Abstract

Abstract: This study evaluated the effect of sodium hexametaphosphate (HMP), administered alone or in combination with fluoride (F), on dual-species biofilms of Streptococcus mutans and Candida albicans . Biofilms were treated with HMP solutions at 0.25%, 0.5% and 1%, alone or combined with F (0.05%), and compared by evaluating their structure and quantifying the colony-forming units (CFUs), metabolic activity, production of biomass and extracellular matrix components. All HMP-containing solutions were capable of reducing metabolic activity, the biofilm biomass, and the extracellular matrix components. Furthermore, the treatment with 1% HMP/F significantly reduced the CFUs of S. mutans, although it showed no effect on the CFUs of C. albicans, in the dual-species biofilms. In general, the combination of HMP and F influenced all the parameters analyzed from dual-species biofilms, except the CFUs of C. albicans .
