RESUMO
Background: People globally are turning to herbal products to reconnect with nature. Cost efficacy and minimal side effects are the reasons for this changeover. This study assessed the effect of Amorphophallus paeoniifolius as an antimicrobial agent against Porphyromonas gingivalis, Prevotella intermedia, and Fusobacterium nucleatum. Aim: To determine and compare the antimicrobial activity of aqueous and ethanolic extracts of A. paeoniifolius on periodontal pathogens. Materials and Methods: Aqueous and ethanolic extracts of A. paeoniifolius were tested against the standard strains of the selected bacteria. Minimum inhibitory concentrations (MIC) and minimum bactericidal concentration (MBC) were used. These tests assessed the lowest concentrations of test agent, either by showing a lack of turbidity or by no or few bacterial growth colonies, respectively. In this study, tetracycline hydrochloride was used as the control group. Results: Aqueous and ethanolic extracts of A. paeoniifolius showed antibacterial activity at various concentrations against the selected organisms. While assessing the MBC, the aqueous and ethanolic extracts of A. paeoniifolius and tetracycline hydrochloride exhibited bactericidal activity against F. nucleatum at all concentrations. The ethanolic extract of Amorphophallus paeoniifolius and tetracycline hydrochloride showed bactericidal action, whereas the aqueous extract exhibited bacteriostatic action against P. gingivalis. The aqueous and ethanolic extracts of A. paeoniifolius showed bacteriostatic action, whereas tetracycline hydrochloride showed bactericidal action against P. intermedia. Conclusion: Both aqueous and ethanolic extracts of A. paeoniifolius showed antibacterial activity against standard strains of P. gingivalis, P. intermedia, and F. nucleatum. The ethanolic extract showed a significant antibacterial effect against the selected microorganisms when compared to the aqueous extract of A. paeoniifolius.
