Abstract
AIM: The study aimed at investigating in vitro antimicrobial activity of ethanolic extract of propolis (EEP) and water extract of propolis against two main cariogenic oral pathogens: Streptococcus mutans and Lactobacillus acidophilus. MATERIAL AND METHODOLOGY: Propolis was obtained from beehives in the Jhabua region of India. Ethanolic and water extracts were prepared at concentrations of 5% and 20% weight/volume (w/v). To support the results, a positive control (chlorhexidine 0.2%) and a negative control (distilled water) were used. S. mutans was cultured on brain-heart infusion agar and L. acidophilus was cultured on De Man, Rogosa, and Sharpe agar. RESULTS: The results showed that at concentrations of 5% and 20%, EEP was effective against S. mutans and L. acidophilus. However, at similar concentrations, water extract was effective only against L. acidophilus. The highest activity was shown by chlorhexidine (0.2%) with mean zones of inhibition of 13.9 mm and 15.1 mm against S. mutans and L. acidophilus, respectively. CONCLUSION: It can be concluded that the propolis extracted from tribal regions of Jhabua possesses antibacterial efficacy against S. mutans and L. acidophilus.
