Abstract - This report describes non-surgical endodontic treatment of Oehlers' type III dens invaginatus in a maxillary lateral incisor with the aid of postobturation cone-beam computed tomography (CBCT). The endodontic treatment was initiated with the aid of a surgical operating microscope, and two canals, one of which represented the invagination, were instrumented, irrigated under passive ultrasonic activation and obturated with the lateral condensation technique. As postobturation periapical radiographs suggested the presence of untereated and/or unfilled areas in the root canal and invagination, CBCT was taken to assess the possibility of further treatment. The CBCT scans demonstrated inaccessible and unfilled canal and invagination areas because of complex internal morphology characterized by (i) C- or ring-shaped cross-sectional canal configuration with constrictions at different points in different root levels and (ii) a prominent intraradicular cavity that was communicated with the enamel-lined invagination and opened into the apical periodontium. Thus, it was judged that further endodontic treatment was not feasible. A 14-month follow-up revealed a satisfactory clinical and radiographic outcome, suggesting that the chemomechanical debridement may have sufficed to induce periapical healing. CBCT greatly helped the decision of avoiding further intervention that could have been difficult to negotiate. |
