目的：探讨根管治疗术在根尖周病治疗中的应用及其远期疗效。方法：将本院收治的128例根尖周病患者随机分为观察组与对照组，每组64例，其中观察组采取一次性根管治疗术，对照组采取常规多次性根管治疗术，比较两组患者治疗后的临床疗效及远期疗效。结果：观察组治疗总有效率为91.55%，对照组为89.04%，两组比较差异无统计学意义（P>0.05）；观察组根充后6个月总有效率为90.14%，1年为87.32%，2年为84.51%，对照组分别为87.67%、86.30%、83.56%，两组同期比较差异无统计学意义（P>0.05）；同时两组治疗后2年与本组治疗后6个月、1年相比，差异无统计学意义（P>0.05）。结论：根管治疗术治疗根尖周病即期及远期疗效均显著，而一次性根管治疗术能明显降低就诊次数，缩短疗程，值得临床推广应用。%Objective:To investigate application and the forward curative effect of the root canal therapy in treatment of periapical disease. Method:128 cases of periapical disease were randomly divided into observation group and control group,64 cases in each group,the observation group takes one-off root canal therapy,the control group adopted routine repeatedly,root canal treatment,compared two groups of patients after treatment of clinical curative effect and the forward curative effect.Result:Observation group treatment the total effective rate was 91.55%,control group was 89.04%, compared two groups there was no statistically significant difference(P>0.05);6 months following observation group the total effective rate was 90.14%, 87.32%1 year,2 years was 84.51%,control group were 87.67%,86.30%,83.56%,during the same period there was no statistically significant difference comparing the two groups(P>0.05);At the same time the two groups after treatment for 2 years and 6 months after treatment,1 year,there was no statistically significant difference(P>0.05).Conclusion:For the treatment of root canal therapy on periapical disease spot and the forward curative effect significantly,and one-off root canal therapy can significantly reduce the number of visits,shorten the treatment course,worthy of clinical popularization and application.
