Nonsurgical endodontic treatment of a maxillary lateral incisor with dens invaginatus type II: A case report
Abstract
Dens invaginatus is a rare developmental anomaly of teeth with complex root canal system
morphology. The present case describes a peg shape maxillary lateral incisor with dens invaginatus
(Oehlers type II), necrotic pulp, and an associated large periradicular lesion. Nonsurgical endodontic
treatment was performed with the aim of removing the blind sac with diamond bur under the use of
operating surgical microscope. The root canal system was obturated with thermoplastic technique.
Final restoration was done using composite. The 20-months clinical and radiological follow up
revealed an asymptomatic tooth with healing of the periapical pathology; however, for complete
healed periradicular lesion more follow up is needed. This case illustrated that a dens invaginatus
malformed teeth with a large periradicular lesion can be managed successfully with nonsurgical root
canal therapy (NSRCT).
