俄罗斯等国研究人员开发出可修复牙表的抗菌新材料

Core Viewpoint - An international team led by Russian researchers has developed a new dental treatment material that inhibits harmful bacteria and mimics the microstructural morphology of tooth surfaces, showing significant potential for clinical applications in oral health [1][2]. Group 1: Material Development - The new dental coating material is created using polyhydroxyquinoline and nanocrystalline hydroxyapatite, the main mineral component of tooth enamel [1]. - The coating solidifies and forms a uniform thin layer on damaged teeth after approximately 30 minutes of application [1]. Group 2: Performance Characteristics - The coating material exhibits a microhardness value that is only 10% to 20% lower than that of healthy tooth enamel, indicating its mechanical properties are similar to natural enamel [2]. - Scanning electron microscope tests show that the coating adheres tightly to the enamel and mimics the natural texture of tooth surfaces [2]. Group 3: Antibacterial Properties - The coating material is effective in destroying the cells of Streptococcus bacteria, inhibiting their activity and preventing plaque formation [2]. - The research highlights the dual functionality of the developed dental biomimetic technology, showcasing both antibacterial and solidifying properties, which could be significant for future clinical applications in dentistry [2].
