The Clinical Effect of Septomixine on Chronic Periapical Periodontitis

目的观察根尖脓肿软膏Septomixine根管消毒治疗窦道型慢性根尖周炎的临床疗效。方法将139例窦道型慢性根尖周炎患者共139颗患牙随机分为3组,均采用Protapt手用镍钛锉逐步深入法根管预备,并行窦道通过术。预备完成后Ⅰ组将Septomixine导入根管消毒,Ⅱ组将氢氧化钙糊剂导入根管消毒,Ⅲ组预备后甲醛甲酚棉捻根管消毒。1周后复诊记录约诊间痛的发生情况以及窦道愈合情况。结果 Septomixine组术后疼痛反应及窦道愈和时间明显少于甲醛甲酚组,两组差异有显著性。而Septomixine组与氢氧化钙组窦道愈和时间无显著差异,但其在术后疼痛控制方面优于氢氧化钙组。结论 Septomixine是一种有效治疗窦道型慢性根尖周炎的根管消毒药物。

Objective To evaluate the clinical effect of Septomixine as root canal disinfectant on chronic periapical periodontitis.Methods 139 patients with chronic periapical periodontitis（including 139 sick roots） were randomly classified into three groups,and root canals were prepared and pressurized washing using the hand ProTaper NiTi instruments with crown-down techinque.The patients in group I were administered with Septomixine,and the patients in groupⅡwere administered with calcium hydroxide and those in group Ⅲ were administered with formaldehyde and cresol（FC）.After one week,the response of patients were evaluated.Results Compared with Group III,GroupⅠhad less postoperative pain,with shorter time of sinus closed.There were no obvious differences between groupⅠand groupⅡ in the time of sinus closed.Conclusions Septomixine can be used as a root canal disinfectant in treating refractory and chronic periapical periodontitis.
