Representative scanning electron microscopy images of root canal dentin in the root canal models after irrigation (×1,300 magnification): (a) G1 (CA/PUI + NaOCl/PUI), (b) G2 (18% EDTA + NaOCl/PUI), (c) G3 (NaOCl/PUI + 18% EDTA), (d) G4 (3% EDTA + 2.5% NaOCl/PUI), (e) G5 (NaOCl/PUI + 3% EDTA), and (f) G6 (no preparation and no irrigation).
