Endodontic Management of a Three Rooted Mandibular Third Molar with a Dilacerated Distal Root and Close Approximation to the Inferior Alveolar Canal: A Case Report

Abstract

Aim: A thorough understanding of root and canal anatomical variations is essential for achieving successful endodontic treatment. Literature continues to demonstrate complex root and canal anatomical variations in mandibular third molars which are sometimes in close approximation to the inferior alveolar canal.

Methodology: A 26-year-old male patient was referred for endodontic treatment of a three-rooted mandibular third molar with a dilacerated distal root and close approximation to the inferior alveolar canal. A cone beam computed tomography was performed to assess the root and canal anatomical variations together with the inferior alveolar canal. Conventional endodontic treatment was performed using a rotary nickel-titanium file system, and the canals were then obturated using a cold lateral condensation technique.

Results: The endodontic treatment procedures were performed successfully and in the follow-up visit, the tooth was asymptomatic.

Conclusions: Despite limited accessibility and challenges during root canal treatment procedures, retaining every functional component of the dental arch, including mandibular third molars, is an essential goal of contemporary dental practice.
