Comparison of Fluoride Uptake into Enamel from Sodium Fluoride Gel 0.05% Produced in Iran and Stannous Fluoride 0.4% Gel
Background & Aims: The present study compared fluoride uptake into enamel from sodium fluoride 0.05% gel and American Dental Association approved fluoride gel (Stannous fluoride 0.4% , Sultan Co.) when used on healthy enamel of the intact teeth. Methods: In an experimental study, 30 intact teeth extracted for orthodontic purposes were randomly assigned into two groups of 15 teeth. The teeth wer...
متن کاملIonic Conductivity Measurements of Barium Fluoride Single Crystals
We have measured the a. c. conductivity of pure BaFz single crystals up to 1 336 K. At the higher temperatures we observed polarisation effects possibly due to a reaction of the crystal with the atmosphere in the cell. The defect energies derived from the low temperature region agree well with those obtained by Barsis and Taylor [27, 281. The effect of the high temperature phase transition on t...
متن کاملRadiofluorination using aluminum-fluoride (Al18F)
Targeted agents are increasingly used for treating cancer and other diseases, but patients may need to be carefully selected to maximize the potential for therapeutic benefit. One way to select patients is to bind an imaging radionuclide to a targeting agent of interest, so that its uptake in specific sites of disease can be visualized by positron-emission tomography (PET) or single-photon emis...
متن کاملOn optical bleaching of barium fluoride crystals
Barium fluoride (Baf2) crystals were considered by the GEM Collaboration, to be used in constructing a precision electromagnetic calorimeter at the SSC [1] . The key issue of using this crystal at the SSC is its radiation resistance [2] . An Expert Panel was assigned by the SSC laboratory to review the radiation damage problem of BaFz. The Panel met in December 1991 and again in January 1992 fo...
متن کاملFluoride release from three glass ionomers after exposure to sodium fluoride and acidulated phosphate fluoride gels
BACKGROUND Glass ionomer (GI) restorations exposed to fluoride have the ability to slowly release fluoride. Therefore, the aim of this study was to investigate fluoride release from three GIs before and after exposure to sodium fluoride (NaF) and acidulated phosphate fluoride (APF). MATERIALS AND METHODS Fifteen disc-shaped samples (6 mm in diameter and 2 mm in thickness) from three GIs (Fuji...
