The purpose of this study was to evaluate the sealing properties of four root canal sealers. Forty-eight maxillary central incisors were instrumented with Profile rotary instruments. They were randomly divided into four groups (n = 12) and filled using lateral condensation with one of the four sealers: Sealapex, Pulp Canal Sealer, AH 26, and Ketac-Endo. The apical leakage was measured with a fluid filtration method and expressed as L s(-1) KPa(-1). The teeth filled with Sealapex displayed a higher apical leakage (8.42 +/- 4.2 10(-11) L s(-1) KPa(-1)) than those filled with AH 26 (2.10 +/- 1.39 10(-11) L s(-1) KPa(-1)), Pulp Canal Sealer (0.17 +/- 0.09 10(-11) L s(-1) KPa(-1)) or Ketac-Endo (0.32 +/- 0.24 10(-1) L s(-1) KPa(-1)) (p < 0.01). No statistically significant difference was found among AH 26, Pulp Canal Sealer, and Ketac-Endo. No correlation was found between the sealing efficiency of the four sealers and their adhesive properties recorded in a previous study.
本研究的目的是评估四种根管封闭剂的封闭性能。使用Profile旋转器械对48颗上颌中切牙进行预备。将它们随机分为四组（n = 12），并采用侧向加压法用四种封闭剂之一进行充填：Sealapex、牙髓根管封闭剂、AH 26和Ketac-Endo。采用液体过滤法测量根尖微渗漏，并以L s(-1) KPa(-1)表示。与用AH 26（2.10 +/- 1.39×10(-11) L s(-1) KPa(-1)）、牙髓根管封闭剂（0.17 +/- 0.09×10(-11) L s(-1) KPa(-1)）或Ketac-Endo（0.32 +/- 0.24×10(-11) L s(-1) KPa(-1)）充填的牙齿相比，用Sealapex充填的牙齿显示出更高的根尖微渗漏（8.42 +/- 4.2×10(-11) L s(-1) KPa(-1)）（p < 0.01）。在AH 26、牙髓根管封闭剂和Ketac-Endo之间未发现统计学上的显著差异。在先前一项研究中记录的四种封闭剂的封闭效率与其粘结性能之间未发现相关性。
