The dental biofilm usually develops when improper cleaning andsterilizing of dentures is achieved. The aim of this study was to improve theacrylic material surface properties for minimizing the incidence of dental plaqueformation on acrylic dentures by lowering the surface energy.Method: The acrylic (polymethylmethacryate) surface modification was achieved byapplying a non-polar micro-coating on acrylic samples which was the dentalbaseplate wax. Two experimental groups used in this study, the control and thecoated groups with 10 samples each. The surface analysis was conducted using thecontact angle's technique. All samples soaked in salivary solution for 5 days. Themethylene blue dye material used as an indicative for the dental plaque formation.Results and conclusion: The surface analysis showed a significant decrease in thesurface hydrophilicity of the coated group by increasing the water contact angledegree values (P-value<0.05). The microscopic analysis by visual inspectionshowed a reduced formation of the dental biofilm on the acrylic samples. Withinthe limitations of this study, the suggested coating material can possibly reducethe incidence of the dental biofilm formation on acrylic dentures.
