Purpose: Denture plaque tends to form on the surface of the resins that are used as denture base materials, and Candida spp., including Candida albicans, are said to be causative organisms of denture stomatitis. Thus, modifying the surface properties of the resin to make it more difficult for denture plaque to adhere is very useful in terms of oral hygiene. In order to evaluate the usefulness of surface treatment with straight silicone, in this study we used heat-polymerized acrylic resin (polymethylmethacrylate [PMMA]) as the test material, and performed C. albicans adhesion test, a protein adsorption test and contact angle measurements with distilled water. Results: Significantly fewer C. albicans adhered and significantly less protein adsorbed in the coated group than in the control group or the buff-polished group (P<0.01). The angle of contact with distilled water in the coated group was significantly larger than in the control group or buff-polished group (P<0.01). Conclusion: Coating with straight silicone easily succeeded in improving the surface properties of PMMA used as the denture base material so that it became difficult for C. albicans to adhere, suggesting that an important property can be acquired clinically.
