Figure 2. Scanning electron micrographs of calcium-enriched mixture cement (left column) with (A) 0.1 mm, (C) 0.3 mm, and (E) 0.5 mm dentin thicknesses and mineral trioxide aggregate cement (right column) with (B) 0.1 mm, (D) 0.3 mm, and (F) 0.5 mm dentin thicknesses. White arrowheads indicate elongated cells and blue arrow heads show calcified nodules.
