CANSPREAD TO OTHER PARTS OF UR BODY.

‰..AN INFECTION IN THE ROOT CANAL OF A TOOTH CAN CAUSE…

‰..A SWELLING WITH PUS IN THE AREA AROUND THE TOOTH ROOT

‰..A SWELLING THAT MAY SPREAD TO OTHER AREAS OF THE FACE

‰..BONE LOSS AROUND THE TIP OF THE ROOT OF THE TOOTH

‰..A DRAIN HOLE (CALLED A SINUS) BETWEEN THE ROOT OF THE INFECTED TOOTH AND OUTSIDE CAN BE THGH THE SIDE OF THE TOOTH INTO THE PERIODONTIUM.

Q.3:- WHY DO WE FEEL PAIN BEFORE ROOT CANAL TREATMENT ?

Q.4:- SIGNS AND SYMPTOMS ?

‰..IF U’VE AN INFECTION OF THE PULP, U MAY NOT FEEL ANY PAINAT FIRST. BUT IF LEFT UNTREATED INFECTION’LL CAUSE PAIN ANDSWELLING. IN SOME CASES, AN ABSCESS WILL FORM. EVENTUALLYTOOTH NEED TO BE EXTRACTED.SOME INDICATIONS THAT A TOOTHMAY NEED A ROOT CANAL TREATMENT R:

‰..A TOOTH THAT HURTS SIGNIFICANTLY WHEN U BITE DOWN ON IT, TOUCH IT OR PUSH ON IT.

‰..SENSITIVITY TO HEAT.

‰..SENSITIVITY TO COLD THAT LASTS LONGER THEN A COUPLEOF SECONDS.

‰..FACIAL SWELLING NEAR THE AFFECTED TOOTH.

‰..A DISCOLORED TOOTH, WITH OR WITHOUT ACCOMPANYING PAIN.

Q.5:- HOW DOES THE PULP GET INFECTED ?

‰..SOMETIMES THE PULP INSIDE UR TEETH BECOMES INFLAMEDOR INFECTED.

‰..THIS CAN BE CAUSED BY DEEP DECAY, REPEATED DENTALPROCEDURES ON THE TOOTH, A CRACK OR CHIP ON THE TOOTH,OR A BLOW TO THE TOOTH. THE MOST COMMON CAUSE IS TOOTH DECAY.

‰..TOOTH DECAY IF LEFT UNTREATED SPREADS TO PULP THEN IT BEGINS TO DEGENETRATE.

‰..AS WITH ANY INFECTION THERE IS FORMATION OF PUS,WHICH TENDS TO GET ACCUMULATED AT TIP OF ROOTS WITHINTHE JAWBONE, FORMING A “PUS-POCKET” CALLED AN ABSCESS.

Q.6:- WHAT HAPPENS WHEN A PULP GETS INFECTED ?

Q.7:- HOW IS ROOT CANAL TREATMENT DONE ?

‰..FIRST AN OPENING IS MADE THGH THE OCCLUSAL AREA OFPOSTERIOR TEETH AND CINGULUM OF ANTERIOR TEETH.

‰..IF MORE THAN ONE VISIT IS NEEDED, A TEMPORARY FILLINGIS PLACED IN THE OPENING OF THE TOOTH.

‰..AFTER THE DISEASED PULP IS REMOVED, THE PULP CHAMBER& ROOT CANAL IS ENLARGED & SHAPED IN PREPARATION FOR BEING FILLED.

‰..THE TEMPORARY FILLING IS REMOVED AND THE PULP CHAMBER& ROOT CANAL PERMANENT RESTORATION IS TAPERED, SOMETIMEA METAL OR PLASTIC ROD IS PLACED IN THE CANAL FOR SUPPORT.THIS ROD IS CALLED POST.

‰..IN FINAL STEP, A CROWN IS USUALLY PLACED OVER THE TOOTH TO RESTORE ITS NATURAL SHINY APPERANCE. IF THE TOOTH IS MUCH BROKEN, A POST MAY BE REQUIREDTO BE BUILD UNDER THE CROWN.

‰..ALL RCT PROCEDURES R DONE BY ISOLATING THE TOOTHWITH A RUBBER DAM TO PROVIDE SALIVA-FREE ENVIRONMENT.RCT MAY BE DONE IN SINGLE OR MULTIPLE VISITS DEPENDING ON COMPLEXITY OF THE TOOTH.

‰..OFTEN..,X-RAYS R TAKEN TO DETERMINE THE LENGTH OFTHE ROOT & TO MONITOR THE VARIOUS ASPECTS OF TREATMENT.

1.PULP DAMAGE

THE MOST COMMON WAYFOR THE PULP TO BECOME

INFECTED IS FROM ANUNTREATES CAVITIES

THAT CONTAINS BACTERIAWHICH RELEASES ACID.THAT

CAUSE PULP DAMAGE.

2.PULP REMOVAL

PULP IS REMOVED BYBARBED BROUCHES.

3. REMOVING THE INFECTED TISSUE.

SPECIAL FILES R USEDTO CLEAN THE INFECTION& UNHEALTHY PULP OUT OF THE CANALS. IRRIGATIONIS USED TO CLEAN SMALL OFFSHOOTS OF MAIN CANALCALLED LATERAL CANAL.

4. FILLING THE CANALS.

THE CANALS R FILLED WITHA PERMANENT MATERIAL GUTTA-PERCHA. THIS HELPS TO SAVETOOTH & KEEP THE CANALSFREE OF THE CONTAMINATION.A THIN, METAL INSTRUMENTPLUGGER, IS USED TO PUSH THE GUTTA-PERCHA IN CANALSSO THAT IT BECOMES COMPACT

5.REBUILDING THE TOOTH

A TEMPORARY FILLING MATERIALIS PLACED ON TOP OF THE GUTTA-PERCHA TO SEAL THE OPENING UNTILTHE TOOTH IS READY TO BE PREPAREDFOR A CROWN. A CROWN, SOMETIMESCALLED CAP, IS MADE TO LOOK LIKEA NATURAL TOOTH, AND IS PLACEDON TOP.

Q.8:- HOW LONG IS THE TOOTH LIKELY TO LAST AFTER IT IS ROOT FILLED ?

‰..ROOT FILLED TEETH OFTEN LAST FOR MANY YEARS. IT IS,HOWEVER, VERY DIFFICULT FOR A DENTIST TO COMPLETELY ERADICATE THE INFECTION INSIDE THE TOOTH. AS A RESULT,IT IS IMPOSSIBLE TO GUARANTEE THAT THE TOOTH WILL SURVIVE FOR A PARTICULAR LENGTH OF LENGTH OF TIME.

‰..IN ANY EVENT, THE LIFE EXPECTANCY OF ANY TOOTH ISN’TENTIRELY DOWN TO UR DENTIST, BUT IS GREATLY INFLUENCED BY FACTORS UNDER UR OWN CONTROL, SUCH AS UR DIET & HOWWELL U LOOK AFTER UR TEETH.

‰..IF THE INFECTION COMES BACK IT IS OFTEN POSSIBLE FOR UR DENTIST TO REPEAT THE RCT TO GET RID OF THE INFECTIONAGAIN & AVOID EXTRACTING THE TOOTH.
