目的 :观察碘附溶液瘘道通过一次法治疗有瘘型慢性尖周炎的临床疗效。方法 :随机将病人分为碘附溶液瘘道通过组 (治疗组 )和常规根管治疗组 (对照组 )进行治疗 ,于术后 4周内每周一次观察瘘道愈合情况及有无急性炎症改变 ,1年后复查评定疗效。结果 :术后 1周～ 4周治疗组瘘道愈合情况明显优于对照组 ,差异非常显著 (P<0 .0 1) ,而 1年疗效两组无明显差异 (P>0 .0 5 )。结论 :碘附溶液瘘道通过一次法治疗有瘘型慢性尖周炎 ,可使瘘道迅速愈合 ,缩短疗程 ,提高近期疗效。认为治疗后早期瘘道愈合情况可作为治疗有效与否的佐证。
Objective: To observe the clinical efficacy of iodine solution fistula through one-time treatment of fistula chronic periapical. Methods: The patients were randomly divided into iodine solution fistula passage group (treatment group) and conventional root canal treatment group (control group) for treatment. The fistula healing and acute inflammation were observed once a week Change, review after 1 year to assess efficacy. Results: The healing of the fistula in the treatment group after 1 week to 4 weeks was significantly better than that in the control group (P <0.01), but no significant difference was found between the two groups in one year (P> 0.05) . Conclusion: Iodine solution fistula through a fistula treatment of chronic periapical fistula, rapid healing of the fistula can shorten the course of treatment and improve the short-term efficacy. That the treatment of early fistula healing can be used as evidence of effective treatment or not.
