摘　　要：畸形中央尖(central cusp deformity)是一种牙齿形态异常的牙体硬组织非龋性疾病,一般位于牙合面中央窝处,呈圆锥状突起,多见于下颌前磨牙,尤以第二前磨牙最多见。本文报告了1例,除因正畸原因已拔除的2个前磨牙外,剩余的6个前磨牙均有畸形中央尖的病例,结合文献回顾,对其相关病因、临床表现、治疗进行总结,为临床诊治提供参考。Central cusp deformity is a disease characterized by deformed teeth with non- carious lesion of dental hard tissue,generally located in the central facial fossa with conical projections,and more commonly located in mandibular premolars,especially the second premolars. This paper reported a case whose two premolar teeth were removed due to orthodontic reasons,and the remaining six premolar teeth had central cusp deformity. Besides,relevant literature was reviewed to summarize the etiology,clinical manifestation and treatment of central cusp deformity so as to provide a reference for clinical diagnosis and treatment.
