Purpose: Little is known about the antimicrobial potential of mouthwashes in Streptococcus mutans bacteria. The objective of this in vitro study was to investigate the antimicrobial effects of infant mouthwashes against those bacteria. Materials and Methods: S. mutans strain was used to perform inhibition zones by agar diffusion test. Brain Heart Infusion (BHI) agar dishes were divided in quadrants: G1 – cetylperidinium chloride (Cepacol Teen®); G2 – xylitol and triclosan (Dentalclean Garfield®); G3 – Malva sylvestris, xylitol (Malvatrikids Jr®) and G4 - phosphate buffer saline (PBS). After adjustment of bacteria, an aliquot of each group was plated on the BHI agar and transferred to an atmosphere at 37ºC for 48 hours to perform the inhibition zones measurements. The data was analyzed by one-way ANOVA for intergroup comparison (α = 0.05). Results: Inhibition zones were verified only to G1 (10.82 ± 2.13) and G3 (12.75 ± 1.04). No significant statistical difference was verified between G1 and G3 (p = 0.287) and G2 and G4 (p ≥ 0.05). Conclusion: Despite of the beneficial effects of mouthwashes, a combination of xylitol and triclosan was not effective to control S. mutans growth in this in vitro condition. Additional restrictions to regulate the antimicrobial substances selling and further clarification should be provided to population.
