DFT calculations were used to investigate adsorptionof  F-, Cl-, Li+ and Na+ ions on the exterior surface of Mg12O12 nanocage in the gas phase and water media. The most favorite position for adsorption of the studied anions and cations are atop of Mg and O atoms of Mg12O12, respectively. The strongest intera...

A new naked-eye chromogenic chemosensor based on 2-thiohydantoin shows high selectivity for fluoride ions and is used to develop a test paper for detection of fluoride ions in the solid state.

The effect of different sizes of structure directing agents on the ordering of the fluoride ions in pure silica MFI zeolites has been determined using magic angle spinning solid state NMR. By synthesizing fluoride containing pure silica MFI zeolites using methyltributylammonium cations as the structure directing agent, it has been possible to change the type of ordering seen for the fluoride io...

Fluoride ions play a critical role in preventing tooth decay. We investigated the microscopic effects of fluoride ions on hydroxyapatite (100) surface dissolution using in situ atomic force microscopy. In the presence of 10 mM NaF, individual surface step retraction velocities decreased by about a factor of 5 as compared to NaF-free conditions. Importantly, elongated hexagonal etch pits, which ...

We evaluated the concentration of fluoride release at the initial stage and after recharging the fluoride from a resin-based sealant containing surface reaction-type pre-reacted glass-ionomer (S-PRG) filler and conventional resin-based sealants. The concentration of other ions released from the sealants in the surrounding distilled water was also examined. At the initial stage, fluoride was rel...

The results of studies on the biological influence of magnetic fields are controversial and do not provide clear answers regarding their impact on cell functioning. Fluoride compounds are substances that influence free radical processes, which occur when the reactive forms of oxygen are present. It is not known whether static magnetic fields (SMF) cause any changes in fluoride assimilation or a...

UNLABELLED Regular supply of fluoride ions to the oral environment is one of the prophylactic actions against dental caries. Fluorides, whose exogenous action combines with saliva properties, condition the anticariogenic effect. Fluoride ions exhibit high chemical activity, can alter the oral environment parameters and inhibit the activity of enzymes. PURPOSE In the current study, the effect ...

THE caries inhibitory effect of fluoride is well documented (Brudevold et a], 1967; Horowitz and Heifetz, 1970). •As the initial site of the caries lesion Occurs on the surface of the tooth at the plaque/tooth interface, the fluoride con­ centration in the surface layers of enamel is important in combating the carious process (Isaac et al, 1958; Naylor, 1969). The fluoride in the enamel is deri...

Original research Assessment 0f Fluoride Ion Release from a Commercially Available Varnish Kumar S, Babu GLK, Subramaniam P Abstract: The remineralizing property of fluoride in a varnish depends on its sustained release, thus increasing the availability of fluoride ions around the tooth for a prolonged period. Aim: The purpose of this in vitro study was to assess the quantum of fluoride ions re...

The present work aims to study the level of fluoride in bore well, hand pump water samples of different villages of Mullana block, District Ambala, state Haryana & also to analyzed other water qualities parameters like pH, sulphate ions, chloride ions, total hardness, nitrite ions, methyl orange alkalinity, fluoride ion, iron, copper and cadmium. The analysis showed a minimum fluoride level of ...
