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。PURPOSE： 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.
