A maxillary second molar with an unusually positioned root and canal systems

Abstract

Variations in the root canal anatomy can occur in any tooth, if not identified and treated accordingly; they may lead to endodontic treatment failure. A typical maxillary second molar usually has three separate roots with one canal in each. The present case report elucidates the successful endodontic treatment of a rare and unusual root canal anatomy of maxillary left second molar using cone-beam computed tomography as a diagnostic aid.
