    The objective of this study was to determine the inhibitory effect of the ethanolic extract of Bidens pilosa (Amor seco) compared to Colgate Plax® and 0.12% Chlorhexidine Gluconate against strains of Streptococcus mutans. The study was experimental, prospective, longitudinal, and analytical. The population consisted of Streptococcus mutans strains (ATCC 25175), and the sample consisted of 40 Petri dishes. The strains were reactivated and cultured on Blood Agar, where 6 mm diameter wells were made, and approximately 100 µl of the ethanolic extract of Bidens pilosa (Amor seco) were added in the following concentrations: 0.8/10, 1/10, and pure. The results were compared with 0.12% Chlorhexidine Gluconate as a positive control, distilled water as a negative control, and Colgate Plax® mouthwash. The results showed that the 0.8/10 and 1/10 concentrations of the ethanolic extract of Bidens pilosa (Amor seco) did not present any inhibition zone at any time. However, the pure ethanolic extract produced an average inhibition zone of 11.98 mm at 24 hours and 11.80 mm at 48 hours. Furthermore, a stronger inhibitory effect was observed with the positive control, 0.12% Chlorhexidine Gluconate, and a lesser inhibitory effect compared to Colgate Plax® mouthwash against the Streptococcus mutans (ATCC 25175) strain.
