OBJECTIVES The purpose of this study was to investigate the relationships between caries experience and dental fluorosis at different fluoride concentrations in drinking water. The impact of other fluoride products also was assessed. METHODS This study used data from the 1986-87 National Survey of US School-children. Fluoride levels of school water were used as an indicator of the children's ...

BACKGROUND There are concerns that altered thyroid functioning could be the result of ingesting too much fluoride. Community water fluoridation (CWF) is an important source of fluoride exposure. Our objectives were to examine the association between fluoride exposure and (1) diagnosis of a thyroid condition and (2) indicators of thyroid functioning among a national population-based sample of Ca...

In Northern Thailand, incidences of fluorosis resulting from the consumption of high-fluoride drinking-water have been documented. In this study, we mapped the high-fluoride endemic areas and described the relevant transport processes of fluoride in enriched waters in the provinces of Chiang Mai and Lamphun. Over one thousand surface and sub-surface water samples including a total of 995 collec...

The prevalence of fluorosis is mainly due to the consumption of more fluoride through drinking water. It is necessary to find out the fluoride endemic areas to adopt remedial measures to the people on the risk of fluorosis. The objectives of this study are to estimate the fluoride exposure through drinking water from people of different age group and to elucidate the fluoride endemic areas thro...

The introduction of fluoride to drinking water in 1958 resulted in a dramatic reduction of dental caries [1]. Subsequently, fluoride supplements were advocated for children whose water was not fluoridated, and now almost all toothpaste contains fluoride. The result is that multiple sources of fluoride, such as fluoridated toothpastes, fluoride supplements (drops and lozenges) and naturally occu...

AIM To estimate the prevalence of dental fluorosis in relation with different fluoride levels in drinking water among school going children of 6-12 years age group. MATERIALS AND METHODS Dental fluorosis was recorded using Dean's index in school children of selected villages. The drinking water samples of all the selected villages were collected in polyethylene bottles and the fluoride conten...

Sir, Ludlow et al. [1] only confirmed that our knowledge of the potential adverse effects of chronic low fluoride supplementation of drinking water on normal or diseased kidneys is insufficient. More than 60 years after water fluoridation, there is no high-level evidence as most published studies are small, have methological deficiencies or are otherwise flawed. There are two areas of concern r...
