Dens invaginatus: A report of two cases

Abstract

Dens invaginatus is an uncommon developmental anomaly of teeth arising due to the invagination of the dental papilla. The affected teeth show an infolding of enamel and dentine even sometimes extending into the root causing perforation. The malformation exhibits a wide variety of presentation. On the other hand, it can affect any teeth including primary, permanent and supernumerary teeth. The frequently affected teeth are maxillary lateral incisors. It usually results in pulpal necrosis when the invagination is extending into the pulp chamber. In most cases, it is diagnosed as an incidental finding in a routine dental examination as an alteration of the crown structure or as a radiographic finding. An early prophylactic approach is the most effective means of treatment. However, endodontic management of the affected tooth is often required.
