A unique approach to the treatment of a tooth with dens invaginatus.

Abstract

A case of dens invaginatus in a right maxillary lateral incisor is presented in which a unique treatment was performed. The patient presented with localized swelling and a sinus tract. A mid-root lateral radiolucency was also present. In relationship to both the sinus tract and radiolucency, an accessory root canal was found. It was unrelated to the primary root canal. The accessory canal was first treated with nonsurgical endodontic therapy. Subsequently, surgery was required to overcome the deleterious clinical manifestations. Five years later, neither the swelling nor the sinus tract had reappeared. However, a small radiolucency persisted, which may have been a fibrous scar.
