The objective of this research was to assess the antibacterial activity of the essential oil of Cinnamomum zeylanicum (cinnamon) compared to 0.12% chlorhexidine against Streptococcus mutans ATCC 25175 "in vitro". The study was experimental, prospective, and longitudinal. The essential oil was obtained using the steam distillation method from the bark of Cinnamomum zeylanicum (cinnamon). For microbiological analysis, the essential oil was used at 100%, and the well-agar diffusion method was applied. Thirty Petri dishes with Muller Hinton agar were prepared, each with a 6 mm diameter well saturated with cinnamon essential oil and 0.12% chlorhexidine (DENTODEX®). The samples were incubated at 37°C, and inhibition zones were measured and recorded at 72 and 120 hours. The essential oil was compared to 0.12% chlorhexidine as a positive control for Streptococcus mutans ATCC 25175, with sterile distilled water as the negative control. The data were processed using SPSS, and the T-Student statistical test was applied. The study concluded that the essential oil of Cinnamomum zeylanicum (cinnamon) showed stability and antibacterial activity "in vitro" against Streptococcus mutans ATCC 25175 at 72 and 120 hours. Chlorhexidine 0.12% showed greater antibacterial activity than the essential oil at 120 hours.
