This study was designed to revalue topical fluoride treatment time and the time to refrain from rinsing, eating or drinking following a professional application.<BR>In order to investigate the application time, human enamel powder was given a topical fluoride application treatment with APF solution (pH 3.6, F<SUP>-</SUP>: 9, 000ppm) for 0, 1, 2, 3, 4, 6 and 8min. We compared fluoride uptake, Ca/P molar ratio and acid resistance test between all fluoride groups and the control.<BR>The fluoride concentrations in powder were similar in all groups of 3min or more, and were not statistically different in each group. After washing with 1 M KOH solution, fluoride concentration was decreased in all groups. Although in the 4min group some fluoride remained, all other fluoride groups proved not to be statistically different from each other in treatment time.<BR>In all groups, after treatment with fluoride, Ca/P molar ratio was increased significantly, suggesting the production of CaF2 in the enamel powder.<BR>The acid resistance test proved that release of calcium was inhibited in all fluoride groups both after treatment and after washing with 1 M KOH solution, though they showed a little difference depending on the demineralization time. All fluoride groups had the same or more acid resistance than the 4min group.<BR>To investigate the time for refraining from rinsing, eating or drinking, we measured the fluoride dissolved in water when the enamel powder treated for 4min with APF was immersed with or without stirring for 24h. When stirred, dissolved fluoride suddenly increased in all groups. We could not prove statistical difference in dissolved fluoride in the groups which were stirred directly after treatment, after 10, 20 and 30min.<BR>These findings suggested that the application time can be shortened to 4min and the time for refraining from rinsing, eating or drinking can be shortened to 30min.
