Abstract
Fluoride retention is high during fluoride supplementation and increases with increasing fluoride intake. When large amounts of fluoride were given for several months the retention of fluoride was about the same as in the initial phase of fluoride supplementation, whether the supplemental dose of fluoride was 10, 20, or 45 mg per day. The rapid return of the fluoride balance to control values after the high fluoride intake was discontinued indicates that there is not only a tendency for continued retention of fluoride during the high fluoride intake but also after large amounts of fluoride have already been retained

No evidence of transfer of fluoride from plasma to breast milk.
Artificially fluoridated drinking water is supplied throughout the world as a mass-prophylactic against dental caries. No data are available, however, on the transfer of fluoride from maternal plasma to breast milk. We have therefore compared the fluoride concentration in the plasma and breast milk of nursing mothers after an oral

A mathematical model for fluoride uptake by the skeleton
A mathematical model was developed that predicts fluoride accumulation and clearance from the skeleton based upon fluoride bioavailability, bone remodeling rate, and the fluoride binding characteristics of bone. It was assumed that fluoride binds to bone in a nonlinear fashion such that a smaller percentage of fluoride is bound to

Fluoride and calcium levels in the aorta
Among soft tissue organs which store fluoride (F-), the aorta contains the highest levels. [1-2]. Calcifications of arteries of the Monckeberg type have been reported in relatively young persons afflicted with skeletal fluorosis from endemic areas. [3-5] It was, therefore, of interest to determine whether or not there is a

Pharmacokinetics of fluoride in man and its clinical relevance
A large number of parameters will influence and mediate the activity and the pharmacological response of dental fluoride products after systemic or topical treatment. This report reviews some aspects of the pharmacokinetics of fluoride in man, fluoride bio-availability, plasma kinetics, and kinetics of fluoride in saliva and plaque fluid. Pharmacokinetic

Fluoride absorption: independence from plasma fluoride levels
The concept that there are physiologic mechanisms to homeostatically regulate plasma fluoride concentrations has been supported by results in the literature suggesting an inverse relationship between plasma fluoride levels and the absorption of the ion from the gastrointestinal tract of the rat. The validity of the relationship was questioned because
