Chamomile (Matricaria chamomilla L) has anti-inflammatory, antioxidant, analgesic, and bacteriostatic properties that could help control oral microorganisms such as Streptococcus mutans. The objective of this research was to determine the in vitro antibacterial effect of chamomile, in essential oil and infusion, on Streptococcus mutans. The experimental study used the Kirby Bauer technique, which involves depositing antibiotic-impregnated discs containing chamomile essential oil (35%), chamomile infusion (20%), chlorhexidine 0.12% (positive control group), and distilled water (negative control group) on blood agar plates inoculated with Streptococcus mutans ATCC 25175 (n=44 Petri dishes, 11 for each tested substance), evaluating the formation of an inhibition zone. Descriptive and inferential statistics were performed (p ≤ 0.05 considered significant). The results showed that chamomile essential oil exhibited an antibacterial effect on Streptococcus mutans, unlike chamomile infusion, which showed no effect. The mean inhibition zones were 7.15 mm for chamomile essential oil (Matricaria chamomilla L) and 25.09 mm for chlorhexidine, after 48 hours of incubation. It was concluded that chamomile essential oil exhibited an antibacterial effect on Streptococcus mutans.
