| 摘 要： | 目的：探讨iRootBP作为根尖倒充填材料在根尖手术中的疗效。方法：对形成根尖周炎的比格犬（beagle犬）的下颌前磨牙行显微根尖手术，60个根管随机分为2组，分别用iRootBP和MTA作为根尖倒充填材料。根据x线片判定标准评价术后疗效，统计术后1年手术成功率。结果：术后1年的成功率，iRootBP为90％，MTA为93％，两种材料的疗效比较无统计学差异。结论：作为倒充填材料，iRootBP与MTA的临床效果类似。

| Abstract: | Objective： To evaluate the effect of iRoot BP as root--end filling materials during periapical microsur- gery in animals. Methods： The mandibular premolars of 5 beagle dogs were selected for study. Experimentally peri- apical lesions in teeth of dogs were induced , root canal therapy and micro--surgery were made. 60 canals were di- vided into two groups,iRoot BP or MTA was randomly used as root--end filling materials. The success rate of 12 months post--operatively was statistical analysed according to imageology. Results： The success rate of iRoot BP was 90% and that of MTA was 93% in 12 months post--operatively. The success rate of of iRoot BP was not sig- nificantly different with that of MTA. Conclusion： As root--end filling materials in amimal study, MTA and iRoot BP had the similar clinical effectiveness. |
