Background: To assess the antibacterial effect of ethanolic extract of propolis, mi-swak and green tea compared to sodium hypochlorite and chlorhexidine as root canal irrigants against E.faecalis biofilm using laboratory culturing and scanning electron microscope (SEM). Materials and Methods: fifty, human, single canalled teeth were used. The crown of each tooth was sectioned. After root canal preparation and sterili-zation, the roots were infected with E. faecalis. Roots inoculated with E.faecalis were incubated at 37Co for 7 days. Then root canals were instrumented using Revo S NiTi files and different irrigants: Sodium hypochlorite 3% (NaOCl), 2% chlorhexidine (CHX), 20% ethanolic extract of Egyptian propolis, 20% ethanolic extract of Miswak and 20% ethanolic extract of Green tea. Root canals were sampled before (S1) and immediate-ly after the chemo- mechanical preparation (S2). The data obtained collected, tabu-lated, and statistically analyzed. Results: NaOCl group (2.56±2.74) showed the lowest mean Log10 of bacterial counts, it was non-statistically significant different from CHX group (3.83±2.37), Propolis group (4.62±1.88) and Miswak group (4.93±2.01). NaOCl group showed statistically significantly lower mean Log10 of bacterial counts than Green tea group (5.82±0.16) and Saline group (6.39±0.30). Conclusion: Propolis, Salva-dora Perisca and green tea offer a promising natural antimicrobial alternative and may serve as a new endodontic irrigants.
