氢氧化钙联合碘仿在根管封药中的疗效观察

Research of the Efficacy and Safety of Combined Calcium Hydroxide and Iodoform in Root Canals Therapy

目的比较应用氢氧化钙联合碘仿与甲醛甲酚在根管治疗中的疗效和安全性。方法将245例患者随机分为2组,治疗组129例患者(129颗牙)采用氢氧化钙联合碘仿在根管内封药,对照组116颗采用甲醛甲酚根管内封药。7 d复诊,观察2组的疗效及不良反应。结果根管内封药后7天复诊,治疗组有效率95.2%,对照组有效率85.8%,两组比较差异有统计学意义(χ2=6.31,P<0.05)。结论氢氧化钙联合碘仿根管消毒临床疗效优于甲醛甲酚,不良反应少,值得临床推广应用。

Objective To compare the efficacy and safety of combined calcium hydroxide and Iodoform vs formacresol in root canals therapy. Method 245 patients（245 teeth） were randomly divided into two groups. The treatment group 129 teeth were treated with calcium hydroxide and Iodoform. The contrast group 116 teeth were treatment with formaeresol, after 7-10 days, the clinical response to therapy and adverse effects were recorded. Results The therapeutic effect of calcium hydroxide combined with Iodoform was better（95.2%） than that of formocresol（85.8%）in a week. There was distinct difference between two groups（x^2=6.31, P〈0.05）. Conclusion Root canal disinfection drugs with combined Calcium hydroxide and Iodoform showed good efficacy and safety, with little adverse reactions.
