RESUMO
OBJECTIVE To assess the adherence ability of Candida albicans to two denture base resins with different surface roughness.METHODS In adhesion assays,two denture base resins were made into standard test samples with different surface roughness.Suspension of C.albicans(ATCC 10261) strain was used to adhere on the test samples,and cultured to observe the adhesive effect of a mixed salivary pellicle with Candida to these surfaces.RESULTS In glass surface group,the amount of C.albicans adhering to heat-curing denture base resins was 15.33?2.80,and the amount of C.albicans adhering to Valplast flexible denture resin was 13.67?2.94;In gypsum surface group,the amount of C.albicans adhering to heat-curing denture base resins was 22.67?4.84,and the amount of C.albicans adhering to Valplast flexible denture resin was 21.17?3.31.Significantly greater adhesion of C.albicans to rough surfaces rather than smooth surfaces of the same material was found,at the same time C.albicans had different adhesive ability on different denture base resins(P
