Mineralization of Dentinal Lesions with Different Concentrations of Fluoride

Table 2

Lesion depth before remineralization (BR) and after remineralization (AR) in each group (mean ± SD) as observed with the polarized light microscope.

	F level (ppm)	Time (days)	Lesion depth (µm)
BR	≈0.0	14	210 ± 10
AR	0.0	7; 14	195 ± 10; 200 ± 15
	0.1	7; 14	165 ± 20; 168 ± 20
	0.5	7; 14	170 ± 10; 165 ± 15
	1.0	7; 14	169 ± 15; 167 ± 15
	5.0	7; 14	165 ± 10; 163 ± 20
	10.0	7; 14	170 ± 30; 169 ± 20
