The study aimed to compare the remineralization capacity of toothpastes containing arginine by surface morphology evaluation and calcium and phosphate ions concentration assessment in enamel and dentine. Colgate Total, Colgate Sensitive ProRelief and Colgate Maximum Cavity Protection were selected for this study. Enamel and dentine samples were subjected to demineralization for 1 hour, three times a day, 14 days (group I, control). In groups II-IV the same demineralization cycles were applied, but the first and the last demineralization cycle was followed by the application of three toothpaste slurries for 3 minutes. In the conditions of this study, all the tested toothpastes provided remineralization of enamel and dentine after acid challenge. The toothpastes containing arginine leaded to higher remineralization when compared to the products that contains only fluoride.
Key words: arginine, fluoride, remineralization, enamel, dentine
