目的比较碘仿根管糊剂、甲硝唑钙维它根管糊剂、奥硝唑根管糊剂对慢性根尖周炎的治疗效果,为治疗经久不愈的慢性根尖周炎提供临床依据。方法选择瘘管型慢性根尖周炎病例350例共360个牙随机分成对照组A、对照组B和实验组,每组各120个牙,分别用碘仿根管糊剂、甲硝唑钙维它根管糊剂、奥硝唑根管糊剂进行充填,然后根据治疗效果进行对比分析。结果治疗6个月后,实验组有效率96.67%,对照组A为68.33%,对照组B为85.00%,实验组与对照组疗效差异有统计学意义(P<0.05)。结论奥硝唑根管糊剂治疗慢性根尖周炎疗效优于碘仿根管糊剂和钙维它根管糊剂。
Objective To compare the therapeutic effects of iodoform-based root canal paste, metronidazole calcium-vitamin root canal paste and ornidazole root canal paste on chronic apical periodontitis, and to provide clinical experience in the treatment of chronic periapical periodontitis in accordance with. Methods A total of 360 teeth of 350 patients with chronic periapical fistulae were randomly divided into control group A, control group B and experimental group, with 120 teeth in each group. Metronidazole root canal paste, metronidazole calcium dimension It is root canal paste, ornidazole root canal paste filling, and then according to the treatment effect of comparative analysis. Results Six months after treatment, the effective rate of the experimental group was 96.67%, that of the control group A was 68.33%, and that of the control group B was 85.00%. There was significant difference between the experimental group and the control group (P <0.05). Conclusion Ornidazole root canal paste in the treatment of chronic apical periodontitis is superior to iodoform root canal paste and calcium-vitamin root canal paste.
