Introduction Fluoride (F−) is an important anion, present in various environmental, clinical and food samples. Small amounts of fluoride are vital for the human organism, but it is toxic in larger amounts. For adults the lethal dose is 0.20–0.35 g F− per kg body weight. Fluoride is widely used in various branches of industry and some fluoride compounds are formed as by-products in certain proce...

PURPOSE Systemic fluorides are effective in the prevention of dental caries but over ingestion can lead to dental fluorosis. Fluoride supplements may be under-prescribed for children residing in areas where drinking water is derived from wells, because of a lack of knowledge of dental providers or the effort required to test wells for fluoride before prescribing supplements. The purpose of this...

BACKGROUND To determine the severity of dental fluorosis in selected populations in Chiang Mai, Thailand with different exposures to fluoride and to explore possible risk indicators for dental fluorosis. METHODS Subjects were male and female lifetime residents aged 8-13 years. For each child the fluoride content of drinking and cooking water samples were assessed. Digital images were taken of...

The Present investigation covers the scientific comprehension of the potential effects of fluoride toxicity on body and testes weight and the spermatozoal activities in male albino rat and the beneficial effect of novel medicinal plant Tamarindus indica therapeutic treatment (10gm/kg body weight) after fluoride water intoxication. Three groups of male albino rats five of each were intoxicated w...

The range of fluoride levels in the drinking-water of cities and villages in South Africa was determined during the transition from a very dry (1983) to a wet (1984/85) period. The combination fluoride ion selective electrode was employed for the determination of the fluoride concentration. It was found that fluoride levels in drinking-water changed for 93% of the cities and villages studied du...

Fluoride concentrations in drinking water were analyzed relative to air temperature data collected in different provinces of Iran. Determining suitable concentrations of fluoride in drinking water is crucial for communities because of the health effects of fluoride on humans. This study analyzed fluoride concentrations in drinking water from selected Iranian provinces. The data were derived mai...

BACKGROUND Knowledge of fluoride levels in drinking water is of importance in dental public health, yet this information is lacking, at national level, in Nigeria. OBJECTIVE To map out fluoride levels in drinking water sources in Nigeria. MATERIALS AND METHODS Fluoride levels in drinking water sources from 109 randomly selected Local Government Areas (LGAs) in the 6 Nigerian geopolitical zo...

BACKGROUND Compared to the general United States (U.S.) population, Arizona counties along the U.S.-Mexico border have a higher prevalence of dental caries, which can be reduced with adequate fluoride exposure. Because of concern regarding local tap water quality, fluoride-free bottled water consumption is common in this region, raising concern that families are not receiving adequate fluoride ...

Fluoride is ingested primarily through consuming drinking water. When drinking water contains fluoride concentrations>0.7 parts per million (ppm), consuming such water can be toxic to the human body; this toxicity is called "fluorosis." Therefore, it is critical to determine the fluoride concentrations in drinking water. The objective of this study was to determine the fluoride concentration in...
