Figure 7: Atomic force microscopy images of a representative sample from Group 2A (37% phosphoric acid etchant at 7 s). (a) 20 μm × 20 μm surface area of the etched primary dentin showing depth of -2.5μm and height of 1.8 μm from the surface. (b-d) Image of the sample along the X, Y and Z axes respectively showing the near complete removal of smear layer, opening of dentinal tubules with exposed odontoblastic process Image of the sample along the X,Y and Z axes respectively showing the near complete removal of smear layer, opening of dentinal tubules with exposed odontoblastic process and irregular surface of the intertubular dentin suggestive of increased surface roughness
