摘　　要：目的比较应用三氧化矿物凝聚体和甲醛甲酚进行乳牙深龋活髓切断术的疗效。方法选取乳磨牙深龋110颗行活髓切断术,将其随机分为MTA组54颗,FC组56颗。术后6、12、18个月复查,观察预后效果。结果术后6、12个月,MTA组和FC组总有效率比较,差异无统计学意义(P>0.05)。术后18个月,MTA组和FC组总有效率比较,差异有统计学意义(P<0.05)。结论 MTA可用于乳牙深龋活髓切断术,其远期疗效优于FC。Objective To contrast mineral trioxide aggregate（MTA） with formocresol （FC） clinical efficacy as a pulpotomy agent in deciduous teeth of deep caries.MethodsOne hundred and ten primary teeth were selected which were randomly assigned to experimental group （MTA pulpotomy were performed） and control group （FC pulpotomy were performed）.Patients were followed up for clinical and radiographic examination after 6,12,18 months.Results At 6 months and 12 months,the success rate between MTA and FC is not obvious different, there were no statistically signifi cant.At 18 months, the success rate between MTA and FC is different, there were statistically signifi cant difference.ConclusionMTA is an effective pulpotomy materials.
