Figure 4. Scanning electron microscopy images of A, B, C, D, and E for A-type resin; A`, B`, C`, D` and E` for D type resin and A``, B``, C``, D`` and E`` for Q-type resin are Corega-tested surface, Polident-tested surface, Fittydent-tested surface, Control and Surface type, respectively. Bar is 10 μm. A- and Q-type resins showed more notched surface with deeply fissure (E and E``). A detailed analysis of the D (E`)-type resin surface displayed smooth and regular texture.
