title: Cone-Beam Computed Tomography-Guided Management of C-Shaped Type III Dens Invaginatus With Peri-invagination Periodontitis in a Maxillary Canine: A Case Report.
abstract: Dens invaginatus (DI) is a developmental anomaly seen infrequently in maxillary canines. This article describes cone-beam computed tomography-guided nonsurgical management of type III (subtype B) DI in a permanent maxillary canine associated with a sinus tract and peri-invagination periodontitis in a 17-year-old female. After gaining access to the root canal, thorough chemo-mechanical preparation was performed and usage of intracanal medicament of calcium hydroxide was prescribed for 3 weeks, during which the sinus tract healed completely. Obturation was completed by a technique of down-packing master-cone gutta-percha, followed by backfilling with thermoplasticized gutta-percha. At 12-months follow-up, the patient was asymptomatic with complete resolution of the sinus tract and radiographic evidence of healing of periapical pathology.
