替硝唑地塞米松碘仿糊剂控制根管治疗期间急症的效果评价

目的:用替硝唑地塞米松碘仿糊剂和甲醛甲酚液作为慢性根尖周炎的根管消毒剂,比较两者根管治疗期间急症发生的差异。方法:选择慢性根尖周炎恒牙520颗,随机分为2组,替硝唑地塞米松碘仿糊剂组(A组)和甲醛甲酚组(B组)。记录临床症状和体征,拍摄X线片,常规进行根管预备后,A组用替硝唑地塞米松碘仿糊剂消毒根管,B组用甲醛甲酚纸尖消毒根管,1周后复诊根充。记录临床症状和体征,并用临床根尖周指数(CPI)进行疗效评定,随访2a,观察疗效。结果:A组根管治疗期间急症的发生率明显低于B组(P<0.01),两组有显著性差异。2a后成功率比较,两组无显著性差异(P>0.05)。结论:替硝唑地塞米松碘仿糊剂作为根管消毒剂,可减少慢性根尖周炎根管治疗过程中急症的发生,远期效果可靠。

Effect of tinidazole-dexamethasome-iodoform paste on controlling endodontic interappointment emergencies

PURPOSE: To compare the clinical effect of tinidazole-dexamethasome-iodoform paste on intracanal dressing medication for teeth with chronic periapical periodontitis with that of formocresol. METHODS: 520 permanent teeth with chronic periapical periodontitis were selected and divided randomly into tinidazole-dexamethasome-iodoform paste group (A group) and formocresol group (B group). The periapical signs and symptoms were recorded, radiographs were taken. After root canal preparation, the tinidazole-dexamethasome-iodoform paste was used as an intracanal dressing medication for one week in A group and the formocresol paper point was used in B group. During the course of canal treatment, the clinical findings were assessed with clinical periapical index (CPI), the cases were followed up for two years. RESULTS: There was significant difference between A and B group (P<0.01), group A was better than group B. There was no significant difference between two groups of the success rate after following up two years (P>0.05). CONCLUSION: As an intra-canal sterilization medication,tinidazole-dexamethasome-iodoform can reduce the occurence of endodontic interappointment emergencis in teeth with chronic periapical periodontitis and has a good long-term result.
