The amounts of copper, mercury, silver or zinc released from two brands of freshly prepared, lathe cut amalgams and from one brand of dispersed phase type amalgam into artificial saliva have been measured. Samples were immersed in the solution a few minutes after the end of trituration and exposed statically for periods of up to about 4 days. The initial mercury release from such specimens could exceed the long term mercury release from old amalgams by more than two orders of magnitude. The measurements indicate that during the first day after insertion of two amalgam fillings, each with an assumed surface area of 1 cm2 and under presumably static conditions, mercury at the level of more than twice the mercury food and drink intake could be released in the oral cavity. This is, however, a situation which appears infrequently, e.g. following dental treatment once a year. The amounts of copper and zinc released initially were considerably lower than the corresponding food and drink intake values, while silver might be on the same level. The measurements were conducted using nuclear tracer techniques.
已对两种品牌新制备的车削汞合金以及一种品牌的分散相型汞合金释放到人工唾液中的铜、汞、银或锌的量进行了测量。在研磨结束后几分钟将样品浸入溶液中，并静态暴露长达约4天。此类标本最初的汞释放量可能比旧汞合金的长期汞释放量高出两个多数量级。测量表明，在植入两个假定表面积为1平方厘米的汞合金填充物后的第一天，在大概静态的条件下，口腔中释放的汞量可能超过汞在食物和饮料中的摄入量的两倍以上。然而，这种情况很少出现，例如每年进行一次牙科治疗之后。最初释放的铜和锌的量远低于相应的食物和饮料摄入量值，而银的量可能与之相当。这些测量是使用核示踪技术进行的。
