目的比较根管治疗中应用不同氢氧化钙(CH)制剂的疗效。方法选择慢性根尖炎患者153例作为研究对象,随机分为两组,CH+替硝唑组和CH+碘仿组,对比两组治疗暂封1周后的疼痛发生情况与疗效。结果 CH+替硝唑组、CH+碘仿组的疼痛发生率分别为12%、7%,CH+碘仿组优于前者;从疼痛程度分级情况看,CH+碘仿组的分级程度情况最好,0级所占比率最高(65%),1级+2级所占比率最低(8%);从疗效对比看,CH+碘仿组疗效为优者所占比率达91.3%,明显高于CH+替硝唑组的72.5%。结论 CH+碘仿组的制剂在疗效上优于CH+替硝唑组。
Objective To compare the efficacy of different calcium hydroxide (CH) preparations in root canal therapy. Methods A total of 153 patients with chronic apical inflammation were enrolled in this study. Patients were randomly divided into two groups: CH + tinidazole group and CH + iodoform group. The incidence and effect of pain after 1 week of treatment were compared. Results The incidences of pain in CH + tinidazole group and CH + iodoform group were 12% and 7%, respectively, and CH + iodoform group was superior to the former. According to the grading of pain degree, the grading degree of CH + iodoform group was the best, 0 (65%), the lowest level (level 1 + 2) (8%). In terms of curative effect, the rate of CH + iodoform group was 91.3%, which was significantly higher than that of CH + 72.5% of the azole group. Conclusion The preparation of CH + iodoform group is superior to CH + tinidazole group in efficacy.
