Abstract

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.

Biofilm formation is a key virulence factor for a wide range of microorganisms that cause chronic infections.Here is the latest research on biofilm and infectious diseases.

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.

Biofilms
