The objective of this research was to determine the antibacterial and antifungal in vitro effect of the essential oils of Mentha piperita (peppermint), Origanum vulgare (oregano), and Cymbopogon citratus (lemongrass) using the disc diffusion method on Streptococcus mutans ATCC 25175, Lactobacillus acidophilus ATCC 10746, and Candida albicans ATCC 90028. The essential oils of these plants were obtained through the steam distillation method. For the microbiological analysis, the essential oil of peppermint was used at concentrations of 50% and 100%, oregano at 50% and 100%, and lemongrass at 50% and 90%. To obtain the 50% and 90% concentrations, the oils were diluted in distilled water and DMSO (dimethyl sulfoxide). These essential oils were compared with nystatin as the positive control (for fungi) and chlorhexidine gluconate at 0.12% (for bacteria). Distilled H2O and DMSO were used as negative controls. The in vitro sensitivity tests showed the following results: of the three essential oils, oregano had the greatest effect on Streptococcus mutans. For Lactobacillus acidophilus and Candida albicans, lemongrass had the greatest effect. The essential oils of oregano and lemongrass were more effective in antibacterial and antifungal activity than the positive controls, chlorhexidine at 0.12% and nystatin, except for Mentha piperita (peppermint) at 50%, whose action was weaker than the positive controls.
