Allindividuals were dentally examined, interviewed for occupational and food load of mercury andsamples of urine and breast milk were analysed for mercury levels. Filling of teeth whennecessary were provided by composite and glassionomer filling materials. In 24 patients therewas necessary to grind out old and damaged amalgam fillings while in other n 8 patients onlyprimarily decayed teeth had to be treated.
