    The objective of this research was to determine the antimicrobial activity of toothpaste with and without triclosan on Streptococcus mutans. The sample size was determined by sample size calculation, and the strain studied was of the ATCC 25175 type. The sample consisted of 40 Petri dishes, each with 4 wells of 5 millimeters in diameter, where 0.05 milliliters of toothpaste was placed, and the evaluation was done at 24 and 48 hours. The study was experimental in vitro. Data were evaluated using the SPSS v22 statistical package, employing the ANOVA test and Tukey’s multiple comparisons test. The results showed that toothpaste with triclosan exhibited an antimicrobial activity of 41.05 ± 3.58 mm on Streptococcus mutans at 24 hours and 39.75 ± 3.32 mm at 48 hours, while toothpaste without triclosan showed antimicrobial activity of 39.00 ± 4.05 mm, 37.8 ± 5.15 mm, and 39.15 ± 3.87 mm at 24 hours and 36.80 ± 4.14 mm, 35.85 ± 4.84 mm, and 37.45 ± 3.72 mm at 48 hours. It was also found that at 24 hours, toothpaste with and without triclosan did not present statistically significant differences. It is concluded that both toothpaste with and without triclosan are effective antimicrobial agents against Streptococcus mutans.
