The 12-week had significantly larger areas of demineralization than the 6-week (P=0.041) and 4-week (P=0.001) groups. Changes in impact was significantly (P=0.007) greater in the 12-week group than 4-week group, but not greater than the 6-week group. There were no statistically significant differences between 4- and 6-week groups in the
