Fluoride Transfer Research Articles

Placenta and salivary gland fluoride transfer in the rat.

ConclusionsWhen pregnant rats receive 50 ppm F/day during entire pregnancy, their pups' molar teeth show a significant reduction in acid solubility. If fluoride administration is continued during lactation, no added anti-solubility effect is shown. Saliva either inactivates fluoride or salivary tissue is selective against fluoride secretion.
