A clinical and radiographic evaluation of treatment effectiveness in a case of chronic apical periodontitis with furcation involvement: case report

This case report describes the successful endodontic management of an 18-year-old male patient diagnosed with chronic apical periodontitis accompanied by isolated bone destruction in both the apical and furcation regions of mandibular molar #46. The patient presented with mild masticatory discomfort, a nonvital pulp, and radiolucencies detected in the furcation and periapical areas. Root canal treatment was performed using rotary instrumentation. This case underscores the role of meticulous chemomechanical preparation, irrigant activation, and coronal sealing in achieving predictable healing even in complex anatomical conditions involving accessory and interradicular canals. Early identification of these anatomic features and adherence to comprehensive endodontic protocols significantly enhance long-term treatment outcomes.
