畸形中央尖是一种临床常见的牙齿发育异常,表现为牙齿形态异常、牙齿面突起的结节。受咬合创伤可引起畸形中央尖折断或磨损,使得髓角或牙本质暴露,引起牙髓感染、坏死,严重者可导致根尖周炎。由于年轻恒牙萌出早期即可出现畸形中央尖折断,牙根生长发育常受到影响,严重影响口腔健康。因此,对畸形中央尖患牙采取积极措施,预防畸形中央尖折断或早期干预去除畸形中央尖极其重要。本文就国内外学者对畸形中央尖折断的防治理念及相关治疗药物作一综述。

Dens evaginatus is a common morphological deformity in permanent teeth which is characterized by the presence of an abnormal central cusp on the occlusal surface. The abnormal central cusp would always be abraded or fractured due to occlusal interferences and afterwards lead to an exposed pulp or dentin. Pulpitis, pulp necrosis or even periapical infectious diseases would eventually occur. Usually, the fracture of abnormal central cusp happens in the early stage of tooth eruption and consequently affects the development of root together with the adverse effects on the oral health. As a result, it is of critical importance to prevent dens evaginatus′s fracture with necessary treatments in the early time. This review focuses on the concepts of prevention and treatment of dens evaginatus′s fracture as well as related therapeutic materials.
