BACKGROUND Successful endodontic therapy requires a fluid-tight apical seal. The aim of this in vitro study was to evaluate and compare the apical sealing ability of 3 root canal sealers: Apexit Plus, AH Plus, and Resilon/Epiphany sealers. MATERIAL AND METHODS Samples of 152 single-rooted teeth were divided into 2 test groups, and each group was divided into 3 subgroups based on the preparation and obturation technique. After preparation with the step-back technique, the first group of root canals were obturated with lateral gutta-percha compaction in combination with AH Plus sealer or Apexit Plus or with the Resilon/Epiphany system alone. In the second group, preparation was done with the crown-down technique and root canals were then obturated with Thermafil obturator in combination with AH Plus or Apexit Plus or with Resilon/Epiphany sealer alone. Apical leakage was determined using a dye leakage test observed with a stereomicroscope. The degree of dye leakage was assessed using the t test to comparing the arithmetic averages of the groups. RESULTS In the groups prepared with the step-back technique, the average dye leakage was lower in samples obturated with Resilon/Epiphany, than in those filled with AH Plus/lateral gutta-percha compaction or Apexit Plus/lateral gutta-percha compaction. In groups prepared with the crown-down technique and obturated with the Resilon/Epiphany system, the average dye leakage was lower than in those filled with AH Plus/Thermafil obturation and those filled with Apexit Plus/Thermafil obturation. CONCLUSIONS Although all preparation and obturation techniques showed dye penetration, the crown-down technique paired with the Resilon/Epiphany system showed the least leakage.
背景 成功的根管治疗需要根尖形成液密性封闭。本体外研究的目的是评估和比较三种根管封闭剂的根尖封闭能力：Apexit Plus、AH Plus和Resilon/Epiphany封闭剂。材料与方法 将152颗单根管牙样本分为2个试验组，每组根据预备和充填技术再分为3个亚组。采用逐步后退技术预备后，第一组根管分别用侧向热牙胶加压充填联合AH Plus封闭剂或Apexit Plus封闭剂，或仅用Resilon/Epiphany系统充填。第二组采用冠向下技术预备，然后分别用Thermafil充填器联合AH Plus或Apexit Plus封闭剂，或仅用Resilon/Epiphany封闭剂充填根管。使用立体显微镜观察染料渗漏试验来确定根尖微渗漏情况。采用t检验比较各组算术平均值来评估染料渗漏程度。结果 在采用逐步后退技术预备的组中，用Resilon/Epiphany系统充填的样本平均染料渗漏低于用AH Plus/侧向热牙胶加压充填或Apexit Plus/侧向热牙胶加压充填的样本。在采用冠向下技术预备并使用Resilon/Epiphany系统充填的组中，平均染料渗漏低于用AH Plus/Thermafil充填和用Apexit Plus/Thermafil充填的组。结论 尽管所有预备和充填技术均显示有染料渗透，但冠向下技术联合Resilon/Epiphany系统显示渗漏最少。
