Fig. 2From: Aesthetic impact of resin infiltration and its mechanical effect on ceramic bonding for white spot lesionsThe effect of resin infiltration on the adhesive properties of WSLs. (A) The shear bonding strength of the Ctrl group, Bo group, and R-Bo group (n = 10). (B) Failure pattern analysis of the Ctrl group, D group, and DR group (n = 10). (C) The microleakage depth of the Ctrl group, Bo group, and R-Bo group (n = 15). (D) Representative SEM images of the Ctrl group, D group, and DR group (2000×, scale bar = 20 μm; 5000×, scale bar = 10 μm). The B zone: bonding agent; the E zone: enamel. *P < 0.01, **P < 0.001Back to article page
