The reverse claw: Report of an extremely rare facial talon cusp
A 25-year-old female reported to the dental clinic with complaint of decayed tooth in the left back region of the lower jaw. On examination an elevation on the labial aspect of crown of the maxillary right permanent central incisor was noticed. The elevation was broader at the cervical area and gradually tapered toward the incisal edge to give a ridge-like appearance. The cervical area had light brown discoloration []. No abnormalities were noticed on the palatal surface of the tooth. A midline diastema existed between the two central incisors. The periapical area appeared to be normal. Normal responses were obtained on the pulp testing procedure. Intraoral periapical radiograph of the area revealed V-shaped radiopacity in relation to the coronal aspect of maxillary right central incisor, extending 1 mm below the incisal edge to the cementoenamel junction. The radiopacity of the V-shaped area was comparable to that of enamel. No pulpal or canal changes were observed. No changes in the periapical area were noticed []. Based on these clinical and radiological features diagnosis of facial talon cusp was made. A thorough oral prophylaxis was performed and the decayed molar was restored. As the patient had no complaints with the abnormal tooth (with facial talon) she was kept on a yearly periodic recall.
