摘　　要：目的比较无机三氧化聚合物(MTA)、玻璃离子水门汀(GIC)和银汞合金3种修复材料治疗医源性髓腔穿孔的临床效果。方法所有临床病例随机分组,共有62例髓腔穿孔病例纳入分析,其中MTA组21例,GIC组22例,银汞合金组19例。分别进行穿孔修补并进行彻底的根管治疗和充填,术后3个月,根据临床症状评价短期疗效。结果 MTA组有效率为90.48%(19/21),GIC组有效率为59.09%(13/22),银汞合金组有效率为52.63%(10/19)。MTA组与其他2组存在统计学差异,MTA组有效率高于GIC组和银汞合金组(P<0.05)。结论 MTA具有良好生物相容性,能够促进硬组织的形成,封闭性能好,在髓腔穿孔修补中的临床效果优于GIC和银汞合金。Objective The purpose of this study was to investigate the clinical effects of GIC、amalgam and MTA in pulp chamber perforation repair.Methods Cases were divided into three groups randomly.In total,sixty-two cases were involved in our experiment, with MTA group 21 cases,GIC group 22 and amalgam group 19.All of the cases received the pulp chamber perforation repair with one of the three materials and perfect root canal therapy,and after a 3 months＇ follow-up,the clinical effects were evaluated.Results The type of the materials used had significant effects on canal perforation repair.MTA was more effective than GIC and Amalgam statistically （P0.05）.Conclusions MTA is a more suitable material than GIC and amalgam in pulp chamber perforation repair.
