摘要： 目的分析生物根管封闭剂iRoot SP在扁形根管根尖封闭中的性能,为临床工作提供指导。方法取48颗根管的近远中径与颊舌径之比小于0.5的单根管离体前磨牙,根管预备后,随机分为A、B、C 3组,每组各16颗。分别选用Vitapex（A组）、AH Plus（B组）、iRoot SP（C组）作为根管封闭剂,结合连续波热牙胶垂直充填技术进行根管充填。所有样本经根尖染料渗透实验,采用透明牙技术,比较3组离体牙微渗漏情况,评价iRoot SP在扁形根管根尖封闭中的性能。采用SPSS19.0软件包对数据进行统计学分析。结果A组染料渗入深度显著大于B、C组,差异具有显著性（P<0.05）;B、C组染料渗入深度相比,无显著差异（P>0.05）。结论iRoot SP和AH Plus在扁形形根管根尖封闭中的性能接近,效果优于Vitapex根管充填糊剂。

Abstract: To investigate the sealing ability of biological root canal sealer iRoot SP in over-root canal filling. METHODS：After completion of root canal preparation, 48 extracted human single-canal teeth were used. The ratio of mesio-distal root canal diameter to bucco-lingual diameter was less than 0.5. The teeth were randomly divided into group A, B and C. The root canals were obturated with root canal filling agent (group A), AH Plus (group B) and iRoot SP (group C), respectively; the apical leakage was evaluated by dye penetration method and transparent teeth technique. The data were analyzed using SPSS 19.0 software package. RESULTS: The depth of dye penetration in group A was significantly higher than that in group B and C (P<0.05); there was no significant difference in the depth of dye penetration between group B and group C (P>0.05). CONCLUSIONS: The apical sealing ability of iRoot SP is equivalent to AH Plus in oval-root canal, both are better than that of root canal filling agent．
