ABSTRACT

Although fluoride was once considered an essential nutrient, the U.S. National Research Council has since removed this designation due to the lack of studies showing it is essential for human growth, though still considering fluoride a "beneficial element" due to its positive impact on oral health. The U.S. specifies the optimal level of fluoride to range from 0.7 to 1.2 mg/L (milligrams per liter, equivalent to parts per million), depending on the average maximum daily air temperature; the optimal level is lower in warmer climates, where people drink more water, and is higher in cooler climates. High concentrations of fluoride (F–) in drinking water are harmful to human health. This communication reports F– incidence in ground water and its relation with the prevalence of dental and skeletal fluorosis in Ambikapur Block, Sarguja District, and Chhattisgarh, India. In 1994 a World Health Organization (WHO) expert committee on fluoride use stated that 1.0 mg/L should be an absolute upper bound, even in cold climates, and that 0.5 mg/L may be an appropriate lower limit. A Australian systematic review recommended a range from 0.6 to 1.1 mg/L Assay of fluoride concentration in ground water samples around Ambikapur district in Sarguja revealed that fluoride content in beyond the permissible limit in a some residential areas. The extent of Fluoride present in different samples was obtained by spectrophotometer. the extent of fluoride was found in village Badadamali found to be from minimum 2.0 to 3.0 mg/l. village Khirbar found to be from minimum 2.1 to 3.0 mg/l. but in village Mudesha and Nandamali found to be from minimum 2.1 to 3.50 mg/l. it is further added that extent of fluoride content in water depends on the climatic conditions and increase in summer.
