Retreatment of Overextended Root Canal Filling Using H-File

Abstract Overextended root canal fillings beyond the apical foramen can lead to persistent symptoms and periapical inflammation. This article discusses a retreatment case involving a maxillary anterior tooth, where the previous gutta-percha obturation was extended beyond the apex. The case was managed using H-file mechanical removal and obturation with bioceramic putty. Radiographic images demonstrate pre- and post-treatment conditions with clear clinical resolution. Introduction Root canal obturation should ideally terminate at the apical constriction, not beyond it. Overfilling into the periapical area may provoke foreign body reactions, chronic inflammation, and delayed healing. In cases where gutta-percha has passed beyond the foramen, retreatment is required to remove the extruded material and re-seal the canal at the correct working length. Discussion 1. Causes…
