Abstract :

Any attempt to perform endodontic therapy must be preceded with a thorough understanding the anatomy of both pulp chamber and the root canal system after by using cle� technique. A thorough knowledge of root canal morphology is essential for successful endodontic therapy. This study is be conducted on extracted mandibular second molars from north Indian population of Himachal Pradesh. AIM of this study is : To investigate number of roots and root canals. Methodology: A total of 100 mandibular second molar extracted over a period of two years were selected for study. Endodontic access cavities were prepared, patency of canals were checked and the pulp tissue was removed by immersing teeth in sodium hypochlorite for 2 days. Teeth were decalcified, then dehydrated and were then made transparent by immersing samples in methyl salicylate solution. Cleared specimens were observed using magnifying lens at 5X magnification. They were looked for number of roots and root canals. Results: The majority of mandibular molars Majority of second permanent mandibular molars had two separate roots (88%). The order of occurrence of number of canals was 3 canals (55%)˃ 2 canals 24 % ˃ 4 canals (18%) ˃5 canals (2%)˃ 1 canal (1%). Conclusion: Staining and cle� technique is an effective measure for the evaluation of root canal configuration without altering the canal configuration.
