은 이온코팅에 의한 구강미생물 부착 억제 효과

Abstract

Commercially pure titanium has been adopted by the dental profession as a metal for crown, bridge, and dental implant for more than a decade, because of their high toughness and excellent biocompatibility. Ionic silver shows that highest antibacterial and anti-adherent activity among metal ions. Dental and orthopedic implants-related bacterial infection is a major rising clinical problem. In order to reduce the incidence of bacteria infection surrounding the infections, several biomaterial surface treatments have been proposed. Plasma treatment is currently used in surface and interface engineering for improving adhesion, hydrophobicity, hydrophilicity, printability, corrosion resistance, selectivity, or for surface etching and cleaning. The aim of this study was to investigate anti-bacterial activity of oral pathogens such as Streptococcus mutans ATCC 31989, Porphyromonas gingivalis ATCC 33277, and Staphylococcus aureus ATCC 29231 also cytotoxicity of MG-63 cells when silver ion released from pure titanium surface.
