OBJECTIVE Considering that water is an importance source of fluoride intake, and that the consumption of mineral water and prevalence of dental fluorosis have been increasing, the aim of this study was to evaluate the consumption of mineral water and its fluoride concentration. METHODS The study was performed in residential districts of the municipality of Bauru, State of São Paulo, by means ...

BACKGROUND The published literature on the prevalence and severity of dental caries and dental fluorosis among school going children in Nalgonda district - An Endemic Fluoride belt was lacking . OBJECTIVES To assess the prevalence and severity of dental fluorosis and dental caries among 12 and 15 years old children in relation to fluoride concentration in drinking water . SETTINGS AND DESIG...

A biomarker for lifetime fluoride exposure would facilitate population-based research and policy making but currently does not exist. This study examined the suitability of primary tooth dentin as a biomarker by comparing dentin fluoride concentration and fluoride exposures. Ninety-nine children's exfoliated primary teeth were collected from 2 fluoridated and 2 fluoride-deficient communities in...

long-term exposure to high concentrations of fluoride is associated with several adverse effects on human including dental and skeletal fluorosis. we studied all the groundwater wells located in rural areas of khaf city, razavi province, northeastern iran between 2009 and 2010. fluoride concentration of water samples was measured by spadns method. we found that in rural areas the fluoride conce...

Incubation (30 degrees) of fat cell particulate fractions with fluoride before assay in the effective absence of fluoride results in activation of adenylate cyclase. Whereas the effect of fluoride (1.3 to 7 mM) when added to the assay was maximal in less than 2 min, 10 or 15 min of incubation before assay was usually required to produce maximal activation with any given concentration of fluorid...

Fluoride has been reported to be among natural pollutant of water in Africa. High fluoride levels beyond the recommended World Health Organization limit of 1.5 mg/l has been observed in various Africa countries. However, the information is scattered in different publication medium. Therefore, objective of this work was to put together the information on fluoride levels in surface and groundwate...

The influence of fluoride on tooth germ development, especially mineralised tissue, is well documented in numerous dental publications, but there are few reports concerning the influence of fluoride on enamel organ and dental papilla cells. The aim of the study was to assess histologically the development of tooth germs of 20-day-old rat foetuses whose mothers drank water without fluoride or wi...
