BACKGROUND The prevalence of root caries is increasing with greater life expectancy and number of retained teeth. Therefore, new preventive strategies should be developed to reduce the prevalence of root caries. The aim of this study was to investigate the effects of fluoridated milk on the remineralization of root dentin and to compare these effects to those of sodium fluoride (NaF) applicatio...

OBJECTIVES The aim of this in vitro study was to compare the remineralizing effect of three rinses: (A) 0.17% sodium monofluorophosphate and 0.05% calcium glycerophosphate (220 ppm fluoride), (B) 0.05% sodium fluoride (220 ppm fluoride) and (C) control mouthrinse (without fluoride or calcium). METHOD AND MATERIALS Demineralized areas were created in 90 pieces of bovine enamel by submerging th...

According to SCHOUR and SMITH (1934), in ground sections viewed microscopically with transmitted light, enamel and dentin showed light (disturbed) and dark (recovery) incremental layers for each injection of sodium fluoride. IRVING (1943) injected fluoride in different doses in an attempt to estimate its effect on the basis of the amount per kilogram of body weight of the animal. Both hypocalci...

OBJECTIVES This study evaluated the effect of incorporating increasing concentrations of sodium fluoride in incubation media, on the loss of dry mass and solubilization of collagen from demineralized dentin beams incubated for up to 7 days. The effect of fluoride on the inhibition of matrix-bound metalloproteinases (MMPs) was also measured. METHODS Dentin beams were completely demineralized i...

We present an efficient fully automated sodium [18F]fluoride radiosynthesis on a new iMiDEV™ cassette-based microfluidic platform.

This paper reports the inhibition kinetics of mushroom (Agaricus bisporus; J.E. Lange) polyphenol oxidase (PPO) with benzoic acid, sodium azide and sodium fluoride as inhibitors, and pyrocatechol as substrate. Mushroom PPO was significantly inhibited by all of the tested inhibitors. Diphenolase activity of mushroom PPO exhibited the competitive-type inhibition with benzoic acid as an inhibitor;...

The number of tooth whitening products available to patients has grown dramatically during recent years. While peroxide is the primary agent found in products that bleach and remove intrinsic sources of discoloration, various ingredients are incorporated in formulations to remove and inhibit extrinsic sources of tooth discoloration, ie, tooth stain. Recently, an advanced antitartar ingredient w...

1. Using male rats, the availability of fluoride from five by products of the aluminium smelting industry was tested. This was done by considering the balance between fluoride administered in controlled diets and the total fluoride content of waste products eliminated over an experimental period of 1 week. 2. Results indicated that yields of available fluoride expressed as percentage weight of ...

Several properties of the fluoride ion at physiological concentrations are known which may be concerned with its actions in reducing dental caries. T h e properties that have been most thoroughly studied as a basis of the anticaries action are: (I) the incorporation of fluoride in the hydroxyapatite of the calcified tissues, both during and after their formation, thus increasing the proportion ...

Excessive fluoride intoxication plays an important role in the development of dental, skeletal and non-skeletal fluorosis. The aim of this study was to ascertain the toxic effect of excessive fluoride ingestion on the level of hydroxyproline and expression of type 1 collagen gene in rat bone and its amelioration by supplementation with Tamarindus indica fruit pulp extract. Forty albino rats wer...
