摘　　要：目的:比较iRoot SP与AH plus 2种根管封闭剂的根尖封闭效果。方法:选择50颗近期拔除的单根管牙,随机分为2个实验组A、B(每组20颗),2个对照组C、D,C组为阳性对照组(n=5),D组为阴性对照组(n=5)。使用机用Protaper预备所有根管至F2,分别采用iRoot SP根管封闭剂加连续波充填技术(A组)、AH Plus根管封闭剂加连续波热充填技术(B组)充填根管。采用染料渗透法检测根尖微渗漏,对染料渗透的长度进行测量,采用SPSS13.0软件包对数据进行统计学分析。结果:实验组A、实验组B、阳性对照组C、阴性对照组D的微渗透值分别为(1.46±0.21)mm、(1.52±0.22)mm、(10.75±1.28)mm、0 mm。实验组B的微渗漏值高于实验组A,但2组间无显著差异。结论:根管封闭剂iRoot sp的根尖封闭性能与AH Plus相似。PURPOSE：To evaluate the apical sealing ability of two root canal sealers. METHODS： Fifty recently extracted human anterior teeth with a single canal （α〈5; Schneider＇s method） were divided randomly into two experimental groups （twenty teeth in each group）, as well as positive and negative control group （five teeth in each group）. The root canals were instrumented using Protaper file to F2, and were obturated with iRoot SP with continuous wave obturation technique （group A）, AH plus with continuous wave obturation technique （group B）. The apical microleakage was evaluated by dye penetration method. Linear dye penetration was measured and analyzed by SPSS13.0 software package. RESULTS： Mean depth of leakage for groups with the smear layer intact was （1.46±0.21） mm for group A, （1.52±0.22） mm for group B, （10.75±1.28） mm for positive control group, and 0 mm for negative control group. The value of the experimental group B was greater than group A, but there was no significant difference between the 2 groups. CONCLUSION： iRoot SP displays similar in vitro apical sealing ability to AH plus. Supported by National Science Foundation of Liaoning Province（201102250）.
