Aim : The aim of the present study was to evaluate the antimicrobial activity of four irrigating solutions against Enterococcus faecalis compared with sodium hypochloride 5.25% namely: propolis extract, QMix, Chloroxylenol and CHX-Plus.Results : Intracanal sample collection by paper points showed an insignificant difference between different irrigation solutions tested and positive control group at p=0.001. group 1 showed a median of 8.9*104(CFU/ml), where group 2, 3, 4 and positive control groups showed mean values of 2.2*10⁴, 7.3*10⁴, 8*10⁴ and 3*10⁴ (CFU/ml) respectively. Negative control group showed the highest significant values for colony forming units (118.⁴*10⁴CFU/ml).Conclusion : All groups except the saline produce significant reduction of bacteria. Although QMix, NaOCl and chlorhexidine plus are capable of reducing bacterial count their effect is statistically insignificant.
