Efeito antibacteriano da quitosana contra Streptoccocus mutans: uma alternativa para enxaguatório bucal no controle e prevenção da cárie dentária?

Objective: This study aimed to review the literature on chitosan antibacterial activity against Streptococcus mutans, assessing this biopolymer’s potential for caries control and prevention. Materials and Methods: A search for studies in the “Pubmed” database was carried out, using the terms “Chitosan and Streptococcus mutans.” Eightyeight articles were found, and no filter was used in the search. Results: In general, chitosan inhibited the adhesion and biofilm of Streptococcus mutans, tested in different concentrations, exposure time, molecular weight, and pH. Therefore, chitosan has antibacterial activity against Streptococcus mutans. Conclusion: Although it can demonstrate the potential for use as a component of an oral product, more studies need to be conducted and analyzed to prove its ability to prevent and control dental caries
