teeth
At baseline, 17 patients (21.0%) in the FMR group showed 0 DL, while 22 patients (25.9%) in the HFT group and 15 (18.3%) patients in the control group showed 0 DL. There was no statistically significant difference between the groups regarding baseline DL status on patient level (Relative risks (risk ratios) for increase in ≥1, ≥2, and ≥3 demineralized lesion (DL) in all teeth and in the aesthetic zone, pairwise comparisons with 95% CI.
