氢氧化钙糊剂和氢氧化钙碘仿糊剂用于根管消毒的疗效比较

目的:比较氢氧化钙糊剂和氢氧化钙碘仿糊剂用于根管消毒的临床疗效。方法:选择慢性牙髓炎和慢性根尖周炎患者共281例,常规根管预备成形后,随机分为2组:A组143例,在根管内封入氢氧化钙碘仿糊剂;B组138例,封入氢氧化钙糊剂。封药后48 h电话回访,比较根管治疗期间疼痛(EIP)发生率;一周复诊,比较2组临床疗效。结果:A组和B组48 h内EIP发生率差异有显著性(P<0.05),一周后疗效差异无显著性(P>0.05)。结论:氢氧化钙糊剂和氢氧化钙碘仿糊剂都是较理想的根管消毒剂,但氢氧化钙碘仿糊剂减轻EIP疗效更显著。

The curative effect of calcium hydroxide paste and calcium hydroxide iodoform paste in root canal disinfection

OBJECTIVE To compare the curative effect of calcium hydroxide paste and calcium hydroxide iodoform paste in root canal disinfection.METHODS 281 patients suffering from chronic pulpitis and chronic periapical periodontitis were selected.The root canals were prepared and the calcium hydroxide paste(Group A) or the calcium hydroxide paste(Group B) were randomly sealed into the root canal.Group A included 143 sufferers and Group B included 138 sufferers.Called them in 48 hours after operation to know if they had got endodontic inter-appointment pain(EIP).Compared the curative effect of the two groupes when they returned in a week.RESULTS There was statistically significant difference at EIP between the two groups(P<0.05),but no statistically difference at the curative effect between the two groups in a week(P>0.05).CONCLUSION Both calcium hydroxide paste and calcium hydroxide iodoform paste are both efficacious for root canal disinfection.But calcium hydroxide iodoform paste is more efficacious than calcium hydroxide paste in reducing the EIP.
