Abstract
Aims: To compare 24-hour changes in quantitative light-induced fluorescence (QLF)-derived optical outcomes in artificially demineralized human enamel treated with glycerol-stabilized calcium phosphate (GCPC) or artificial saliva. Methods: Artificial enamel lesions were produced using a calcium/phosphate/fluoride-containing acetate-buffered demineralization solution (pH 4.7) for 72 hours. Forty-two enamel blocks were allocated to GCPC or artificial saliva (n=21 per group). QLF images were obtained at baseline (T0) and 24 hours (T24). Outcomes were maximum fluorescence loss (ΔFmax), integrated fluorescence loss (ΔQ), and software-mapped lesion area. ΔFmax was analyzed with t tests; ΔQ and lesion area were analyzed with nonparametric tests. Results: Mean ΔFmax change was +3.58±1.32% with GCPC and +0.67±1.52% with artificial saliva; the between-group mean difference was 2.91 percentage points (95% confidence interval, 2.02 to 3.80; Hedges g=2.01; p<0.001). Median ΔQ change was +624 px% (+97 to +14,399) versus +75 px% (-475 to +1,236; p=0.001), and median lesion-area change was -62 px² (-1,716 to -21) versus +27 px² (-373 to +959; p=0.014). Baseline lesion area differed between groups (p=0.011). Conclusion: GCPC produced greater 24-hour QLF-derived optical changes in ΔFmax and ΔQ than artificial saliva. Lesion-area change also differed, but baseline imbalance limits interpretation. Because QLF is an indirect optical method and no complementary mineral or structural validation was performed, the findings do not establish direct mineral gain or clinical effectiveness.
