A new dye-diffusion test method was utilized to evaluate the microleakage between amalgam and composite resin. An amalgam cylinder was made to which a base of composite was added. The effects of several factors upon the microleakage were investigated. The test results indicated less microleakage when bonding agent was applied directly to the roughened amalgam prior to placement of composite resin. The most microleakage was found when roughened amalgam surface was acid-etched before placement of bonding agent and composite resin.
采用一种新的染料扩散试验方法来评估汞合金与复合树脂之间的微渗漏情况。制作了一个汞合金圆柱体，并在其上添加了复合树脂基底。研究了几个因素对微渗漏的影响。试验结果表明，在放置复合树脂之前，直接将粘结剂应用于粗糙的汞合金表面时，微渗漏较少。在放置粘结剂和复合树脂之前对粗糙的汞合金表面进行酸蚀时，发现微渗漏最为严重。
