Table 1. The mean and standard deviation of the changes in the integrated fluorescence loss over lesions area (ΔQ) value for enamel adjacent to brackets bonded with different adhesive materials after 28 days of pH cycling in the two groups, with and without fluoride recharging.
Different letters (A, B, C) indicate a significant difference between values.
| Change in ΔQ (mm² %) | Fuji Ortho mean (SD) | Ketac Cem mean (SD) | Dyract mean (SD) | Transbond mean (SD) |
| Group 1 (no Fˉ- recharging) | -11.29A (10.88) | -8.99A (7.27) | -4.48A (3.13) | -82.85B (45.93) |
| Group 2 (Fˉ- recharging) | -6.74A (5.19) | -6.89A (4.84) | -4.44A (2.76) | -60.37C (25.00) |
