氢氧化钙碘仿糊剂对年轻恒牙根尖诱导成形术的疗效观察

Observations on effects of calcium hydroxide and indoform paste on apexification of the young permanent teeth.

目的探讨氢氧化钙碘仿糊剂对年轻恒牙根尖诱导成形术(apexification,AP)的临床疗效。方法收集2003～2008年间在我科就诊的儿童牙外伤病例,共87颗受伤的年轻恒牙,随机分为两组,实验组45例,对照组42例,分别用氢氧化钙碘仿糊剂,氢氧化钙糊剂(calcium hydroxide paste,CH)行AP治疗。术后每3个月复诊1次,随访2年。结果实验组有效率91.12%,对照组有效率71.43%,两组间差异有统计学意义(P<0.05)。结论氢氧化钙碘仿糊剂对年轻恒牙的根尖诱导作用较单用CH更为有效。

Objective To probe into the clinical effects of calcium hydroxide and indoform paste on apexification of the young permanent teeth.Methods Cases of children dental trauma treated in our department from 2003 to 2008 were collected,and there were 87 young permanent teeth in all.These cases were divided into two groups randomly,there were 45 cases in the test group,which were treated with calcium hydroxide and indoform paste,42 cases in the control group,which were treated with CH.All cases were followed every 3 months for two years.Results The effective rate was 91.12% in the test group;in the control group it was 71.43%.The difference of effects was significant statistically（P0.05）.Conclusion The effects of calcium hydroxide and indoform paste on AP of the young permanent teeth is better than the control group only with CH.
