Figure 4:

The effects of long-term incubation in esterase-containing media on the fracture mode of composite-adhesive-dentin bonded specimens, adapted from data first provided by Serkies et al. and Shokati et al. [43, 46]. Note the movement of the fracture plane (red line) over 180 days through the hybrid layer (HL) and adhesive, with different exposure of resin tags within dentinal tubules (T). Representative SEM micrographs are provided.
