显微外科与传统外科根尖手术治疗慢性根尖周炎的疗效比较

Efficacy Comparison of Endodontic Microsurgery and Traditional Endodontic Surgery for Chronic Apical Periodontitis

目的:比较显微外科与传统外科根尖手术治疗慢性根尖周炎的疗效。方法:行根尖手术治疗的慢性根尖周炎患者68例,根据器械材料和手术方式不同分为2组:显微外科根尖手术组36例,采用无机三氧化聚合物(mineral trioxide aggregate,MTA)根尖倒充填;传统外科根尖手术组32例,采用银汞根尖倒充填。通过临床和X线片随访评价术后疗效,术后2年比较治疗成功率。结果:显微外科根尖手术治疗组成功率为91.67%,传统外科根尖手术组治疗成功率为71.88%,2组差异有统计学意义(P<0.05)。结论:显微外科根尖手术对慢性根尖周炎的治疗效果明显优于传统根尖手术。

AbsTo compare the efficacies of endodontic microsurgery and traditional endodontic surgery for chronic apical periodontitis. Methods： A total of 68 cases who had endodontic surgery for chronic apical periodontitis were involved. According to the different instruments and surgical treatments, these cases were divided into two groups, one group of endodon tic microsurgery （36 cases）, filled with mineral trioxide aggregate （MTA）; the other group of traditional endodontic surgery （32 cases）, filled with amalgam. The efficacies were evaluated by clinical and radiographic checkups. According to the results of the checkups,compared the success rates of the two groups after two years. Results： There was a significant difference in the success rate between the group of endodontic microsurgery （91.67%） and the group of traditional endodontic surgery （71.88%） after two years （P〈0.05）. Conclusions： Endodontic microsurgery is superior to traditional endodontie surgery.
