[Normal and induced Hg release from different amalgams].
In an experimental investigation of 20 subjects who had no amalgam fillings, the mercury load from artificially applied, standardised amalgam surfaces was tested for one product containing gamma-2 and one free of gamma-2 respectively. The product which contained gamma-2 caused a statistically significant increase in Hg concentrations in the 24-hour urine sample. After challenge with Dimaval, an intensifying effect on the elimination rate could be detected, although all values clearly remained below a toxicologically relevant concentration. In order to avoid unnecessary exposure to heavy metals, the use of gamma-2-free amalgams and, in the long term, the development of optimised filling materials and intensification of prophylactic measures for prevention of dental caries are to be welcomed.
