Abstract | ||||
Aim : The aim of the present study was to evaluate the antimicrobial activity of four irrigating solutions against Enterococcus faecalis compared with sodium hypochlorite 5.25% namely: propolis extract, QMix, Chloroxylenol and CHX-Plus Materials and methods: Enterococcus faecalis (batch no. 10541) thawed and incubated under aerobic condition. The harvested bacterial colonies are then spectrophotometrically calibrated to 5.9 x 104 (CFU/mL-1). Fifty specimens instrumented conventionally, reaching master apical file size #50. Twenty μL of the bacterial culture transferred to the canal lumen using sterile micropipette. All specimens were then incubated for 48 hours at 37 ˚C. 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 of significant reduction of bacteria. Although QMix, NaOCl and chlorhexidine plus are capable of reducing bacterial count their effect is statistically insignificant | ||||
