PURPOSE
To assess the apical sealing property of a new root canal filling material, Epiphany.
METHODS
Seventy extracted maxillary and mandibular single-rooted teeth were used. They were randomly divided into three groups and obturated by lateral condensation with gutta-percha and AH 26/AH Plus sealers and Resilon core material and Epiphany sealer. Apical leakage was measured by the fluid-transport method.
RESULTS
The differences in leakage among gutta-percha with AH 26, gutta-percha with AH Plus, and Resilon with Epiphany were statistically significant (P < 0.05). The teeth filled with gutta-percha/AH 26 displayed the most apical leakage. There were no differences between the Resilon/Epiphany and gutta-percha/AH Plus groups (P > 0.05).
目的
评估一种新型根管充填材料Epiphany的根尖封闭性能。
方法
使用70颗拔除的上颌和下颌单根牙。将它们随机分为三组，分别用牙胶尖侧向加压充填并配合AH 26/AH Plus封闭剂、Resilon核心材料和Epiphany封闭剂进行充填。采用液体渗透法测量根尖微渗漏。
结果
牙胶尖配合AH 26、牙胶尖配合AH Plus以及Resilon配合Epiphany之间的渗漏差异具有统计学意义（P < 0.05）。充填牙胶尖/AH 26的牙齿根尖微渗漏最为明显。Resilon/Epiphany组和牙胶尖/AH Plus组之间无差异（P > 0.05）。
