Endodontic management of a mandibular second premolar with three canals using cone beam computed tomography-case report

A thorough knowledge of root canal anatomy along with the anatomical variations that may be present is essential for success of endodontic therapy. Unusual presentations in the number of the roots or the canals should be expected in every tooth. Mandibular second premolars are thought of as having a single root and canal. Studies have stated that the prevalence of three canals with three orifices in this tooth is 0.4% Knowledge of variations in root canal anatomy and accurate diagnosis with novel diagnostic aids like cone beam computed tomography (CBCT) assist in thorough debridement and three dimensional obturation of the root canal system, thus increasing the success rate of nonsurgical endodontic treatment. This article describes the successful management of the right mandibular second premolar with three separate roots diagnosed using CBCT.
