Figure 2: Scanning electron microscope photomicrograph of dentin surface prepared and irrigated with distilled water (control). Amorphous featureless smear layer obscuring the dentinal tubules. Few tubules appeared as depressions below surface (solid arrows). Grooves left by cutting can be seen (block arrows) (×1500)
