Table 1. Median (minimum-maximum) of the dentin erosive loss for different groups.

Solutions	Median (min; max)
Erosion Protection^®(positive control)	0.86 (0.67; 1.85)^bc
TiF₄ (0.0815%)	-0.19 (-0.45; -0.05)^a*
NaF (0.105%)	1.56 (1.01; 2.38)^cd
NaF+TiF₄ (0.042%+0.049%)	0.75 (0.21; 1.59)^ab
NaF+TiF₄ (0.063%+0.036%)	1.08 (0.59; 1.66)^bc
Negative control	1.80 (1.23; 4.94)^d

* Negative value means increase of the surface (deposition)

Different letters show significant differences among the groups; min=minimum; max=maximum (p<0.0001)
