Management of single C-shaped canal in mandibular second molar: A case report

Variation in root canal morphology presents a continuous challenge to endodontic diagnosis and treatment. A number of cases have been reported with extra roots and canals, and also those with lesser number of roots and canals than normal. Hence, a clinician must also be aware regarding lesser number of root and canals as existing morphologic variation since varied canal anatomy poses a challenge to the clinician’s expertise. This case report presents a case with the management of an unusual C-shaped canal in mandibular second molar with two buccal roots fused. To confirm the extension of the unusual anatomy, cone-beam computed tomography was employed.
