Number of viable Enterococcus faecalis after contact with the primer. (A, B) Planktonic bacteria and (C, D) adherent bacteria. Contact times: 30 sec (A, C), 60 sec (B, D). (E, F) Infected root model. (F) Treatment with 5% NaOCl alone or 5% NaOCl + EP. *No bacteria were recovered. The bar represents the standard deviation of 3 replicates. No significant differences between the same letters (i.e., a-d; analysis of variance and Student-Newman-Keuls’s test; p < .05). CP, control primer; EP, experimental primer; PP, proprietary primer.
