Representative scanning electron microscopy images of root canal dentin comparing root canal models: (a–c) and immersion models; (d–f) (×1,300 magnification); (a) G1 (root canal model: CA/PUI + NaOCl/PUI), (b) G2 (root canal model: 18% EDTA + NaOCl/PUI), (c) G3 (root canal model: NaOCl/PUI + 18% EDTA), (d) G7 (immersion model: CA/ultrasonic + NaOCl/ultrasonic), (e) G8 (immersion model: 18% EDTA + NaOCl/ultrasonic), and (f) G9 (immersion model: NaOCl/ultrasonic + 18% EDTA).
