    The aim of this study was to determine the antibacterial effect of three plant-based compounds: Stevia rebaudiana, Camellia sinensis, and Origanum vulgare, against Streptococcus mutans. An in vitro experimental design methodology was used, with an analytical method and applied type. Treatments were applied to Petri dishes with Streptococcus mutans strains, using 10 plates for each treatment and two control groups. The results revealed that, of the three plant-based compounds tested, two showed antibacterial effects against Streptococcus mutans. For Origanum vulgare, inhibition halos of 32.09 mm were obtained at 24 hours and 31.80 mm at 48 hours. For Camellia sinensis, inhibition halos were 25.06 mm at 24 hours and 24.74 mm at 48 hours. However, Stevia rebaudiana did not show an antibacterial effect as its inhibition halos were 0 mm. Therefore, it was concluded that the antibacterial compounds that did show antibacterial effects did not show significant differences compared to the positive control used, 0.12% Chlorhexidine Gluconate (p>0.05).
