摘　　要：目的:评价并比较2种充填系统Resilon/Epiphany Self-Etch和牙胶/AH plus的根尖封闭能力。方法 :选取34颗新鲜拔除的单直根管下颌前磨牙。6颗作为阴性和阳性对照组,28颗随机分为2组(每组14颗),预备至同一标准。分别采用2种充填系统Resilon/Epiphany Self-Etch和牙胶/AH plus充填根管,通过印度墨汁渗透试验比较各组的根尖微渗漏。采用SPSS13.0软件包对数据进行统计学分析。结果:2种充填系统的根尖微渗漏有显著性差异,Resilon/Epiphany SE组的渗漏较低(P<0.05)。Resilon/Epiphany SE中封闭剂Epiphany SE通过形成树脂突与牙本质及核心充填材料Resilon紧密黏结,形成一体化结构(mono-block)。结论:Resilon/Epiphany SE充填系统的根尖封闭性能优于传统牙胶充填材料,且封闭剂Epiphany SE与核心充填材料Resilon及根管内结构产生化学性黏结,形成一体化结构。PURPOSE： To compare the apical sealing ability of the two filling materials： Resilon/Epiphany Self-Etch and Gutta-percha / AH plus. METHODS： Thirty-six recently extracted mandibular premolar roots were included, 6 for the positive and negative groups, 28 for the experimental groups （14 for the Resilon/Epiphany SE group, 14 for the Gutta- percha / AH plus group）.The roots were prepared according to the same standards, then the root canals were filled respectively with Resilon/Epiphany SE and Gutta-percha/AH plus. The teeth were put into the India ink to stain, and the apical sealing ability of the two filling materials： Resilon/Epiphany Self-Etch and Gutta-percha/AH plus were compared with the methods of dye leakage. SPSS13.0 software package was used for data analysis. RESULTS： The sealer of the Resilon/Epiphany SE was bonding to the resin filling material and the root canal dentin, and became a structure named mono-bloek. Compared with the Gutta-percha/AH plus group, the Resilon/Epiphany SE group had significantly lower apical leakage （P〈0.05）. CONCLUSIONS： The results show that the Resilon/Epiphany SE filling system has better apical sealing ability than the traditional filling material of Gutta-percha/AH plus, and the sealer of Resilon/Epiphany SE is bonded to the resin filling materials and the root canal dentin, and become a structure named monoblock.
