Background: It is well known that the use of denture cleansers can reduce Candida albicans biofilm accumulation;
however, the efficacy of citric acid denture cleansers is uncertain. In addition, the long-term efficacy of this denture
cleanser is not well established, and their effect on residual biofilms is unknown. This in vitro study evaluated the
efficacy of citric acid denture cleanser treatment on C. albicans biofilm recolonization on poly(methyl methacrylate)
(PMMA) surface.
