Effects of Fluoride and Calcium Phosphate Materials on Remineralization of Mild and Severe White Spot Lesions

Figure 4

(a) DIAGNODent Pen readings of the mild lesions group before and after remineralization (mean ± sd; n = 10). Bars with dissimilar letters indicate values that are significantly different from each other. (P<0.05)

(b) DIAGNODent Pen readings of the severe lesions group before and after remineralization (mean ± sd; n = 10). Bars with dissimilar letters indicate values that are significantly different from each other. (P<0.05)
