A review of the developmental dental anomaly, dans evaginatus, and a discussion of its clinical management is presented. Fracture or wear of the tubercle of dens evaginatus frequently results in pulp necrosis and early periapical infection, often prior to completion of root formation. Early recognition of this anomaly, followed by timely treatment can prevent the loss of pulp vitality in these teeth. Patients presenting with nonvital teeth and incomplete root development have been successfully treated by apexification followed by conventional endodontic therapy.
本文对发育性牙异常——畸形中央尖进行了综述，并讨论了其临床处理方法。畸形中央尖的结节折断或磨损常导致牙髓坏死和早期根尖周感染，且往往在牙根形成完成之前就会发生。早期识别这种异常并及时治疗，可以防止这些牙齿的牙髓活力丧失。对于牙根发育不全且牙髓无活力的患者，通过根尖诱导成形术继以常规根管治疗已成功治愈。
