Abstract
Effects of interval and frequency of applying a new fluoride-containing enamel adhesive coating agent on remineralization were investigated. The coating agent containing 10ppm F was applied to the artificial white spots on the enamels of permanent bovine incisors at various intervals (1, 3, 7 and 14 days) and frequencies (0, 1, 2, 3, 4 and 5 times). The teeth were immersed in the calcifying solution (pH7.0) for 35 days at 37℃. The degree of remineralization of the white spots was evaluated by the solubility reducing effect in acetate buffer (pH4.0). Solubility reducing of the white spots increased with increases in the intervals between applying the coating agent, but was constant at intervals of more than 7 days. As to the frequency of coating, the white spots in which the coating agent was applied 1〜3 times were superior to untreated white spots with respect to reducing effects. These results suggest that the most suitable conditions of application with the coating agent are too coat 1〜3 times at an interval of more than 7 days.
