Root canal system anatomy plays a significant role in endodontic success and failures. Several explanations for failure of root canal treatment have been proposed, including apical percolation, root perforation, unfilled canals, coexisting periodontal lesions, and gross over and underextension of filling materials. Endodontic retreatment is indicated when the root canal system becomes re-infected. Before commencing with any treatment, it is wise to fully consider all the various treatment options. Nonsurgical retreatment is often considered the treatment of choice if a previously treated tooth has persistent apical infections. 86000 patient records were reviewed between June 2019 to March 2020. A total of 269 patients who underwent endodontic retreatment procedures were reviewed and analyzed. The collected data was tabulated using microsoft excel and analyzed using SPSS. Incomplete data was excluded from the study. Statistical analysis was done in SPSS using chi-square test. Association between age and teeth that had undergone endodontic retreatment procedures showed that patients in the age group below 30 years were most commonly involved and the teeth involved were upper anterior (21.56%). Patients belonging to the age group above 60 years were least commonly involved in retreatment procedures (0.37%) (p<0.05). Association between gender and teeth that had undergone retreatment showed that males had undergone a higher number of endodontic retreatment procedures when compared to females and teeth commonly involved were upper anterior (27.85%) (p<0.05) and the least being lower anterior in females (1.12%).
