Sachdeva GS, Malhotra D, Sachdeva LT, Sharma N, Negi A. Endodontic management of mandibular central incisor fused to a supernumerary tooth associated with a talon cusp: a case report. International Endodontic Journal, 45, 590-596, 2012. Abstract Aim To report the successful non-surgical endodontic management of a mandibular central incisor fused to a supernumerary tooth associated with a talon cusp. Summary Fusion and gemination are developmental anomalies of teeth that may require endodontic treatment. In this article, a case of successful endodontic management of a permanent mandibular right central incisor fused to its supernumerary counterpart associated with a talon cusp is reported. The incidence of fusion in mandibular anteriors is rare. A search of the literature failed to reveal any reports on the fusion of a permanent mandibular central incisor with its supernumerary counterpart associated with a talon cusp. Successful non-surgical endodontic management of a case is reported. Key learning points Fused and geminated teeth requiring endodontic treatment present diagnostic and technical challenges., An exact differentiation between fusion and gemination may not be critically important for treatment., The use of an operating microscope for detection of additional root canal orifices in complicated cases is recommended.
