title: [Influence of dental amalgams on the concentration of mercury and silver in biological fluids and hair (author's transl)].
abstract: 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.
