Enamel dissolution and fluoride uptake from sugar solutions. 1984

I Jerushalmi, and A Markitziu, and M Friedman, and I Gedalia

Solubility studies and fluoride uptake by enamel powder in xylitol-buffered solutions versus sucrose- and glucose-buffered solutions were carried out. The studies were done at a pH range of 4-8. The enamel solubility in the xylitol media was similar to the enamel solubility in the other sugar solutions--increasing with a decreasing pH. The solubility of enamel in the buffered sugar solutions was significantly lower as compared to the solubility in the sugar-free buffered solutions--up to the pH of 6. At the pH values of 7 and 8 the amounts of solubility were similar for the experimental and control solutions. No significant differences were found in the fluoride uptake by the enamel powder from the fluoride-containing sugar solutions at the pH values of 6 and 7.5 respectively. The results point to the conclusion that the xylitol does not differ from sucrose and glucose in its effect on enamel powder solubility and the uptake of fluoride ions by enamel.

UI MeSH Term Description Entries
D002241 Carbohydrates A class of organic compounds composed of carbon, hydrogen, and oxygen in a ratio of Cn(H2O)n. The largest class of organic compounds, including STARCH; GLYCOGEN; CELLULOSE; POLYSACCHARIDES; and simple MONOSACCHARIDES. Carbohydrate
D003743 Dental Enamel A hard thin translucent layer of calcified substance which envelops and protects the dentin of the crown of the tooth. It is the hardest substance in the body and is almost entirely composed of calcium salts. Under the microscope, it is composed of thin rods (enamel prisms) held together by cementing substance, and surrounded by an enamel sheath.
