Abstract
The study contains the results of fluoride testing done on 31 fetal specimens. It demonstrates that fluoride can pass through the placenta into the fetus, that bone tissues shows the highest levels of fluoride while brain tissue shows the lowest, and that overall level of fluoride increases with the fluoride burden of the mother and the age of the fetus.
