Brain, liver, kidney and muscles demonstrate significant changes in essential trace element (Cu, Zn, Mn and Fe) level in adult female mice given 30, 60 and 120 ppm sodium fluoride (NaF) in drinking water. These changes involve excess removal or accumulation of these trace elements in respective tissues. Changes observed were dose dependent and significant at 120 ppm NaF concentration in drinkin...

19 Membrane aerated biofilm reactors (MABRs) have potential in wastewater treatment as they 20 permit simultaneous COD minimisation, nitrification and denitrification. Here we report on 21 the application of the MABR to the removal of fluorinated xenobiotics from wastewater, 22 employing a Pseudomonas knackmussii monoculture to degrade the model compound 423 fluorobenzoate. Growth of biofilm in...

to investigate and compare the amount of fluoride release of conventional, resin modified and nanofilled resin modified glass ionomer cements.tablets of glass-ionomer cements were immersed in deionized water and incubated at 37°c. after 1, 2, 7, 15 and 30 days, fluoride ion was measured under normal atmospheric conditions by fluoride ion selective electrode. buffer (tisab ii) was used to decomp...

We performed batch dissolution experiments on different sized granite and biotite in pure water, in order to better understand the source and geochemical behavior of fluoride in groundwater. Very high concentrations of fluoride (up to 6–10 mg/l) were observed from granite leaching. Correlations between leached ions suggest that fluoride possibly originates from dissolution of biotite. After ~50...

background: fluoride is used increasingly in a variety of industries in india. emission of fluoride dust and fumes from the smelters of primary aluminum producing industries is dissipated in the work environment and poses occupational health hazards. objective: to study the prevalence of health complaints and its association with fluoride level in body fluids of smelter workers in a primary alu...

objectives: fluoride therapy is important for control and prevention of dental caries. laser irradiation can increase fluoride uptake especially when combined with topical fluoride application. the objective of this study was to compare the effects of co 2 and diode lasers on enamel fluoride uptake in primary teeth. materials and methods: forty human primary molars were randomly assigned to fou...

The beneficial effects of fluoride on human oral health are well studied. There are numerous studies demonstrating that a small amount of fluoride delivered to the oral cavity decreases the prevalence of dental decay and results in stronger teeth and bones. However, ingestion of fluoride more than the recommended limit leads to toxicity and adverse effects. In order to update our understanding ...
