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).
