This study examined the influence of carbon chain length of fluorinated alkyl acrylate on bacterial adhesion to the surface of test specimens. Perfluorobutylethyl acrylate (C4F), perfluorohexylethyl acrylate (C6F), perfluorooctylethyl acrylate (C8F), and perfluorodecylethyl acrylate (C10F) were used as fluorinated alkyl acrylate monomers. All specimens with the fluoro-monomer added exhibited significantly higher water-shedding and oil-shedding surface characteristics when compared to control (MMA/PMMA). Furthermore, contact angle for droplets of water and dodecane on the fluoromonomer-added specimens increased with carbon chain length of the perfluoroalkyl groups. Bacterial adhesion was significantly suppressed on the fluoromonomer-added specimens, both the saliva-uncoated and -coated specimens. In addition, the number of Candida albicans adhering to both the saliva-uncoated and -coated fluoromonomer-added specimens decreased with an increase in perfluoroalkyl carbon chain length. The results suggest that the application of fluorinated alkyl acrylate to denture base resin can modify the surface characteristics, and that fluorinated alkyl acrylate with long carbon chains of C8F and C10F successfully inhibit bacterial adherence to the resin surface.
