Introduction: Root canal treatment is one of the most commonly performed procedures in a dental office. It is aimed at removing the entire pulpal tissue, debris and microbes and creating a three dimensional fluid impervious seal of the root canal. The failure of root canal treatment can occur due to a number of reasons like under filling, missed canals, overextended obturation, persistent lesion, etc. Overextended obturation irritates the periapical tissues leading to periapical lesion and possible cystic transformation. Aim: To find out the radiographic assessment of Obturation length in cases presenting for the retreatment. Materials and Methods: A total of 1054 patients who had undergone re-RCT were included in the study. The collected data was subjected to data analysis. Results and Discussion: 18-40 (64.86%) years is the most common age group that has undergone the retreatment ; males (58.97%) are the most common gender who have undergone retreatment; maxillary anterior teeth (38.56%) are the most common teeth that has undergone retreatment; Majority of the patients presented with under filled root canal (>2mm short of the apex) 95.34% (n=1003); Majority of the RE-RCT was done with H files 43.96% (n=462); p value: 0.519 (>0.05) hence not statistically significant, proving that there is no significant association between radiographic obturation length and teeth region; p value: 0.401 (>0.05) hence not statistically significant, proving that there is no significant association between radiographic obturation length and age groups. Conclusion: The present study suggests that vital bleaching has proven to produce satisfactory clinical aesthetic outcome. This study will shed light for future studies that study an even larger population prospective RCTs are needed to further support our evidence.
