Surgical Retreatment with Esthetic Rehabilitation – A Case Report

Abstract Clinicians often face challenges during treatment that may lead to failure. Like other dental procedures, endodontics is not exempt from setbacks. Common causes include improper mechanical debridement, residual bacteria in the canals and apex, suboptimal obturation quality, incorrect root canal filling length (over or under extension), and coronal leakage. Although endodontic treatments generally have a high success rate, failures still occur frequently due to these factors. Likewise, Endodontic re -surgery is required to manage unresolved infections or new pathological changes, particularly in cases where the primary treatment did not fully eliminate the problem.
