Endodontic management of double dens invaginatus in maxillary central incisor.

This case report deals with the successful endodontic treatment of double dens invaginatus in maxillary left central incisor. Dens invaginatus is a rare developmental anomaly that is challenging to diagnose and treat. A patient reported with unesthetic appearance and previously attempted endodontic treatment of tooth #21. Cone beam computed tomography revealed the presence of a complex invagination communicating with the periodontium. A combination of techniques enhanced the debridement of the complex invagination. Obturation was performed using warm vertical compaction. The patient was asymptomatic during the follow-up period of 12 months.
