摘　　要：目的评价氢氧化钙和碘仿氢氧化钙糊剂作为根管消毒药物对慢性根尖周炎的封药效果.方法选取60例我院就诊的慢性根尖周炎的患者,随机分2组,每组30人,均在初次就诊时行常规开髓及根管预备处理,A组根管内导入氢氧化钙糊剂,B组根管内导入碘仿氢氧化钙糊剂,封药1周后复诊,记录复诊时临床检查.结果患牙封药1周后效果对比,B组的封药显效率(66.67%)大于A组(50%),且B组总有效率为96.67%,高于A组的86.67%,两组封药效果间差异有统计学意义(P<0.05).结论碘仿氢氧化钙在慢性根尖周炎治疗过程中作为根管消毒药物效果较单纯氢氧化钙糊剂效果更好,值得临床推广.Objective To evaluate the sealing effect of calcium hydroxide and iodoform calcium hydroxide paste as root canal disinfectants on chronic periapical periodontitis.Methods 60 patients with chronic periapical periodontitis in our hospital were randomly divided into two groups,30 in each group.All patients were treated with conventional pulpotomy and root canal preparation at the first visit.Calcium hydroxide paste was introduced into the root canal of group A,and iodoform calcium hydroxide paste was introduced into the root canal of group B.The clinical examination was recorded after one week of sealing.Results One week later,the effective rate of group B(66.67%)was higher than that of group A(50%),and the total effective rate of group B was 96.67%,higher than that of group A(86.67%).The difference between the two groups was statistically significant(P<0.05).Conclusion Iodoform calcium hydroxide in the treatment of chronic periapical periodontitis as root canal disinfectant effect is better thancalcium hydroxide paste,worthy of clinical promotion.
