Scanning electron micrographs of root canal dentin and the root filling materials Thermafil gutta-percha and AH Plus colonized with E.faecalis at magnification of 5000×. Treatments using 3% NaOCl or PDT severely reduce E. faecalis on dentin and the surfaces of the root canal filling materials. There were found few normal shaped bacterial cells on gutta-percha and AH Plus after treatments. Remaining cells on dentin after treatments showed abnormal shape.
