WSL, white spot lesion. Frequencies and percentage of subjects affected by at least one new WSL, and teeth affected by new WSL or cavitations adjacent to bracket base area (scores 1, 3, 4) and (1; 4), and sub-bracket lesions or cavitations (score changes from 0 to 2; 3; 5; 6; or 7), separate for the distinctive tooth groups (upper anterior 12–22; 15–45; 16–46; 17–47).
