Endodontic treatment of immature tooth with dens invaginatus: a case report.

The endodontic treatment of a dens invaginatus in an immature permanent upper lateral incisor of a 9-year-old boy is presented. Root canal treatment was performed using calcium hydroxide paste as a temporary root canal filling in order to achieve apexification. This was replaced after closure of the apex with a final root canal filling using gutta-percha and AH 26 as the sealer. The follow-up radiographic control demonstrated the effectiveness of nonsurgical treatment in a case of incomplete root formation in a tooth with dens invaginatus.
