Abstract

Dens in dente are a growth disorder caused by the inversion of the coronary tissue into the pulp chamber before mineralization. It can be constrained to the crown or extent the root and influence the periapical area.
The condition seen in the radiographic image is usually 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 reveal pulp necrosis and open apex, which may bring about some challenges to manage it. Early detection of the malformation is critical for better handling and makes treatment plans more conservative, like restorative procedures.
We described the management of an uncommon case of type III dens in dente diagnosed using a cone-beam CT scan in a maxillary lateral incisor. The patient had a chronic periapical lesion, a buccal sinus tract, and palatal expansion, which were healed successfully after treating with non-surgical root canal procedure.
