Fluoride and arsenic are two common inorganic contaminants in drinking water that are associated with impairment in child development and retarded intelligence. The present study was conducted to explore the effects on spatial learning, memory, glutamate levels, and group I metabotropic glutamate receptors (mGluRs) expression in the hippocampus and cortex after subchronic exposure to fluoride, ...

The study was undertaken to determine serum/urinary fluoride status and comparison of free T4, free T3 and thyroid stimulating hormone levels of 8 to 15 years old children with and without dental fluorosis living in an endemic and non-endemic fluorosis area. A sample group of 60 male and female school children, with or without dental fluorosis, consuming fluoride-contaminated water in endemic f...

The objectives of this study were to measure dietary fluoride intake in children aged 3-7 years, to correlate dietary fluoride and fluoride content in water for used in schools and to estimate fluoride gained from the daily diet. Fifty food samples were collected in 45 schools under the jurisdietion of the Border Patrol Police Department. The schools were sampled by multiple stratified cluster ...

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...

Water samples from 110 public wells in Ohio were analyzed for fluoride content using both an ion-specific electrode and a coIorimeter. In addition to the fluoride testing, analyses were performed on selected known interfering substances in the water. Sixty per cent of the samples differed by > 0.1 ppm fluoride with a mean difference of+ O. 14 ppm. Prescriptions for dietary fluoride supplementat...

of human plasma fluoride concentration. rg6o.-There is a constancy of plasma fluoride content of individuals who use communal water within the range O. 15-2.5 ppm fluoride. With an intake of 5.4 ppm of fluoride in the communal water there is a slight but significant elevation of the plasma concentration. There is no evidence of a marked or prolonged rise of plasma fluoride content following the...

Fluorides are found in the waste discharges from process streams in a number of industries. Significant amounts of fluoride come from the following industries: semiconductor, photovoltaic, glass manufacturers, electroplating, steel and aluminum, pesticides and fertilizer. The fluoride concentration in untreated effluent can vary over a large range, and the allowable level for discharge depends ...

Seven hundred eight patients aged 5-19 years in a pediatric practice in North Carolina were selected using a random-start, systematic sampling procedure and enrolled in a case control study to determine risks for fluorosis. Subjects were examined by four trained examiners using the Tooth Surface Index of Fluorosis (TSIF). Information on fluoride exposures and other explanatory variables was obt...

Introduction Many studies have shown that fluoride can cross the placenta and that exposure to high fluoride during pregnancy may result in premature birth and/or a low birth weight. Lamphun is one of six provinces in Thailand where natural water fluoride (WF) concentrations >10.0 mg/L were found, and it was also found that >50% of households used water with high fluoride levels. Nevertheless, ...
