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...

Drinking water contamination by fluoride is recognized as a major public health problem in many parts of the world. In fact, although fluoride is an essential trace element for animals and humans, excessive fluoride intake may cause adverse health effects. In this study we investigated the potential of a natural, high alumina content, bauxite for the removal of fluoride from contaminated water....

Abnormal fluoride levels in drinking water have been associated with adverse health effects. To determine the fluoride content of well waters in Enugu, southeastern Nigeria, water samples from 50 artisan wells chosen by multistage sampling procedure from the 5 zones of Enugu municipality were analyzed in duplicates for their fluoride content. The zonal mean values were 0.60, 0.70, 0.62, 0.62, a...

The purpose of this study was to assess exposure to drinking water fluoride and evaluate the risk of dental fluorosis among the Estonian population. The study covered all 15 counties in Estonia and 93.7% of population that has access to public water supplies. In Estonia groundwater is the main source for public water supply systems in most towns and rural settlements. The content of natural flu...

abstract aims: fluoride is one of the anions present in soil and water, and determining its level in drinking water is vital for preventing dental and bone diseases in societies. this research aimed to determine fluoride concentrations in drinking water sources of rural and urban areas of babol city, iran. instrument & methods: this descriptive cross-sectional study was conducted in babol city,...

Fluorosis is a dreaded condition caused due to high exposure of sodium fluoride in drinking water. The aim of this study was to use sensitive biomarkers to evaluate damage to adrenal gland after fluoride exposure. Recently, weaned Wistar rats were exposed to 100, 200 and 300 ppm fluoride concentrations in drinking water for a period of 20 and 40 days. At the end of exposure period, oxidative st...

besides human dental and skeletal fluorosis, drinking water above permissible levels of fluoride is known to cause a wide range of adverse health effects. in this study, the adsorption of fluoride from aqueous solution onto pretreated zeolite has been studied by using batch test. the large surface area of natural zeolite (i. e., clinoptilolite from miyaneh region, iran) was utilized to create a...

background: one of the most important health problems in life is dental caries or tooth decay. untreated caries are painful and may affect diet, school attendance, and sleep. tooth decay can also have significant negative health and social consequences in later life. objectives: the aim of this study was to determine the decayed, missing, filled teeth (dmft) index in 8-12 year old students in z...
