摘　　要：目的分析牙本质折断恒牙的牙髓预后及其影响因素。方法对行间接盖髓治疗且复诊时间大于2年的牙本质折断病例进行回顾分析,记录牙髓预后情况,回归分析影响牙髓预后的危险因素。结果收集到牙本质折断病例205例,涉及患牙242颗。242颗患牙中,78颗(32.2%)发生了牙髓坏死,3颗(1.2%)发生了牙髓钙化。牙本质折断后行间接盖髓术的成功率为67.8%。复诊期间177颗年轻恒牙中141颗根尖孔闭合。冠折近髓程度与牙髓坏死率有相关性(P=0.001)。结论牙本质折断恒牙行间接盖髓术的预后较好,冠折近髓程度是判断牙髓预后的重要指征。Objective To investigate the pulp prognosis and influence factors of dentin-fractured teeth. Methods Case records of dentin-fractured teeth treated with indirect pulp capping and with more than 2 years follow-up were collected. The data related to trauma information and pulp prognosis were recorded and the influence factors were ana- lyzed by Logistic regression. Results This study consisted of 205 cases with 242 dentin-fractured teeth. Among 242 teeth, pulp necrosis occurred in 78 teeth（32.2%） and pulp calcification occurred in 3 teeth（1.2%）. The success rate of indirect pulp-capping on dentin-fractured teeth was 67.8%. During observation period, 141 out of 177 young per- manent teeth completed root development. The extent of fracture close to pulp was an indicator for pulp prognosis （P=0.001）. Conclusion The prognosis of indirect pulp-capping on dentin-fractured permanent teeth is good. The extent of fracture close to pulp should be considered to evaluate the prognosis of the pulp.
