Treat the therapy-resistant apical periodontitis by sealing mycostain in root canals.

目的 :探讨治疗难治性根尖周炎的有效手段 ,评价制霉菌素根管内用药治疗难治性根尖周炎的临床疗效。方法 :76例根尖周病久治不愈的患者 ,采用制霉菌素根管内用药 ,观察封药后的反应。结果 :显效 5 3例 ,有效 17例 ,无效 6例。结论 :如常规用药治疗多次 ,疼痛仍不缓解的根尖周炎病例 ,根管内封入制霉菌素后可取得较好的疗效。

Objectives:To investigate an effective treatment for the rapy-resistant apical periodontitis and evaluate clinical effect of mycostatin,as root canal medicament,in treating therapy-resistant apical periodontitis.Methods:Mycostatin was sealed in root canals in 76 cases with therapy-resistant apical periodontitis,and post-operation response was evaluated.Results:The mycostatin was significantly effective in 53 cases, effective in 17 cases and invalid in 6 cases.Conclusions:In some apical periodontitis, the pain wouldn't be relieved after conventional medication treatment, but better clinical results can be obtained after sealing mycostatin in root canals.
