(a) Representative images of root dentin at × 2 K magnification after the different irrigation protocols on the surface. The letters on the images indicate the areas that were viewed at higher magnification and are shown in (b). (b) High magnification scanning electron micrographs (3 K ×: A,C,E; 4 K ×: B,D); of the areas marked by the letters A–E in Figure (a). The areas are indicated with white arrows. (A,B) shows the presence of cuboid crystals rich in sodium and chlorine on dentin and inside dentinal tubules, respectively; (C) shows the peritubular and intertubular dentinal erosion; (D) shows the presence of smear layer inside dentinal tubules and (E) shows the sclerosis of dentinal tubules.
