In Vitro Antibacterial Activity of Nano Silver Ion Substituted Poly Acrylic Acid Films on Titanium by Plasma Polymerization.
Antibacterial activity of oral pathogens such as Streptococcus mutans, Streptococcus sobrinus when silver ion immobilized on commercially pure (CP) titanium (Ti) surface was investigated in this study. Plasma-polymerized acrylic acid to have carboxyl group was deposited on CP-Ti surface and then ion-exchanged with Ag+ ions in 0.1 N AgNO3. In anti-adherent experiment, antibacterial activity was tested using broth culture methods. The biofilm formation assay was performed using semi-defined biofilm medium with sucrose. The silver coated CP-Ti completely inhibited the growth of S. mutans and S. sobrinus. In addition, the biofilm formation was significantly inhibited in silver-coated CP-Ti group.
