Purpose: The aim of this study was to examinate the antibacterial effect of mastic essential oil on a representative caries-inducing bacteria, Streptococcus mutans.
Methods: S. mutans UA159 was maintained in BHI medium containing 0.1% sugar at 37℃, 10% CO2. Strains were treated in nine different concentration of mastic essential oil (0, 0.05, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7%). After incubation for 16~18 hrs, antibacterial effect was evaluated by minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC), and disc diffusion method. Microtiter plate assay test was performed to analyze anti-adhesion ability of mastic essential oil on S. mutans.
Result: Mastic essential oil inhibited growth of S. mutans. The MIC and MBC on S. mutans were 0.2% and 0.4% concentrations of mastic essential oil, respectively. The inhibition zone in the disk diffusion analysis appeared from 0.4% mastic essential oil (14 mm), and the inhibition zone was increased dose-dependently. Mastic essential oil induced in anti-adhesive ability on S. mutans.
Conclusion: These results suggest that mastic essential oil may be used as a preventive measure against dental caries.
