The purpose of this study was to assess the apical sealing ability of the new resin-based Epiphany-Resilon root canal filling system, and to compare this with the sealing abilities of different pairings of AH plus, gutta-percha, Epiphany, and Resilon. Seventy extracted human single-rooted teeth were used. All teeth were instrumented using a set of ProTaper rotary instruments. The canal spaces were filled with different combinations of core and sealer using lateral condensation, as follows: group 1, AH Plus + gutta-percha; group 2, AH Plus + Resilon; group 3, Epiphany + Resilon; group 4, Epiphany + gutta-percha. Apical leakage quantity was measured with the computerized fluid filtration meter. Statistical analysis indicated that Epiphany gutta-percha combination had the least amount of microleakage than all the other groups; AH Plus gutta-percha combination proved to have second least amount of microleakage among the groups. AH Plus-Resilon combination demonstrated the greatest amount of microleakage. There were a significant difference between Epiphany gutta-percha and AH Plus-Resilon combinations (p < 0.05). It was found that there were no significant differences between Epiphany-Resilon combination and all the other groups (p > 0.05).
本研究的目的是评估新型树脂基Epiphany-Resilon根管充填系统的根尖封闭能力，并将其与AH plus、牙胶、Epiphany和Resilon不同组合的封闭能力进行比较。使用了70颗拔除的人单根牙。所有牙齿均使用一套ProTaper旋转器械进行预备。采用侧向加压法，用不同的核心材料和封闭剂组合充填根管，具体如下：第1组，AH Plus+牙胶；第2组，AH Plus+Resilon；第3组，Epiphany+Resilon；第4组，Epiphany+牙胶。用计算机化流体过滤仪测量根尖渗漏量。统计分析表明，Epiphany与牙胶的组合微渗漏量比所有其他组都少；AH Plus与牙胶的组合微渗漏量在各组中排第二少。AH Plus与Resilon的组合微渗漏量最大。Epiphany与牙胶的组合和AH Plus与Resilon的组合之间存在显著差异（p<0.05）。发现Epiphany与Resilon的组合与所有其他组之间无显著差异（p>0.05）。
