In an in vitro study, the use of sealers and liners (Fuji varnish, Vitrabond, Vitremer, Paama 2, All-Bond 2, or Resinomer) significantly reduced the amount of marginal leakage around amalgam (Permite C or Lojic Plus) and gallium (Galloy) alloy restorations. This reduction in marginal leakage was produced by all sealers and liners tested, and there were no statistically significant differences between these materials. Unlined restorations of Permite C had significantly less marginal leakage than Galloy or Lojic Plus. Unlined Lojic Plus restorations had the greatest amount of marginal leakage. The experimental method used in the present study proved to be suitable for quantitative comparison of marginal leakage of different dental materials.
在一项体外研究中，使用封闭剂和衬层材料（富士玻璃离子水门汀、维他邦、玻璃离子粘固剂、帕马2、全粘结2或树脂单体）可显著减少汞合金（Permite C或Lojic Plus）和镓合金（Galloy）修复体周围的边缘微渗漏量。所有测试的封闭剂和衬层材料均能减少边缘微渗漏，且这些材料之间无统计学显著差异。未衬层的Permite C修复体的边缘微渗漏明显少于Galloy或Lojic Plus。未衬层的Lojic Plus修复体的边缘微渗漏量最大。本研究中使用的实验方法被证明适用于不同牙科材料边缘微渗漏的定量比较。
