Streptococcus Dentisani y su acción anticariogénica

Abstract

Dental decay is the most common disease in the oral cavity, it harbors several bacterial species that coexist in harmony with each other; nonetheless, when there is an imbalance between intrinsic and extrinsic factors triggered in the oralenvironment, opportunistic pathogens take advantage and proliferate, establishing colonies and niches. The increase of microorganisms modifies the pH and as a consequence of this event, dysbiosis occurs, facilitating the increase of oral pathogens. Probiotic microorganisms can mitigate or neutralize the proliferation of pathogens. This literature review aims to investigate the mechanisms of anti-cariogenic action of Streptococcus dentisani sp. nov in relation to Streptococcus mutans. A search of scientific articles was carried out in four databases PubMed, Scopus, Proquest, and Web of Science corresponding to the last 10 years of antiquity, where 72 articles were found from which 60 were selected. Streptococcus dentisani produce bacteriocins thatinteract in the cell wall of S. mutans causing pores that induce lysis of the bacteria,in turn, they can survive at acid pH and raise it promoting spatial competition withother microorganisms.
