Figure 12: SEM of a root canal treated with the SAF System. (a) Coronal part of the canal. (b) Middle part of the canal. (c) Apical part of the canal. All of these images are at 500× magnification. Canals were treated with the SAF system, with sodium hypochlorite and EDTA used as irrigants. All of the coronal and mid-root surfaces were clean of debris as well as of the smear layer. All of the apical parts of the canals were also free of debris, and in 65% of the cases, they were also free of the smear layer (Adapted from Metzger et al. 2010)[23]
