摘要
目的观察甲硝唑氢氧化钙碘仿糊剂应用于难治性慢性根尖周炎根管内封药消毒的临床效果。方法选择经过根管预备清理后封药消毒3次以上症状未消失的80例难治性慢性根尖周炎病例,随机分为实验组与对照组,实验组(40例)在根管内封入甲硝唑氢氧化钙碘仿糊剂进行消毒,对照组(40例)在根管内继续封入FC棉捻消毒,对两组根管封药消毒效果进行临床观察和比较。结果实验组封药有效率为92.5%(37/40),对照组封药有效率为47.5%(19/40),两组的封药后的有效率存在极显著差异(χ2=19.28,P<0.01)。结论对于甲醛甲酚根管内反复换药疗效不佳的难治性慢性根尖周炎病例,在根管内封入甲硝唑氢氧化钙碘仿糊剂进行消毒疗效显著。因此甲硝唑氢氧化钙碘仿糊剂可作为难治性慢性根尖周炎的有效治疗方法。
Objective To observe the clinical effect of flagyl calcium hydroxide iodoform paste used in root canal disinfection on chronic refractory periapical periodontitis.Methods Choosing 80 teeth of chronic refractory periapical periodontitis,they were implemented more than 3 times conventional root canal preparations.These 80 teeth were divided at random into a test group（n=40） and a control group（n=40）.The test group was disinfected using flagyl calcium hydroxide iodoform paste in root canals,while the formocresol cotton was used for the control group,and clinical observation and contrast on root canal disinfection were continued between these 2 groups.Results The effective rate in test group was 92.5%（37/40）,while that in control group was 47.5%（19/40）,extremely significant difference（χ2=19.28,P0.01）existed between these 2 groups.Conclusion Flagyl calcium hydroxide iodoform paste used in root canal disinfection on chronic refractory periapical periodontitis is worth applying in clinical practice.
