The aim of this study was to compare the leakage of root canal fillings of gutta-percha or Resilon cones in association with AH Plus or Epiphany sealer.
Four groups of premolars (n = 64) were instrumented to size 45/.04 ProFile and filled with laterally compacted gutta-percha cones or Resilon cones in association with AH Plus or Epiphany sealer. The specimens were stored for 2 weeks at 37 degrees C and 100% humidity. After that, leakage was measured using the fluid filtration method and determined as microL/min.10 psi.
Homogeneity of variance and multiple comparisons tests were performed and indicated that root fillings with the combination of gutta-percha cones and AH Plus sealer showed lower leakage values (P < .05) than the other groups.
Considering the experimental conditions and the results obtained, it was concluded that fillings made with gutta-percha cones in combination with AH Plus sealer had the best performance.
本研究旨在比较牙胶尖或Resilon牙胶尖联合AH Plus或Epiphany封闭剂时根管充填物的微渗漏情况。
四组前磨牙（n = 64）预备至45/.04 ProFile规格，并用侧向加压法充填牙胶尖或Resilon牙胶尖联合AH Plus或Epiphany封闭剂。标本在37℃、100%湿度下保存2周。之后，采用液体过滤法测量微渗漏，并以微升/分钟·10磅力/平方英寸为单位确定渗漏值。
进行了方差齐性检验和多重比较检验，结果表明，牙胶尖联合AH Plus封闭剂的根管充填物渗漏值低于其他组（P <.05）。
考虑到实验条件和所得结果，得出结论：牙胶尖联合AH Plus封闭剂的充填物性能最佳。
