Mechanism of fluoride uptake by hydroxyapatite from acidic fluoride solutions. I. Theoretical considerations.
It is well established that fluoride plays an important role in the prevention of dental caries. Fluoridation of drinking water has been a successful public health measure in reducing the prevalence of tooth decay.' Beneficial results have also ensued from incorporation of stannous fluoride into a dentifrice.2 Wellock and Brudevold3 and others4,5 have reported a reduction in carious surfaces, a...
متن کاملFluoride Removal from Aqueous Solutions by NaOH-Modified Eucalyptus Leaves
Introduction: Fluoride (F) and its compounds are widely used in industries in which fluoride overdose leads to various detrimental diseases. In this study the effect of NaOH-modified Eucalyptus leaves on fluoride removal from aqueous solutions as a natural adsorbent was investigated. Materials and Methods: The focus of this study was on the effects of parameters such as pH (2-12), initial conc...
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 کاملFluoride release from fluoride varnishes under acidic conditions.
OBJECTIVE The aim was to investigate the in vitro fluoride release from fluoride varnishes under acidic conditions. STUDY DESIGN Poly(methyl methacrylate) blocks (Perspex, n=3 per group) were painted with 80 ± 5 mg fluoride varnish (n=10) and placed into artificial saliva for 30 min. Then, blocks were placed into either 1% citric acid (pH 2.27) or 0.3% citric acid (pH 3.75) solutions (n=3 per...
متن کاملDissolution rate of apatite powders in acidic fluoride solutions and the relationship to hydroxyapatite disk and bovine enamel behavior
The dissolution kinetics of synthetic hydroxyapatite (HAP) and carbonate-containing HAP powders have been studied in fluoride-containing acetate buffer solutions partially saturated with respect to HAP (K,, = 10-‘15 to IO-“‘). The experimental results indicate that in the ease of HAP powders the dissolution rates become veqr slow when the K,,, values of the dissolution medium are larger than 10...
