Abstract: The aim of this study was to evaluate the effect of modified heat cured polymethyl methacrylate denture base (PMMA) or varnish coating of the denture base on candida albicans adhesion and porosity. First experimental group was prepared by addition of 15% phosphoric acid 2-hydroxyethyl methacrylate ester with polymethyl methacrylate monomer. While second experimental group prepared by varnish layer coating after material processing, these groups were compared with the control one. Three groups of vertex acrylic resin used as control, mPMMA and varnish coated group (PPH Cerkamed Wojciech Pawlowski, Poland). The inverted light microscope was used to measure the candida albicans adherence after one week and one month of processing. Two-way ANOVA, LSD test, T- test and Dunnett T3 were performed on data.  Modified Acrylic resin showed highly significant reduction in candida albicans adhesion and porosity, also for varnish coating group showed highly significant reduction in candida albicans adhesion and porosity test.
