Dens Invaginatus with Palatal Expansion and Buccal Sinus Tract: A Case Report

Dens in dente is known as a growth disorder caused by inversion of the coronary tissue into the pulp chamber prior to mineralization; it can be constrained to the crown or extent the root and influence the periapical area. The condition seen in radiographic image like a tooth within a tooth. Although it happens rarely, it is the most frequent malformation detected in human dentition. It can be specially observed in maxillary lateral and then central incisors. Because of the complexity as well as strange anatomy, the tooth has the potential to show pulp necrosis and open apex, which may bring about some challenges to manage it. An early detection of the malformation is critical for better handling and makes treatment plan more conservative like restorative procedures. We describe the management of an uncommon case of type III dens in dente diagnosed using cone-beam CT scan in a maxillary lateral incisor, having a chronic periapical lesion, buccal sinus tract as well as palatal expansion healed successfully after treating with non-surgical root canal procedure.
