A rare clinical phenomenon of four rooted maxillary second molar: A case report

Abstract

Adequate knowledge about the morphology of root canal system is elementary for successful endodontic treatment. Maxillary second molars usually present with clinical morphology of two buccal and one palatal root. Occurrence of an extra palatal root is a rare scenario and least documented. The following case report describes successful non-surgical management of maxillary second molar with an unusual morphology of two independent palatal roots. The access cavity design was modified as dictated by the internal anatomy of the tooth and the chemo-mechanical preparation of root canals was done using rotary NiTi files and obturated using resin sealer.
