MTA在前磨牙畸形中央尖预防性盖髓术中的疗效观察 赵献平 李慧良 徐芳 郑州市第一人民医院口腔科 郑州 450004 [摘要] 目的：观察MTA在前磨牙畸形中央尖预防性盖髓术中的临床疗效 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例共计78颗牙齿，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，观察治疗效果，评价临床疗效。结果： 术后3个月复查，MTA组成功率为97%，Dycal组成功率为95%，比较两组之间近期临床疗效无统计学差异(P0.05)，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，两组之间有显著性差异(p0.05)。 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。 [关键词] 畸形中央尖 ； MTA； Dycal； 预防性盖髓术 ［中图分类号］R 781.2 Clinical observation of MTA applied to the preventive pulp capping of premolar abnormal central cusp Zhao Xianping ；Li Huiliang ;Xu fang Department of Stomatology,Zhenzhou First People, s Hospital,,Zhengzhou ,450004 [Abstract] Objective:To observe the clinical effect of MTA applied to preventive pulp capping of prenmolar abnormal central cusp. Method : 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. Result: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(P0.05).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(P0.05). Conclusion: MTA applied to the preventive pulp capping of central cusp deformity is a better way. [Key word] abnormal central cusp ; MTA ; Dycal ; Preventive pulp capping Correspo
