Fluorine is one of the most common elements in the Earth’s crust. Fluoride is recognized to be the most effective caries-preventive agent. The main sources of fluoride for people are generally food and drinking water. For this reason, the fluoride and also the metal ion (Ca, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, Pb and Zn) concentrations in the drinking waters collected from the city center of Kayseri...

normal 0 false false false en-us x-none ar-sa microsoftinternetexplorer4 background: to measure the amounts of fluoride released from fluoride-containing materials, four glass ionomer cements (fuji ix, fuji vii, fuji ix extra and fuji ii lc), a compomer (dyract extra) and a giomer (beautifil) were used in this study . methods: twenty cylindrical specimens were prepared from each material. the a...

Background; Fluoride is an essential nutrient for the human body. The major routes of fluoride intake include food and drinking water, though the absorption of fluoride from food is much easier. The aim of this study was to evaluate the amount of fluoride in the soil and tomato and onion crops on farms of Zanjan. Methods; Three farms of each crop (tomato and onion) were selected randomly. Ea...

Toothpastes should have a minimum concentration of 1000 ppm of fluoride (F) to control caries and also the active F agent must be chemically free (soluble) in the formulation. Thus, the aim of this study was to evaluate the concentration of soluble F in dentifrices used by 206 Brazilian children. The concentrations of total fluoride (TF), total soluble fluoride (TSF) and fluoride ion were deter...

fluoride is an essential element for human health. however, excess fluoride in drinking water may cause dental and/or skeletal fluorosis. drinking water is the main route of fluoride intake. the aim of the present study was to measure fluoride levels in human breast milk collected from two regions of golestan province, northern iran with different amount of fluoride concentration of drinking wa...

Information on the position of all five 5d levels of Ce in 17 different fluoride compounds has been collected. A model involving the polarizability of the fluoride ions, originally suggested by Morrison @J. Chem. Phys. 72, 1001 ~1980!#, is used to calculate the so-called spectroscopic polarizability asp from the observed average energy of the 5d configuration. It will be compared with actual in...

In this study, a newly developed S-PRG (surface pre-reacted glass-ionomer) filler-containing one-step adhesive, called SI (SI-IB551, Prototype), was evaluated regarding its fluoride release behavior. As a result, fluoride ion distribution in the tooth structures and acid resistance of cavity margins were also evaluated. In addition, Absolute (a fluoride-releasing one-step adhesive; AB) was eval...
