摘　　要：目的观察显微根尖术治疗难治性慢性根尖周炎的临床效果。方法选取2015年9月至2018年3月陕西省宝鸡市人民医院口腔科就诊的150例难治性慢性根尖周炎患者,按随机数字表法分为75例显微治疗组和75例常规治疗组,术后随访1年,观察比较两组手术方式的临床治疗总有效率,术前和术后6、12个月根尖周指数(PAI)的变化情况。结果随访1年后,显微治疗组患者临床治疗总有效率显著高于常规治疗组,差异有统计学意义(P<0.05)。显微治疗组术后6、12个月PAI低于常规治疗组,差异有统计学意义(P<0.05)。结论显微根尖术相比于常规根尖术治疗难治性慢性根尖周炎效果较好,患者根尖周评价良好,建议临床推广。Objective To observe the clinical effect of micro apical surgery in the treatment of refractory chronic periapical periodontitis.Methods From September 2015 to March 2018,150 patients with refractory chronic periapical periodontitis were selected from the stomatology department of a hospital.They were divided into 75 cases of micro therapy group and 75 cases of conventional therapy group according to the method of random number table.After one year's follow-up,the total effective rate of the two groups was observed and compared,and the changes of periapical index(PAI)before and 6 and 12 months after the operation were observed and compared.Results After one year's follow-up,the total effective rate of micro therapy group was higher than conventional therapy group,the difference was statistically significant(P<0.05).The PAI of the micro therapy group was lower than conventional therapy group at 6 and 12 months after operation,the difference was statistically significant(P<0.05).Conclusion Compared with conventional apical surgery,micro apical surgery has effects in the treatment of refractory chronic periapical periodontitis,and the periapical evaluation of patients is good,which is recommended to be popularized clinically.
