  • Title: A fused maxillary central incisor with dens evaginatus as a talon cusp.
    Author: Danesh G, Schrijnemakers T, Lippold C, Schäfer E.
    Journal: Angle Orthod; 2007 Jan; 77(1):176-80. PubMed ID: 17029553.
    Abstract:
    This report presents a rare case of concurrence of dens evaginatus and dental fusion affecting the maxillary right upper central incisor of a 9-year-old male patient. An association of dens evaginatus and dental fusion within the same tooth is rare. In this case, an orthopantomogram, a lateral cephalogram, intraoral radiographs, and a magnetic resonance tomogram were made to obtain a proper diagnosis and to confirm the exact path of the root canals. Because of a forced bite, an orthodontic treatment involving cusp reduction was initiated. During the cusp reduction, no traumatic intraoperative exposure of pulp tissue occurred, and no endodontic or surgical treatment procedures were necessary. After a multibracket treatment, a harmonious integration of the tooth in the upper dental arch was achieved.
