Endodontic Management of a Mandibular First Molar with Four Individual Canals Evaluated Using Cone-Beam Computed Tomography Scanning

Endodontic management of a permanent mandibular molar is challenging owing to its varied morphology and complexity of the roots and root canal system. A thorough knowledge of the root canal systems and their possible variations is of utmost importance in order to reduce the incidence of endodontic failures caused by missed canals, incomplete debridement, and obturation. The most common presentation of a permanent mandibular molar is one mesial root having two canals and one distal root having one or two canals. The present case report describes the diagnosis and nonsurgical endodontic management of a case of permanent mandibular molar having four roots, each having a single canal. Angled periapical radiograph along with cone-beam computed tomography was used for the identification of roots and root canal system.
