Figure 2

Representative images from visualization of cut sections of sheared dentinal surfaces by SEM: (a) group 1: control group, no filling material, no solvent; (b) group 2: Metapex; (c) group 3: Metapex+ethanol solvent; (d) group 4: ZOE; (e) group 5: ZOE+ethanol solvent; (f) group 6: ZOE+orange oil solvent. Arrows show the gap between the dentin and composite resin.
