Endodontic management of Type III dens invaginatus with the aid of cone-beam computed tomography

Dens invaginatus (DI) is a rare developmental anomaly characterized by invagination of the enamel organ into the dental papilla before calcification has occurred. Maxillary lateral incisor is most commonly involved. The complex anatomy of this anomaly presents as a major challenge to the endodontist. The two-dimensional imaging such as intraoral periapical radiographs and bitewing fall short of defining the extent of the defect. The three-dimensional extent of this lesion can be visualized efficiently using a cone-beam computed tomography, which can help in a better understanding and treatment planning. Depending on the extent of the DI, the treatment modalities can be either surgical or nonsurgical. The present case highlights a maxillary central incisor with Type III DI which was managed using contemporary endodontic techniques.
