Abstract

Aim

To report the treatment of an unusual combination of one dens evaginatus and two dens invaginatus in a single tooth and its healing outcome after 10 years.

Summary

The long-term outcome of a maxillary lateral incisor with dens evaginatus combined with two Oehlers type II dens invaginatus and a large periradicular lesion in an 11-year-old female treated endodontically and restoratively is described. The endodontic treatment included intracanal medication with calcium hydroxide and canal filling using a thermoplastic root canal filling technique. The crown was restored with conventional composite resin. During periodic clinical and radiographic follow-up, the patient remained symptom free, and the periradicular region was completely healed, meeting both aesthetic and functional expectations after 10 years.

Key learning points

  • The co-occurrence of dens evaginatus and two dens invaginatus in the same tooth is an unusual finding that compromises aesthetics and predisposes the patient to dental pulp infection.
  • The complex morphology observed in this case represented both endodontic and restorative challenges.
