The influence of the extraction and fixing of dental amalgams on the metallic concentrations of different biological samples was studied by atomic absorption spectrometry on a subject. The levels of mercury obviously increased in urine, saliva and slightly in blood, with a maximum on the second or third day after the intervention; on the other hand, in the hair, the increase was very low even at the end of 40 days. The urinary and salivary kinetics of silver were practically similar to the ones of mercury. The determination of silver in these fluids could reveal with more specificity the part of dental amalgams on the increase of the metallic biological concentrations. A study with 25 other subjects carrying amalgams permitted to put in evidence some factors facilitating a slight increase of the mercury contents of the saliva, urine and blood.
通过原子吸收光谱法对一名受试者研究了牙科汞合金的提取和固定对不同生物样品金属浓度的影响。尿液、唾液中的汞含量明显增加，血液中略有增加，在干预后的第二天或第三天达到最高值；另一方面，即使在40天结束时，头发中的汞含量增加也非常低。银在尿液和唾液中的动力学与汞的动力学实际相似。测定这些液体中的银可以更具体地揭示牙科汞合金对生物金属浓度增加的影响。对另外25名佩戴汞合金的受试者进行的一项研究发现了一些促使唾液、尿液和血液中汞含量略有增加的因素。
