Table 5.

Median (minimum-maximum values) obtained in quantitative light-induced fluorescence (QLF) analysis at the first month compared to the baseline.

Type of varnish	ΔWS area (mm²)^a,b	ΔΔF (%)^b,c
TiF₄	0.01 (–9.15 to 1.19)	–1.29 (–16.30 to 4.74)
NaF	0.17 (–2.38 to 1.47)	–0.55 (–5.80 to 6.10)
Placebo	0.19 (–1.14 to 4.36)	–0.23 (–5.17 to 5.10)

^aΔWS: variation of the white spot lesion area. For ΔWS, negative values mean progression (demineralization), and positive values, regression (remineralization). The opposite is valid for ΔΔF.

^bKruskal-Wallis Test (p=.59 and p=.45, respectively).

^cΔΔF: variation of the mean fluorescence loss.
