摘　　要：目的:探讨混合牙列期恒前牙根折的临床疗效。方法:选取2019年12月~2022年12月在我院儿童牙病科就诊的混合牙列期恒前牙根折病例32例(共41颗患牙),按根折部位、牙根发育情况及就诊时间进行分组,对根折愈合率及牙髓存活情况进行分析。结果:41颗患牙中,34颗愈合(82.9%),硬组织愈合19颗(46.3%),牙髓存活31颗(75.6%)。根折预后与根折部位及牙根发育情况有关(P<0.05)。结论:根折部位越靠近根颈处预后越差,年轻恒牙根折预后优于成熟恒牙。Objective:To investigate the clinical efficacy of permanent anterior root fractures in mixed dentition.Methods:A total of 32 cases(41 teeth)with root fractures of permanent anterior teeth in mixed dentition were selected and treated in the Department of Pediatric Dentistry of our hospital from Dec 2019 to Dec 2022.Patients were divided into groups according to the location of root fracture,the development of root and the visiting time.The healing rate of root fracture and pulp survival were analyzed.Results:Among the 41 teeth,34 teeth(82.9%)were healed,19 teeth(46.3%)were hard tissue healed,and 31 teeth(75.6%)were pulp survived.The prognosis of root fractures were related to the location of root fracture and the development of root(P<0.05).Conclusion:The closer the root fracture site is to the cervical root,the worse the prognosis.The immature permanent teeth with root fracture has better prognosis than the mature permanent teeth.
