根尖屏障技术治疗难治性根尖周炎的临床效果

The Clinical Effect of Apical Barrier Technique in the Treatment of Refractory Periapical Periodontitis

目的观察iRoot BP Plus根尖屏障技术治疗成人难治性根尖周炎的临床效果。方法选取2017年1月~2019年8月来我院口腔科需根管再治疗的患者作为研究对象,共需根管再治疗患牙59个,随机分为试验组(30个)和对照组(29个),两组均常规去除原充填物,超声荡洗根管,机用镍钛锉预备至06/25#,试验组扩大根尖孔至大于30#,根管内封VITAPEX糊剂消毒,以iRoot BP Plus严密充填根尖段5 mm根管,热牙胶充填上段根管;对照组不扩大根尖孔,AH-PLUS加热牙胶充填根管;比较两组临床效果。结果术后3个月,试验组成功率为76.67%,对照组为48.28%,差异有统计学意义(P<0.05);术后半年,试验组成功率为73.33%,对照组为44.83%,差异有统计学意义(P<0.05)。结论使用iRoot BP Plus根尖屏障技术治疗成人难治性根尖周炎可获得较为满意的疗效,值得临床应用。

Objective To observe the clinical effect of iRoot BP Plus apical barrier technology in the treatment of refractory apical periodontitis in adults.Methods The patients who came to our hospital's Department of Stomatology from January 2017 to August 2019 who needed root canal retreatment were selected as the research objects.A total of 59 teeth who needed root canal retreatment were randomly divided into experimental group(30)and control group(29),both groups were routinely removed the original fillings,the root canals were washed with ultrasonic wave,and prepared with rotary nickel-titanium files to 06/25#.The test group enlarged the apical foramen to more than 30#,and the root canal was disinfected with VITAPEX paste,iRoot BP Plus was used to tightly fill the 5 mm root canal of the apical section,and the upper root canal was filled with warm gutta-percha;the control group did not expand the apical foramen,and the AH-PLUS with heated gutta-percha was used to fill the root canal;the clinical effects of the two groups were compared.Results Three months after the operation,the test composition power was 76.67%,and the control group was 48.28%,the difference was statistically significant(P<0.05);six months after the operation,the test composition power was 73.33%,and the control group was 44.83%,the difference was statistically significant(P<0.05).Conclusion The iRoot BP Plus root apical barrier technology could achieve satisfactory results in the treatment of refractory periapical periodontitis in adults and was worthy of clinical application.
