The purpose of this study was to compare the sealing ability of gutta-percha and AH Plus sealer versus Resilon and Epiphany Resin Root Canal sealer using three different final irrigants with the fluid filtration model. There were 140 teeth prepared using a crown-down method to a size 50 file. The teeth were randomly divided into two groups: (A) GP and AH Plus and (B) Resilon and Epiphany. After removal of the smear layer each group was irrigated with either 5.25% NaOCl, 0.012% chlorhexidine (CHX), or 2% CHX for 10 minutes. Obturation was performed using the continuous wave of condensation. The teeth were stored for 20 days in 100% humidity before testing. Two-way ANOVA analysis indicated significantly less leakage (p < 0.05) using Resilon with Epiphany sealer compared to gutta-percha and AH Plus sealer. There was no statistical significance between any of the irrigants used for either obturation group.
本研究的目的是使用流体过滤模型，比较牙胶尖与AH Plus封闭剂、Resilon与Epiphany树脂根管封闭剂在三种不同的最终冲洗液作用下的封闭能力。使用冠向下法将140颗牙齿预备至50号锉。将牙齿随机分为两组：（A）牙胶尖与AH Plus组；（B）Resilon与Epiphany组。去除玷污层后，每组分别用5.25%次氯酸钠、0.012%氯己定（CHX）或2% CHX冲洗10分钟。采用连续波热凝法进行充填。在测试前，将牙齿在100%湿度下储存20天。双向方差分析表明，与牙胶尖和AH Plus封闭剂相比，使用Resilon与Epiphany封闭剂时渗漏显著减少（p < 0.05）。对于任何一组充填剂，所使用的冲洗液之间均无统计学差异。
