title: Complex treatment of dens invaginatus type III in maxillary lateral incisor.
abstract: The complex anatomy and diagnosis of dens invaginatus make endodontic treatment of such teeth difficult. This case describes combined nonsurgical and surgical treatment of a maxillary lateral incisor with a normally shaped canal and a dens invaginatus type III with a lateroradicular lesion. The root canal was treated conventionally with gutta-percha and a zinc oxide-eugenol sealer. The root was surgically exposed and the canal of the dens invaginatus was cleaned, instrumented and obturated with gutta-percha and a zinc oxide-eugenol sealer. At follow-up 3 years 6 months later, the tooth was asymptomatic and radiographically showed repair of the lesion in the region of the dens invaginatus.
