We studied effect of fluoride mouthrinse on in vivo enamel solubility in four dental students. All 4 students rinsed for 30 seconds for 19 days with a 10 ml volume of a placebo solution (distilled water) every night (stage I). Then tion for 86 days (stage After that period, the fluoride group rinsed with a higher fluoride concentration solution (F: 1000 ppm) and the others continued the placebo solution for 54 days. in vivo enamel solubility was examined 4 times for the I stage, 5 times for the II stage and 4 times for the III stage by Nakagaki's method using 2μl of sodium acetate-hydrochoric acid buffer (1.4 M lactic acid, pH 2.3). The results were as follows. 1) in vivo enamel solubility was decreased by the fluoride mouth rinsing. 2) The difference in enamel solubility between stage I and stage II was greater than that between stage II and stage III.
