SEM micrographs of root canal walls and dentinal tubules. Control group: (a) E. faecalis biofilms on dentinal walls. Conventional regimen: (b) scattered E. faecalis in the root canal wall and dentin tubules entrance. Alternating regimen: (c) scarce E. faecalis in entrance dentin tubules. Magnifications: (a) 5000X, (b) 7200X, and (c) 10.000X.
