In this study, we evaluated the effect of surface charged dental glass-ceramics on bacterial adhesion. We modified the surface charges of dental glass-ceramics through the electrical polarization process. The regulated surface charge was evaluated by the thermally stimulated depolarization current curves. The modified and non-modified dental glass-ceramics were incubated with streptococcus mutans for 24 h after immersion of specimens in artificial saliva with mucin. Negatively charged surface showed lower percentage of bacterial adhesion compared with control and positively charged surface. We could successfully suppress the bacterial adhesion to the regulated surface charged dental glass-ceramics through the electrical polarization process.
