Background The main goal of an endodontic treatment is a complete debridement of the root canal system; however, currently mechanical shaping and chemical cleaning procedures for this purpose have deemed non-satisfactory. Methods The efficacy of peracetic acid (PAA; 0.5, 1.0, 2.0%), as a root canal irrigation solution, against  Enterococcus faecalis  (DSM 20478) and  Parvimonas micra  (DSM 20468) when compared with the one of sodium hypochlorite (NaOCI; 1.0, 3.0, 5.0%), chlorhexidine digluconate (CHX; 0.12, 0.2, 2.0%) and 0.9% NaCI (as a control solution) was in vitro investigated with the agar diffusion and direct contact methods. The inhibition zone diameters observed with the agar diffusion test were determined. The viable bacterial counts (CFU/ml) were calculated with the direct method. Results The agar diffusion test showed that all three root canal irrigation solutions had an efficacy against  E. faecalis  at all concentrations. The largest inhibition zone diameters against  E. faecalis  were observed with 5.0% NaOCI. At all three concentrations of PAA, NaOCI, and CHX, the inhibition zone diameter increased with increase in concentration. For  P. micra , PAA had a similar inhibition zone diameter despite a concentration increase. In contrast, for NaOCI and CHX, the inhibition zone diameter increased with increasing concentration. 2.0% CHX produced the largest inhibition zone diameter against  P. micra . For  E. faecalis , only the comparison between 2.0% PAA and 5.0% NaOCI showed statistical significance ( p  = 0.004). For  P. micra  the efficacy comparison between the lowest, middle, and highest concentrations of each solution, a statistical significance ( p  &lt; 0.05) was found for all three solutions. After direct contact with PAA, NaOCI and CHX, no viable bacteria could be determined for either  P. micra  or  E. faecalis . Conclusions PAA had a similar antibacterial efficacy as the one of NaOCl and CHX when in direct contact with  E. faecalis  and  P. micra . In the agar diffusion test, PAA showed a similar antibacterial efficacy as the one of CHX and a lower one as the one of NaOCl for  E. faecalis .
