目的对比2种氢氧化钙制剂在根管消毒中的疗效。方法临床选择急慢性根尖周炎患者的261颗牙随机分为2组,在根管治疗过程中分别采用氢氧化钙碘甘油糊剂和Vitapex 2种根管消毒药进行根管消毒。比较封药7 d和根管治疗完成后1年2组的临床效果并进行统计分析。结果氢氧化钙碘甘油糊剂和Vitapex临床效果差异无统计学意义(P>0.05)。结论氢氧化钙碘甘油糊剂是理想经济的根管消毒药。
Objective To compare the efficacy of two calcium hydroxide preparations in root canal disinfection. Methods A total of 261 teeth of acute and chronic periapical periodontitis patients were randomly divided into two groups. The root canal was disinfected with two kinds of root canal sterilizers (calcium hydroxide iodine glycerol paste and Vitapex respectively). The clinical effects of the sealant for 7 days and 1 year after root canal treatment were compared and analyzed statistically. Results There was no significant difference in clinical efficacy between calcium hydroxide iodized glycerol paste and Vitapex (P> 0.05). Conclusion Calcium hydroxide Iodogalactan paste is an ideal and economical root canal disinfectant.
