C-shaped single canaled mandibular second molar: A rare case report

Abstract

This case report presents a rare root canal system in a mandibular second molar tooth, a single root with a single canal. C-shaped canals with varying configuration are commonly observed in single-rooted mandibular second molars. The access cavity displayed only one round/oval canal orifice which is very rare. The knowledge of dental anatomy is an essential tool for the success of endodontic treatment. The early recognition of these configurations facilitates cleaning, shaping, and obturation of the root canal system. Therefore, a clinician thus requires to have adequate knowledge about root morphology and its variation. Thorough knowledge of the root canal anatomy is necessary to perform a successful endodontic treatment.
