Dens evaginatus is a developmental anomaly that can be defined as a tubercle from the surface of an affected tooth. It is composed of enamel and dentin usually enclosing pulp tissue. It is a rare dental anomaly commonly seen on premolars. A 12-year-old boy reported for the management of dental caries. He had bilateral occurrence of dens evaginatus on maxillary second premolars. The tubercle on the right side was unusually long without occlusal interference with the opposing primary mandibular second molar. Carious teeth were restored and the tubercle was left untreated. Management of dens evaginatus is determined by various factors which are discussed in decision-support system. Pulpal complication due to caries or fracture of tubercle can occur; hence it should be periodically monitored.
畸形中央尖是一种发育异常，可定义为患牙表面的一个结节。它通常由釉质和牙本质组成，内部包绕牙髓组织。这是一种罕见的牙齿异常，常见于前磨牙。一名12岁男孩前来治疗龋齿。他上颌第二前磨牙双侧出现畸形中央尖。右侧的结节异常长，与下颌对侧的乳第二磨牙无咬合干扰。龋坏牙进行了修复，结节未作处理。畸形中央尖的处理取决于多种因素，决策支持系统对此进行了讨论。由于龋齿或结节折断可能发生牙髓并发症，因此应定期监测。
