We describe a pretreatment method before determining the total fluoride in solutions containing tetrafluoroborate ion (BF(4)(-)) with ion-selective electrodes (ISEs). BF(4)(-) was quantitatively converted to free fluoride by reacting with aluminum ions. The total fluoride concentration was then determined by ISE analysis without preliminary steam distillation using a tartrate- and tris(hydroxym...

fluoride in drinking water has a profound effect on teeth. since drinking water is an important source of fluoride, the evaluation of the fluoride content of water resources is necessary. temporal variations and spatial distribution of fluoride in drinking water of some selected parts of kurdistan province, iran, have been studied using geographic information system (gis) techniques. thus, 40 v...

Carney, Shirley A., Hall, M., Lawrence, J. C., and Ricketts, C. R. (1974). British Journal of Industrial Medicine, 31, 317-321. Rationale of the treatment of hydrofluoric acid burns. On contact with skin hydrofluoric acid yields hydrogen and fluoride ions, which exhaust the tissue's buffering capacity. Fluoride was found to be toxic to skin cells, as judged by the accumulation of 3-phosphoglyce...

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...

In some part of the world, groundwater source can become unsafe for drinking due to the high concentration of fluoride ions [1]. The low cost and facile-produced adsorbent like palm stone could effectively removed fluoride ions through adsorption process. In this dataset, the influence of fluoride ion concentration, solution pH, adsorbent dosage, and contact time on fluoride ion adsorption by p...

statement of problem: the casein phospho peptide-amorphous calcium phosphate with or without fluoride (cpp-acpf and cpp-acp respectively) are of considerably new materials which are highly recommended for prevention of dental caries. however, there is a shortage in literature on how they affect the ion concentration of saliva or dental plaque. objectives: the aim of this study was to evaluate t...

Journal American Dental Association; 127: 895-901, 1996. Kiritsy, MC et al. Assessing fluoride concentrations of juices and juice-flavored drinks. In this study, the authors analyzed 532 juices and juice drinks for fluoride. Fluoride ion concentration ranged from 0.02 to 2.80 parts per million. Children’s ingestion of fluoride from juices and juice-flavored drinks can be substantial and a facto...
