Abstract

The fluoride content of drinking water is directly correlated with the serum and saliva fluoride. Serum fluoride levels are also directly related to those of saliva, but not to urinary fluoride.

These interrelations are so close that a mathematical formula can be devised for the calculation of fluoride in body fluids. For instance, a sample of saliva may serve for the quantification of serum fluoride. Whereas these interrelations are observed in general population groups they do not always apply to individuals.

  • Biomarkers for the Assessment of Fluoride Exposure in Children.

    Due to practical difficulties in quantifying fluoride exposure, the ability of various biomarkers to predict exposure has been investigated previously. However, the results are inadequate for validation of their application and usefulness. This study aimed to investigate the association between contemporary/recent biomarkers of fluoride exposure and total daily fluoride intake

  • Fluoride metabolism: its significance in water fluoridation.

    Excerpt The purpose of this report is the review of the present knowledge of the metabolism of fluorides, particularly in the human body, and the use of this knowledge in estimating the factors of safety in water fluoridation. In this discussion, many of the biological effects of fluorides (purported or well-established)

  • Skeletal fluorosis from brewed tea

    BACKGROUND:  High fluoride ion (F(-)) levels are found in many surface and well waters. Drinking F(-)-contaminated water typically explains endemic skeletal fluorosis (SF). In some regions of Asia, however, poor quality "brick tea" also causes this disorder. The plant source of brick, black, green, orange pekoe, and oolong tea, Camellia

  • Fatal cases of acute suicidal sodium and accidental zinc fluorosilicate poisoning. Review of acute intoxications due to fluoride compounds.

    Fluoride, of all inorganic substances, is among the least likely to be identified by a routine toxicological analysis. Acute poisonings with salts of hydrofluoric or fluorosilicic acid, however, although relatively uncommon, may occur. Some fluorosilicates, salts of fluorosilicic acid (e.g. Al, Zn, Pb, Mg) are used as stone consolidants, others

  • Skeletal Fluorosis: An Unusual Manifestation of Computer Cleaner Inhalant Abuse.

    Skeletal fluorosis is a metabolic bone disease caused by accumulation of fluoride and is generally associated with chronic exposure to fluoride-contaminated groundwater, a phenomenon endemic to developing countries. Whereas elevated water fluoride concentrations do not constitute a public health issue in the United States, emergence of skeletal fluorosis as a
