We have measured the number of fluoride ions bound to one molecule of succinate dehydrogenase (SDH) of submitochondrial particles from porcine kidney cortex. Enzyme activity was studied according to the method of Dixon and the number of fluoride ions bound was established arithmetically. A mixed competitive and noncompetitive inhibition of SDH by fluoride was confirmed. At high levels of succin...

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...

in this research calcium fluoride nanoparticles and its different amount of cerium ion dopant (5%and 10%) were prepared. the mentioned nanoparticle were studied by fourier transform infrared spectroscopy (ftir) , x-ray diffraction (xrd), absorption and photoluminescence spectra (pl) and scanning electron microscopy (sem). the xrd patterns indicate a typical cubic fluorite structure and no other...

n this study, the fluoride concentration and pH of 14 commercial brands of mouthrinses were assessed in order to compare them with the values expressed on the labels and with those established by the National Sanitary Surveillance Agency. Forty-two (42) products were obtained from three places, with different manufacturing batches. The fluoride concentration was determined in diluted solutions,...

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 in aquatic systems is increasing due to anthropogenic pollution, but little is known about how this fluoride affects organisms that live in and around aquatic habitats. Fluoride can bioaccumulate in structures comprised of calcium carbonate, such as shells and skeletons of both freshwater and saltwater species as diverse as snails, corals, and coccolithophorid algae. In this article, i...

Fluoride is recognized as an effective agent for dental caries prevention. Generally, the main source of fluoride intake is drinking water. In this study, fluoride content in 18 commercial brands of bottled waters was investigated. Six samples from each batch of 18 Iranian commercial brands of bottled waters were supplied. The fluoride content of samples was analyzed by Fluoride Ion Selective E...
