first phase-diagnostic phase-in which the disease to be treated, is determined and treatment plan developed.
second phase-preparatory phase-when the contents of the root canal are removed and the canal prepared for the filling material.
third phase-involve filling or obliterating canal to gain hermetic seal with an inert material as close as possible to cementodentinal junction.
3] Importance of debridement
Endodontic is essentially a debridement procedure that require the removal of the irritants of the canal and periapical tissue if success is to be gained.
Debridement may be required in various ways:
1] instrumentation of the canal
2] placement of the medicament
3] irrigant
4] electrolysis
5] surgery
4] Use of rubber dam is mandatory
5] Great respect due the periapical tissue during treatment
6] Proper restoration the culmination of success
7] Postoperative observation necessary
8] Case presentation to set the stage
