目的：探讨无髓牙(即经过根管治疗的牙)根纵裂的临床特点和诊断依据。方法14例患牙经影像学检查、翻瓣或拔除等方法确诊的根纵裂无髓牙，回顾性分析其病史、临床体征及影像学检查结果。结果14例确诊患牙中，磨牙6颗，前磨牙4颗，前牙4颗。14例患牙均有牙冠修复(其中10例有桩核)。14例牙周探诊均可及局限性的深牙周袋(≥7 mm)，根尖片表现以牙槽骨垂直吸收为主。5例患者有锥形束 CT 检查，其中1例通过 CT 直接诊断为根纵裂。结论无髓牙根纵裂的诊断可根据病史、临床特点、影像学检查等综合判断。

Objective To discuss the characteristics and diagnosis of vertical root fracture(VRF) in endodontically treated teeth. Methods Fourteen patients were diagnosed definitely by radiological examinations, flap elevations and being extracted, and retrospectively analysed the history, signs and the results of X-ray or cone beam computed tomography(CBCT) examinations. Results There were 6 molars, 4 premolars and 4 front teeth, respectively. All the 14 teeth had crown and 10 of them had posts. Conclusion The diagnosis of vertical root fracture in endodontically treated teeth is difficult. We should make diagnosis synthetically according to the history and clinical traits of patients.
