Do insucesso endodôntico ao êxito clínico: um relato de caso

Abstract

The success of endodontic treatment is directly related to proper technical execution and effective infection control within the root canal system (RCS). However, failures can occur, and one of the parameters for evaluating the quality of endodontic treatment is the lack of proper compaction of the filling material, which may be associated with intracanal reinfection. In such cases, non-surgical endodontic retreatment represents the primary alternative to correct poorly performed previous interventions. This study aims to report a clinical case of a patient who attended the Dentistry Department at the Federal University of Sergipe (DOD-UFS), presenting with unsatisfactory obturation of tooth 11. As a therapeutic approach, non-surgical endodontic retreatment of tooth 11 was performed, involving mechanical removal of the filling material using a nickel- titanium rotary file system, manual instrumentation, active irrigation, intracanal medication, and new obturation. The clinical protocol followed the recommendations of the specialized literature, with emphasis on effective disinfection of the RCS and adequate root sealing. A satisfactory retreatment was achieved, with the final periapical image showing well-compacted gutta-percha, resulting in an improved quality of obturation compared to the previous treatment. It is concluded that non- surgical endodontic retreatment proved to be effective in cases of poorly compacted root fillings, highlighting the importance of using evidence-based techniques.
