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。
Objective: To compare the clinical efficacy of calcium hydroxide paste and calcium hydroxide iodoform paste for root canal disinfection. Methods: A total of 281 patients with chronic pulpitis and chronic periapical periodontitis were selected. After conventional root canal preparation, they were randomly divided into two groups: 143 cases in group A, calcium hydroxide iodoform paste was enclosed in root canal; B Group 138 cases, sealed calcium hydroxide paste. After 48 hours, the patients were interviewed by phone to compare the incidence of pain (EIP) during root canal treatment. One week follow-up was performed to compare the clinical efficacy of the two groups. Results: The incidence of EIP in group A and group B was significantly different within 48 h (P <0.05). There was no significant difference in efficacy after one week (P> 0.05). CONCLUSION: Calcium hydroxide paste and calcium hydroxide iodoform paste are the ideal root canal disinfectants, but the calcium hydroxide iodoform paste can reduce the EIP more significantly.
