The talon cusp is a relatively uncommon dental anomaly manifested as an accessory cusp-like structure on the crown of anterior teeth. The presence of a talon cusp can cause clinical problems. This article reports the case of a patient presenting a talon cusp affecting the permanent maxillary right central incisor causing clinical problems related to caries, displacement of the tooth, occlusal position and tendency to dental traumatism. The management of this tooth included caries removal and reduction of the cusp. Pulp-capping with calcium hydroxide was required because of the presence of pulp horn extensions in the talon cusp.
畸形中央尖是一种相对罕见的牙齿异常，表现为前牙牙冠上类似副尖的结构。畸形中央尖的存在可能会引发临床问题。本文报告了一例患者，其右上颌恒中切牙出现畸形中央尖，导致了与龋齿、牙齿移位、咬合位置及牙齿外伤倾向相关的临床问题。该牙齿的治疗包括去除龋齿和磨除牙尖。由于畸形中央尖内存在髓角延伸，因此需要用氢氧化钙进行盖髓治疗。
