Endodontic management of mandibular second premolar with three canals

Abstract

Knowledge of root canal morphology has been a complex and utmost important issue regarding the planning and implementation of root canal therapy. In addition to having adequate knowledge on periapical radiographs from different angles, careful examination of pulp chamber floor and the use of technological advances are also salient factors that contribute to the diagnosis of additional roots and canals. The occurrence of three canals with three separate (Type V, Vertucci) foramina in mandibular premolars is very rare. This article reports and discusses the treatment for an atypical occurrence of three canals with three separate foramina in the mandibular second premolar.
