Endodontic management of type IIIB dens invaginatus: An unusual case report

Abstract

Dens invaginatus (DI) is an unusual anomaly of teeth, presumably resulting from an infolding of the dental papilla during tooth development. The root canal treatment of such teeth is arduous because of problems associated with gaining access to the root canals and with variations of canal morphology associated with this type of malformation. The present case describes the effective endodontic treatment of an Oehlers Type IIIB DI in a mandibular right central incisor associated with periapical lesion. It likewise demonstrates that spiral computed tomography scan is a significant auxiliary aid to avoid errors in diagnosis and treatment of the dental anomaly
