title: Endodontic management of mandibular central incisor fused to a supernumerary tooth associated with a talon cusp: a case report.
abstract: OBJECTIVE
  To report the successful non-surgical endodontic management of a mandibular central incisor fused to a supernumerary tooth associated with a talon cusp.
  
  
  CONCLUSIONS
  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.
  
  
  CONCLUSIONS
  •  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.
