The release rate of mercury from a conventional, a dispersed phase or a spherical high copper content amalgam under static conditions in stimulated or artificial saliva has been measured and found to decrease approximately exponentially with time. A higher initial release rate was observed for mercury in stimulated saliva than in artificial saliva during the in vitro experiments. In a pilot study corrosion current was recorded from an amalgam specimen immersed in saliva, and was found to decrease approximately exponentially with time. After brushing the surface of the amalgam during two subsequent periods, in a manner similar to toothbrushing, an increase in corrosion current was measured indicating the removal of loosely bound corrosion products. A model describing the periodical mercury release from an amalgam surface has been proposed.
在静态条件下，已对传统型、分散相型或球形高铜含量汞合金在刺激性唾液或人工唾液中的汞释放速率进行了测量，发现其随时间大致呈指数下降。在体外实验中，观察到刺激性唾液中汞的初始释放速率高于人工唾液中汞的初始释放速率。在一项初步研究中，记录了浸入唾液中的汞合金标本的腐蚀电流，发现其随时间大致呈指数下降。在随后两个阶段以类似于刷牙的方式刷汞合金表面后，测量到腐蚀电流增加，表明去除了松散结合的腐蚀产物。已提出了一个描述汞合金表面周期性汞释放的模型。
