Figure 1. TEM photomicrographs of resin-dentin interfaces produced by Clearfil Mega Bond (Kuraray). The photomicrograph in (a) represents an unstained section and that in (b) a stained section of the control specimens that were not thermocycled. The image in (c) represents an unstained section and that in (d) a stained section of specimens that were exposed to 100,000 thermocycles. All sections are non-demineralized. B = bonding resin; H = hybrid layer; U = unaffected dentin.
