We have compared the renal excretion of fluoride in a variety of patients with chronic renal failure maintained with and without protein restriction before and during regular dialysis treatment and after transplantation. The patients tended to continue to excrete normal dietary loads of fluoride quite well until renal function was seriously reduced. From a regression of function on excretion th...
It was the aim of this study to investigate differences in fluoride bioavailability in different oral areas after the application of amine fluoride (AmF) and sodium fluoride (NaF). The null hypothesis suggested no differences in the fluoride bioavailability. The tongue coating was removed and biofilm samples from the palate, oral floor and cheeks were collected. All subjects brushed their teeth...
A passive dosimeter designed to measure exposure to hydrogen fluoride was tested under laboratory conditions over the concentration range of 0.56 – 4.47 mg HF/m. The lowest concentration was chosen to be close to the Polish TLV (0.5 mg HF/m). The dosimeter consists of a Whatman No.1 filter paper impregnated with K2HPO4 placed in a polyethylene holder protected by a polyethylene screen. After ex...
Methods: Twenty–one residential homes were surveyed. Three hundred and six healthy elders having at least 5 teeth with exposed sound root surfaces were randomly allocated into 1 of 4 groups: individualized oral hygiene instruction (OHI), OHI and applications of 1% chlorhexidine varnish every 3 months, OHI and applications of 5% sodium fluoride varnish every 3 months and OHI and annual applicati...
The first fluoride varnishes were developed during the 1960s (Duraphat) sodium fluoride varnish) and 1970s (Fluor Protector) silane fluoride varnish) to prolong the contact time between fluoride and enamel. Fluoride varnishes adhere to enamel, and calcium fluoride formed after application acts as a long-term reservoir of fluoride. Currently Duraphat varnish is the most widely used topical fluor...
OBJECTIVES To assess the fluoride concentration of different commercially available mouthrinses in central Saudi Arabia, and compare the obtained measurements with label values. METHODS This cross-sectional study identified 25 brands of mouthrinses in the markets of Riyadh city between August and September 2013. Nineteen brands of mouthrinses whose labels indicate the percentage of sodium fl...
PURPOSE To clinically evaluate and compare a dentifrice system in a dual-chambered tube, wherein one chamber contained sodium fluoride in a silica base and the other chamber contained dicalcium phosphate dihydrate (Test Dentifrice delivering 0.243% sodium fluoride), to a dentifrice containing 0.243% sodium fluoride in a silica base (Positive Control Dentifrice). MATERIALS AND METHODS This stu...
