Evaluation of the antimicrobial potential of fluoride-free mouthwashes against Scardovia wiggsiae

Hydrogen peroxide- and CPC-containing mouthwashes exhibited the highest antimicrobial potential against S. wiggsiae and may serve as effective fluoride-free alternatives for high-risk populations. Essential oil-based formulations provided moderate benefits, whereas zinc chloride and chlorine dioxide showed minimal efficacy. These findings underscore the importance of selecting appropriate antimicrobial agents for biofilm control and caries prevention. Further in vivo studies are necessary to validate long-term effectiveness in clinical settings.
