Fixed orthodontic treatment produces a greater accumulation of dental biofilm in patients, and adequate oral hygiene complemented with mouthwashes is necessary. Objective. The purpose of this study was to evaluate the antibacterial action of mouthwashes for orthodontic use on Streptococcus Mutans in patients with fixed orthodontic appliances. Materials and method. A quasi-experimental, comparative, longitudinal, single-blind, quantitative approach study was carried out with a sample size of 20 patients distributed in two study groups for the CFU count, as well as a positive and a negative control to determine the inhibitory halo. Results. Vitis® Orthodontic and Ortolacer mouthwashes had a decrease in the CFU count of Streptococcus Mutans up to 48.3% (p=0.00) and 53.2% (p=0.00) respectively; likewise, there is a greater antibacterial action on Streptococcus Mutans of Vitis® Orthodontic mouthwash than Ortolacer mouthwash (p-value=0.009); Likewise, with a p-value = 0.000 < 0.05 at 24 and 48 hours there is a significant statistical difference in anaerobiosis indicating that Vitis® Orthodontic mouthwash generates a greater inhibitory halo on Streptococcus Mutans. Conclusions. Vitis® Orthodontic and Ortholacer mouthrinses decrease the CFU count of Streptococcus Mutans in patients. In addition, both mouthwashes in anaerobiosis have inhibitory action on Streptococcus Mutans. However, there is a greater antibacterial action of Vitis® Orthodontic mouthwash on Streptococcus Mutans.
