This study evaluated the antibacterial effect of a visible light reactive TiO2/Ag nanocomposite thin film on dental orthodontic wire (STS 304 wire). The growth of S. mutans and A. actinomycetemcomitans was suppressed on the specimens coated with TiO2/Ag compared to the uncoated specimens. The antibacterial effect of the TiO2/Ag nanocomposite thin film was improved under visible light irradiation.
本研究评估了可见光反应性TiO₂/Ag纳米复合薄膜对牙科正畸钢丝（STS 304钢丝）的抗菌效果。与未涂层的标本相比，在涂有TiO₂/Ag的标本上变形链球菌和伴放线放线杆菌的生长受到抑制。在可见光照射下，TiO₂/Ag纳米复合薄膜的抗菌效果得到改善。
