Remineralization by fluoride enhanced with calcium and phosphate ingredients.

摘要: The effectiveness of fluoride ions provided by toothpastes and mouthrinses in promoting remineralization can be limited the low concentrations calcium phosphate saliva. purpose this study was to determine whether improved obtained from or that simultaneously deliver fluoride, calcium, dual-dispensing systems. Enamel specimens with artificial lesions between 60 90 microns deep were cycled 15 times through demineralization for 30 minutes, treated 5 minutes an experimental control toothpaste mouthrinse, remineralized minutes. In study, surface hardness increased 11.5 +/- 9.2 2.7 3.6 Vickers units, enamel content 5984 521 ppm 3971 531 toothpastes, respectively. Remineralization confirmed x-ray microradiography. mouthrinse 8.8 7.7 2.2 3.7 6111 1078 3160 364 mouthrinses, Use a non-fluoride led decrease 5.2 units despite 402 ppm. results demonstrate supplementation improve increase uptake.
