Enamel solubility reduction by acidulated phosphate-fluoride (APF) treatment

Community Dentistry and Oral Epidemiology, 1978
abstract The enamel solubility reducing (ESR) potential of acidulated phosphate‐fluoride (APF) solutions containing varying amounts of F was studied. Commercial APF (1.23% F, pH 3.0) reduced solubility by about 80%. Fivefold dilutions of this APF were made with either phosphoric acid or water without significant effect on ESR potential.

Fluoride Acquisition in Vitro by Etched Enamel from Acidulated Phosphate-Fluoride Preparations

Journal of Dental Research, 1973
Fluoride uptake by acid-etched human enamel from acidulated phosphate-fluoride solutions was determined and compared with previous findings with sound enamel. Etched enamel acquired about five times more fluoride than sound enamel. The relative efficacy of different fluoride solutions was not always the same with etched and sound enamel.

The clinical cariostatic effectiveness of two concentrations of acidulated phosphate-fluoride mouthwash

Journal of the American Dental Association, 1975
Two acidulated phosphate-fluoride mouthwashes that contained either 100 or 200 ppm of fluoride ion were compared with a placebo mouthwash to determine their anticariogenic effectiveness. The twice-daily use of an acidulated phosphate-fluoride mouthwash that contains a small amount of fluoride is effective in reducing the incidence of dental caries in ...

Influence of acidulated phosphate fluoride solution on the color stability of indirect composites

Journal of Prosthetic Dentistry, 2004
Although acidulated phosphate fluoride (APF) agents are known to be useful for caries-preventive interventions, few studies have examined the influence of APF agents on indirect composite materials.This study examined whether exposure to APF agents affects color stability when a composite is exposed to a common staining agent.Forty light-polymerized ...

Surface roughness and gloss of indirect composites etched with acidulated phosphate fluoride solution

Acta Odontologica Scandinavica, 2009
To evaluate the surface characteristics of indirect composites etched with acidulated phosphate fluoride (APF) solution. MATERIAL AND METHODS. APF solution was applied to specimens of six composite materials. The surface morphological change was measured with a confocal laser scanning microscope. Gloss measurement and scanning electron microscope (SEM)

The Effect on Dental Caries of Weekly Rinsing with a Neutral Sodium Fluoride or an Acidulated Phosphate-Fluoride Mouthwash

Journal of the American Dental Association, 1973
Three groups of schoolchildren in Portland, Ore, rinsed weekly with a placebo mouthwash, a neutral sodium fluoride rinse containing 0.3% fluoride, or an acidulated phosphate-fluoride rinse containing 0.3% fluoride. After two years, the children who had rinsed with the fluoride mouthwashes had lower incremental caries scores than did the control ...

Comparison of In Vitro Fluoride Uptake by Human and Bovine Enamel from Acidulated Phosphate-Fluoride Solutions

Journal of Dental Research, 1974
Sound human enamel and bovine enamel were treated with various acidulated phosphate-fluoride solutions. Fluoride uptake by human and bovine enamel was different for many of the solutions. This difference demonstrates that bovine enamel may not be an adequate substitute for human enamel in fluoride uptake studies.

Reaction of Acidulated Phosphate-Fluoride Solutions with Human Apatite

Journal of Dental Research, 1973
Finely pulverized human enamel was reacted with acidulated phosphate-fluoride solutions. The products were analyzed for fluoride content and examined by X-ray difjraction and infrared absorption. Fluoride content of the products and the amount of calcium fluoride formed increased with increasing reaction time, temperature, or both.

In vitro evaluation of an acidulated phosphate fluoride prophylaxis paste

Archives of Oral Biology, 1968
Abstract Acidulated phosphate sodium fluoride, acidulated phosphate silicofluoride and stannous fluoride solutions were tested for fluoride and pH compatibility with a number of abrasives. Silicon dioxide was found to be compatible when used with the acidulated phosphate silicofluoride solution.

Clinical study of an amine fluoride gel and acidulated phosphate fluoride gel

Community Dentistry and Oral Epidemiology, 1976
Abstract This study compared caries inhibition in children by an amine fluoride and an acidulated phosphate fluoride when administered in a topically applied gel. In addition, the effects of applying amine fluoride daily and weekly were compared. Four hundred and sixty‐eight children, ages 6 to 13, were randomly assigned to one of five treatment groups
