摘　　要：畸形中央尖(central cusp deformity)是一种牙齿形态发育异常,畸形中央尖折断所引起根尖周囊肿(炎症性牙源性囊肿)较为常见并可以预测其病变的发生与发展,但合并发育性牙源性囊肿鲜有报道。发育性牙源性囊肿(developmental odontogenic cyst)是由牙齿发育和/或萌出过程中的某些异常所导致的病理性上皮衬里空洞,目前对于发育性牙源性囊肿的组织来源和发病机制认识尚不深入,许多理论建立在推测的基础之上。本文报道1例双侧下颌第二前磨牙畸形中央尖,一侧伴发根尖周囊肿,另一侧伴发发育性牙源性囊肿。Central cusp deformity is a type of non-carious dental hard tissue disease characterized by abnormal tooth morphology.Periapical cysts,resulting from central cusp deformity fractures,are commonly observed and can serve as indicators for the occurrence and progression of its lesions.Developmental odontogenic cysts are pathological cavities in the epithelial lining caused by abnormalities in tooth development and/or eruption.The tissue origin and pathogenesis of developmental odontogenic cysts remain poorly understood,with many theories still based on speculation.The present study presents a case of bilateral mandibular deformity with central apex,accompanied by radicular cysts on one side and developmental odontogenic cysts on the other side.
