  		Figure. Illustration of the experiment. (a) Enamel blocks with known surface microhardness were fixed in acrylic holders, in contact with a test plaque prepared from S. mutans IB1600; each holder contained blocks from the same treatment, placed at each side of the appliance, in a split-mouth design. (b) After 30 min inside the mouth, 2 enamel blocks from each holder were removed, and the test plaque was collected for analysis of F, Ca, and Pi in "plaque fluid". (c) A one-minute rinse with sucrose solution was conducted, and 45 min after the rinse, the experiment was completed. (d) Test plaque from the remaining blocks was collected for fluid analysis. (e) We again determined surface microhardness on enamel blocks, to calculate the percentage of surface microhardness change (mineral loss).
