Abstract

The purpose of this study was to evaluate the antibacterial effect of root-end filling materials, MTA and amalgam, by agar diffusion test. Materials and methods: Blood agar plates were inoculated with bacteria Streptococcus mutans, Streptococcus mitis, Lactobacillus acidophilus, Staphylococcus aureus and Enterococcus faecalis each, and a polymicrobial suspension consisting of all the tested bacteria. Material samples were divided among the inoculated plates, and after 48 hours of incubation, the diameters of the inhibition zone (IZ) were recorded. Results: The strongest antibacterial effect of MTA was against Streptococcus mutans (IZ = 7.6 mm, sd 1.0), followed by Streptococcus mitis and Lactobacillus acidophilus (IZ = 7.3 mm, sd 0.5). The inhibition zone (IZ) for Enterococcus faecalis was 5.6 mm (sd 0.7), and for the polymicrobial suspension 5.3 mm (sd 1.0). Staphylococcus aureus was the only bacteria MTA did not show any antibacterial effect against. Amalgam showed no antibacterial effect against any of the bacteria tested. Conclusion: MTA showed antibacterial effect against 4 of 5 tested bacteria and the polymicrobial suspension, while amalgam did not inhibit the growth of any of the bacteria tested.
