摘　　要：掌握根管形态至关重要,利于患牙根管治疗的清理、成形及严密充填。但牙齿的发生发育受遗传因素的调控和后天因素的影响。牛牙症是一种少见的、以髓腔增大为主要特征的牙齿形态变异,因髓室底低,根分叉移向根尖段,根管数目变异,导致根管治疗难度极高,预后不确切,增加临床诊治难度,故牛牙症的诊断和治疗非常重要。本文就牛牙症的发生机制及发生率、诊断分型和鉴别诊断、治疗原则及预后,进行总结归纳,以期能帮助临床医生诊治此类疾病。Understanding the root-canal system is vital and benefits canal cleanliness, shape, and block when performing root canal treatment. However, tooth genesis and development are regulated by genes and affected by the environment. Taurodontism, a rare tooth anomaly, is featured with enlarged pulp chamber, apical displacement of the pulp floor, root bifurcation, and variations in root canal. Dealing with this disease through root canal treatment is challenging and prognosis is uncertain. Thus, taurodontism diagnosis and treatment are important. This article focuses on taurodontism pathogenesis, diagnosis, classification, differential diagnosis, treatment, and prognosis and summarizes some views for dentists.
