title: [Mercury concentrations in blood and urine before and after placement of non-gamma 2 amalgam fillings].
abstract: The object of the study was to determine whether mercury concentrations in blood and urine were increased directly after placement of non-gamma 2-amalgam fillings. Our cohort consisted of 45 subjects, male and female, age between 19 and 45 years, who had amalgam fillings and were not exposed to mercury on their jobs. Thirty subjects received non-gamma 2-amalgam fillings, 15 did get new fillings. Cold, flameless atom absorption spectrometry was used to analyze mercury levels in blood and urine samples before and for 24 hours after placement of the amalgam fillings at one hour intervals. Mercury concentrations in blood (before and after) and - before placement of new non-gamma 2-amalgam fillings - in urin were below the normal upper limit in all 45 subjects. Mercury concentrations in urin after placement of new fillings did not show any increase over 24 hours. Median values varied between 1.0 and 2.1 micrograms Hg/g creatinine and thus were also within the normal range.
