The aim of this study was to determine the concentration of fluoride in urine of 1240 children (635 boys, 605 girls), aged 7-14, living in Gdańsk, Poland, and to examine whether a correlation exists between age and gender, school location, and fluoride level in the urine. Urinary F was determined with a fluoride ion specific electrode. The mean urinary F concentration in children attending two ...

Fluoride is found in all water resources at different concentrations and drinking water is the major source of fluoride exposure. Thus, because of the adverse effect of fluoride in low and high concentrations, the evaluation of its content in drinking water is necessary. In the present study, the temporal variations and spatial distribution of fluoride concentrations in the drinking water of vi...

Fluoride contamination in groundwater is one of the major environmental hazards in many districts of Rajasthan viz. Ajmer, Bhilwara, Nagaur, Tonk etc. Due to occurrence of fluoride in groundwater of central part of Rajasthan belt known as “Banka Patti”. This belt crosses the whole of Nagaur district.Groundwater quality with reference to fluoride content in the Jayal block located in the Nagaur ...

The in vitro fluoride uptake by dental enamel from two conventional acidulated phosphate fluoride gels was compared to a thixotropic acidulated phosphate fluoride gel. The fluoride concentration and enamel biopsy depths were determined using an acid-etch biopsy method based on calcium determinations. A significant fluoride uptake by dental enamel from a thixotropic topical fluoride agent follow...

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...

OBJECTIVE The aim of this study is to investigate urine fluoride concentration as a toxicity factor in a rural community in the state of San Luis Potosi, Mexico. MATERIALS AND METHODS A sample of 111 children exposed to high concentrations of fluoride in drinking water (4.13 mg/L) was evaluated. Fluoride exposure was determined by measuring urine fluoride concentration using the potentiometri...

Yes. brushing twice daily with topical fluoride toothpaste decreases the incidence of dental caries in infants and toddlers (strength of recommendation [Sor]: a, based on meta-analyses of randomized controlled trials [rCts]). High-concentration fluoride toothpaste delivers superior caries protection, but causes more dental fluorosis. use of high-concentration fluoride toothpaste should be targe...

Introduction: Over twenty developed and developing countries have regions with endemic floursis, on the other hand tooth decay as an infectious disease in human societies is reported to occur due to the shortage of fluoride in water. Since decayed, missing, and filled teeth DMFT is considered a 52 -character indicator in health equity, the present research aims at studying the relationship be...
