Abstract


Objectives: Dental caries and periodontal disease are infectious and chronic diseases. The aim of the study was to investigate the antimicrobial effect of mentha extracts against Streptococcus mutans (S. mutans) and Porphyromonas gingivalis (P. gingivalis).

Methods: This activity of mentha extracts were confirmed by the disk diffusion test and minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC) and colony forming unit (CFU) assays.

Results: S. mutans and P. gingivalis showed the highest antimicrobial activity within the inhibition zones. The antimicrobial activity was interrupted as the MIC and MBC of the herbal extracts against the two bacteria were 1 mg/ml and 10 mg/ml, respectively. The antimicrobial effect was determined by the CFU assay.

Conclusions: Mentha herb extract demonstrated potential antimicrobial activity against S. mutans and P. gingivalis that cause dental caries and periodontal disease.
