Endodontic Management of Mandibular Second Molar with Single Root and Root Canal

Abstract

Root canal anatomy of a particular tooth may show different types of variations. Thorough knowledge of such variations is essential for favourable outcome of root canal therapy. Mandibular second molar usually has two roots and three or four root canals. The anatomical variations commonly encountered in mandibular second molar include single root canal, two root canals, five or more root canals and C-shaped canal configuration. This case report describes the endodontic management of a mandibular second molar with single root and single root canal, which is a rare occurrence.
