【摘 要】目的 分析在恒牙根尖周炎伴根尖孔敞開病例中应用Ⅰ root BP plus根尖屏障术治疗的临床效果。方法 选取2020年3月-2021年3月我院收治的40例慢性根尖周炎伴根尖孔敞开患者为研究对象，随机分为对照组与试验组，各20例。对照组行MTA根尖屏障术，试验组行Ⅰ root BP plus根尖屏障术，比较两组操作时间、临床疗效及不良反应发生情况。结果 试验组操作时间为（6.56±1.23）min，短于对照组的（10.23±1.45）min，差异有统计学意义（P<0.05）；试验组治疗总有效率为95.00%，高于对照组的90.00%，但差异无统计学意义（P>0.05）；试验组不良反应发生率为5.00%，低于对照组的10.00%，但差异无统计学意义（P>0.05）。结论 Ⅰ root BP plus与MTA均为根尖屏障术的根尖封闭剂，两者在临床疗效及安全性上无显著差异，但Ⅰ root BP plus的操作性能更好，可缩短治疗时间。

【Abstract】Objective To evaluate the clinical efficacy of Ⅰ root BP plus apical barrier technique in the treatment of periapical periodontitis of permanent teeth with open apical foramen. Methods From March 2020 to March 2021， 40 patients with periapical periodontitis of permanent teeth with open apical foramen in our hospital were selected as the research objects， and they were randomly divided into control group and experimental group， with 20 patients in each group. The control group was treated with MTA root tip barrier， and the experimental group was treated with Ⅰ root BP plus apical barrier technique. The operation time， clinical efficacy and adverse reactions were compared between the two groups. Results The operation time of the experimental group was （6.56±1.23） min， which was shorter than （10.23±1.45） min of the control group， and the difference was statistically significant （P<0.05）. The total effective rate of treatment in the experimental group was 95.00%， which was higher than 90.00% in the control group， but the difference was not statistically significant （P>0.05）. The incidence of adverse reactions in the experimental group was 5.00%， which was lower than 10.00% in the control group， but the difference was not statistically significant （P>0.05）. Conclusion Both Ⅰ root BP plus and MTA are apical sealers for apical barrier technique， while there is no significant difference in clinical efficacy and safety between the two， but Ⅰ root BP plus has better performance and can shorten the treatment time.

根管治疗术（root canal therapy，RCT）是牙髓病和根尖周病的有效手段，也是目前该疾病治疗的首选方案。根管治疗术成功的关键就是根管内严密封闭的无菌环境，但临床上较多病例由于各种原因致使根尖孔未闭合，在根管治疗中不能形成良好的根尖止点而造成微渗漏，影响了根管治疗的预后。随着无机三氧化聚合物（MTA）和生物陶瓷制剂（Ⅰ root BP plus）在口腔中的广泛应用，是根尖孔敞开恒牙的新方案，目前最常用的根尖屏障材料为MTA，可有效缩短患牙治疗时间，且远期疗效较为确切[1]。根尖屏障术（apical barrier technique）作为一种非手术方式，通过在根管根尖部填充生物相容材料，在根尖部形成根尖止点，达到根尖封闭的效果[2]。但M……
