摘　　要：目的:观察应用Er:YAG激光辅助直接盖髓术和断冠再接术治疗复杂冠折恒前牙的疗效,为外伤牙复杂冠折的激光微创治疗提供临床参考。方法:选择25例恒前牙外伤复杂冠折患者的32个患牙,采用Er:YAG激光辅助直接盖髓术和断冠再接术,术后1、3、6、12个月复查,依据临床检查、影像学检查、满意度评分等标准进行临床疗效观察与评价。结果:持续疗效观察12个月,患牙发生牙齿敏感的占比仅为10%,再接断冠完整性、稳固性、边缘密合性成功率达90%,影像学检查亦仅有10%的患牙出现根尖发育异常或根尖周病变,患者对患牙治疗后的美观程度、舒适程度、咀嚼功能和固位效果的满意度调查评分均较高。结论:Er:YAG激光辅助直接盖髓术和断冠再接术治疗恒前牙复杂冠折具有较好疗效,可以做为微创治疗复杂冠折的一种临床选择。AIM:To observe the efficacy of Er:YAG laser-assisted direct pulp capping and crown fragment reattachment in the treatment of complicated crown fracture in anterior permanent teeth,and provide a clinical reference for the minimally invasive laser treatment of complicated crown fracture in traumatized teeth.METHODS:Thirty two traumatized anterior permanent teeth with complicated crown fracture from twenty five patients were selected in the present study,then treated by Er:YAG laser-assisted direct pulp capping and crown fragment reattachment,and reviewed at 1,3,6 and 12 months after the treatment.The clinical efficacy was observed and evaluated based on the criteria of clinical examination,imaging examination and satisfaction scores.RESULTS:After 12 months,only 10%of the teeth showed sensitive.The success rates of the integrity,stability and marginal closeness of the reattached fragments were 90%.Additionally,abnormal apical development or periapical lesions were observed in only 10%of the treated teeth.Moreover,the patients showed well satisfaction with the aesthetics,comfort,mastication and retention of the treated teeth.CONCLUSION:Er:YAG laser is effective in assisting direct pulp capping and crown fragment reattachment in the treatment of anterior permanent teeth with complicated crown fracture.The method used in this study could be utilized as within a clinical minimally invasive treatment option for the complicated crown fracture.
