In vitro study evaluates the antibacterial effects of lemongrass and basil extracts against Streptococcus mutans, highlighting their natural potential.

Key Points

This research aims to assess the inhibitory effects of lemongrass and basil extracts on the growth of Streptococcus mutans.
Conducted an in vitro study with serial dilution and colony-counting methods.
Evaluated the antibacterial effects of various concentrations (100%, 50%, 25%, 12.5%) of the extracts against S. mutans.
Determined Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC).
Used chlorhexidine and negative controls for comparison; analyzed data with Kruskal-Wallis test and Mann-Whitney post hoc test.
Lemongrass and basil extracts demonstrated significant antibacterial activity against S. mutans.
MIC was determined to be 12.5%, while MBC was 25%.
Significant differences were observed between treatment and control groups (p = 0.005).
No significant differences were found among varying concentrations of the extracts.
