Fluoride 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...

متن کاملComparison 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 کاملtricalcium phosphate containing sodium hexametaphosphate as polymer suspension stabilizer
tricalcium phosphate as hydroxyapatite is used as a suspension stabilizer in styrene polymerization process. particle size of tcp plays an essential role in the particles’ size distribution and geometrical form of polystyrene products. as the particle size of tcp is reduced, there will be much better chance to engulf the styrene particles. the higher the number of tcp particles surrounding each...
متن کاملAcidification of blood is superior to sodium fluoride alone as an inhibitor of glycolysis.
BACKGROUND Sodium fluoride is the preferred agent to inhibit glycolysis. Its action is not immediate, however, and complete inhibition is delayed for up to 4 hours. A more effective method is needed. Acidification of blood combined with the addition of NaF and EDTA appears to be such a method. We studied whether acidification was indeed more effective than NaF. METHODS We conducted 6 independ...
