Online published on 13 December, 2018. Abstract Purpose The antiseptic property of root canal filling materials seems very important for the removal of residual pathogens from root canals. The aim of the current study was to investigate the antimicrobial activity of Mineral Trioxide Aggregate (MTA), Calcium Hydroxide (CH), Metapex, Zinc Oxide Eugenol (ZOE), and CEM-cement. Materials and Method Four standard bacterial strains including Staphylococcus aureus, Enterococcus faecalis, Pseudomonas aeruginosa, Bacillus subtilis and a type of fungus called Candida albicans were used. On five plates containing Brain Heart Infusion (BHI) agar, five cavities were made. Then, the plates were cultured by 0.1 ml of bacterial suspension with a concentration of 0.5 McFarland. Afterwards, the cavities were completely filled with the tested materials and were incubated at 37°C for 24, 48, and 72 hours. Diameters of microbial inhibition zones were then measured. Results The highest mean diameter of growth inhibition zones was observed around ZOE and then CH and CEM-cement. Conclusion CH was a viable alternative to ZOE.
