摘　　要：目的：观察MTA在前磨牙畸形中央尖预防性盖髓术中的疗效。方法选择2011年7月～2013年7月在我科就诊的未感染前磨牙高陡畸形中央尖患者66例牙齿78颗，随机分为两组，分别用MTA和氢氧化钙进行预防性盖髓，术后3、6、12个月及2年后复查，观察疗效，评价疗效。结果术后3个月复查，MTA组成功率为97%，Dycal组成功率为95%，比较两组近期疗效，差异无统计学意义（P＞0.05），术后2年复查， MTA组成功率为95%，Dycal组为72%，比较两组之间远期疗效，MTA组明显高于Dycal组，差异有统计学意义（P＜0.05）。结论应用MTA行前磨牙畸形中央尖预防性盖髓术是一种较好的治疗方法。Objective To observe the clinical effect of MTA applied to preventive pulp capping of prenmolar abnormal central cusp.Methods 78 unifected premolar steep abnormal central cusp teeth collected from 66 case were treated in our department of our hospital during June in 2011 to June in 2013.They were randomly divided into two groups .MTA was used in preventive pulp capping in the experimental group while Dycal was applied in the control group.At each （3、6、12months and two group）,the teeth were assessed dimically to evaluate clinical effect.Results After three months ,the treatment success rate of the MTA group was 97% and the treatment success rate of the Dycal group was 95%.There was no statistically significant difference at the shot term clinical effect between the two groups（P〉0.05）.After two years ,the treatment success rate of the MTA group was 95% and the treatment success rate of the Dycal group was 72% ,The long term clinical effect of the treatment with MTA was better than Dycal in preventive pulp capping（P〈0.05）.
