This is a report of two patients with isolated facial talon cusps. One occurred on a permanent mandibular central incisor; the other on a permanent maxillary canine. The locations of these talon cusps suggests that the definition of a talon cusp include teeth in addition to the incisor group and be extended to include the facial aspect of teeth.
本文报告了两例孤立性面部尖牙症患者。一例发生在恒牙下颌中切牙;另一例发生在恒牙上颌尖牙。这些尖牙症的位置表明,尖牙症的定义除了包括切牙组外,还应包括其他牙齿,并应扩展到包括牙齿的面部。
