Ushanthika T, Surendar S

Introduction: The endodontic re-treatment demand is increased, because the observations of numerous cross-sectional studies showed that an increased percentage of root filled teeth have evidence of apical periodontitis radiographically and other major reasons that can lead to re-treatment. Aim: The aim of the present study was to assess the reason for retreatment of endodontically treated teeth. Materials and Methods: A Retrospective analysis of all the cases who underwent retreatment was taken and the reasons were assessed. The data was retrieved among the overall data of patients visiting Saveetha Dental College from June 2019-March 2020. The data for 210 patients who underwent retreatment was entered in Excel Spreadsheets and the collected data was analysed using SPSS software version 19. Chi square test was used to statistically evaluate the results. Results: The results of this study show that the main cause of retreatment is incomplete obturation (53.81%), (28.57%) of retreatment is caused due to lesion and periapical pathology, (3.33%) is due missed canals, (10.95%) is due to symptomatic RCT and 3.33% is due to other reasons. The chi-square test was done between age and reason for retreatment and was found to be significant (p value=0.001<0.05; statistically significant). Conclusion Within the limitations of the current study, in this study the main reason for endodontic retreatment were incomplete root canals obturation followed by lesions.
