目的:探讨年轻恒前牙外伤性冠折的治疗方法及疗效。方法:对120例160颗年轻恒前牙不同程度冠折病例分别采用直接光固化树脂修复、间接盖髓、活髓切断和根尖诱导成形术进行治疗,并经2年随访,观察根尖发育情况。结果:选用正确的方法治疗后,牙根继续发育形成,根尖孔封闭。直接固化树脂修复成功率达100%,间接盖髓成功率为75%,活髓切断成功率91%,根尖诱导成形术成功率93%。结论:年轻恒牙外伤性冠折应根据冠折程度选择最佳的治疗方法,以保证治疗的成功。
Objective: To investigate the treatment and efficacy of traumatic crown injury in young permanent anterior teeth. Methods: 120 cases of young permanent anterior teeth with varying degrees of crown fracture cases were treated with direct light curing resin, indirect pulp capping, pulpotomy and apexoplasty for treatment, and after 2 years of follow-up observation of apical development Happening. Results: After the correct method was selected, the root formation continued to develop and the apical foramen was closed. Direct cure resin repair success rate of 100%, indirect pulp capping success rate of 75%, pulp success rate of 91%, apical induction angioplasty success rate of 93%. Conclusion: Young permanent teeth traumatic crown should be based on the degree of coronary artery disease to choose the best treatment to ensure the success of treatment.
