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

Plasma and developing enamel fluoride concentrations during chronic acid-base disturbances
Mild acid-base disturbances were induced in rats for 30 days. These disturbances did not affect % ash of maxillary incisors or % P of the developing enamel from mandibular incisors. Total fluoride intake (food and water) among groups drinking fluoride-free water was constant. Nevertheless, average plasma and developing enamel fluroide

Fluoride metabolism
Knowledge of all aspects of fluoride metabolism is essential for comprehending the biological effects of this ion in humans as well as to drive the prevention (and treatment) of fluoride toxicity. Several aspects of fluoride metabolism - including gastric absorption, distribution and renal excretion - are pH-dependent because the coefficient

Assessment of the influence of meal type on fluoride absorption due to ingestion of professionally applied gels
AIMS: The aim of this study is to assess the influence of eating, prior to application of professionally used gels, on the rate of fluoride absorption due to the ingestion of 1.23% acidulated phosphate fluoride (APF). MATERIALS AND METHODS: After fasting for 12 hours, 16 adult volunteers (> 65 kg) ingested

Sodium Fluoride F 18: Summary of Use during Lactation.
Drug Levels and Effects Information in this record refers to the use of sodium fluoride F 18 as a diagnostic agent. The manufacturer recommends withholding breastfeeding for 24 hours after a diagnostic dose of 300-450 MBq (8 to 12 mCi); however, this time might be longer than necessary given the minimal

Relationship between daily fluoride intake from diet and the use of dentifrice and human plasma fluoride concentrations
The literature contains reports of the relationship between the fluoride concentrations in drinking water and human plasma. None of these studies, however, documented individual levels of daily fluoride intake, which can vary considerably among individuals served by the same water supply. Furthermore, while water can be an important source of
