Investigation into the mother's history often indicates amalgam treatment during pregnancy, repeated immunization with thiomersal-containing vaccines, or high fish consumption as seen in Asian countries.
The amount of amalgam treatment was characterized by the number of amalgam surfaces placed at baseline (i.e., within 1 year from the first visit) and during the follow-up period.
Mean urinary mercury concentrations for male and female participants were similar at baseline, but increases after amalgam treatment were larger for females than for males.
To our knowledge, this is the first study to describe urinary mercury excretion patterns in children during the longitudinal course of amalgam treatment from childhood through adolescence and to quantify the relationship between amalgam surfaces and urinary mercury concentrations during the course of treatment.
These differences held up after adjustment for creatinine and differences in the amount of amalgam treatment received (Table 2).
The mean urinary mercury concentration in that cohort of adults, 1.7 [micro]g/g creatinine, was higher than the mean concentration of 0.9 [micro]g/g creatinine among the children in the amalgam treatment group in our trial 5 years after placement of their first amalgam restorations.
