近日,伦敦玛丽女王大学(Queen Mary University of London)宣布,该校科研人员开发了一项名为Varnish VLC的新型牙科涂层技术,旨在保护牙齿免受龋齿和酸蚀的侵害。

据介绍,这项技术借鉴了用于保护桥梁(如福斯桥)的先进工业涂层技术。Varnish VLC使用的片状玻璃技术已成功用于保护油罐、容器和管道免受腐蚀,这种技术因其优秀的防潮和抗恶劣环境能力而受到广泛应用。

这项技术首次被科学家应用于龋齿预防。Varnish VLC通过模拟牙釉质的自然特性,提供了一种有效的方法来减少牙齿磨损和防止损坏。

研究显示,龋齿影响着英国三分之一的儿童和近半数成年人,不仅导致显著不适,还会带来昂贵的治疗费用。尽管NHS每年投入数百万英镑,但目前的解决方案(如氟化物涂层和渗透树脂)并未能提供长期有效的保护。

相比传统治疗方法,Varnish VLC具有更好的耐磨性和抗酸蚀保护能力,同时能保持牙齿的自然外观。初步的体外研究证实,在耐磨性和抗酸蚀保护方面,Varnish VLC的表现优于现有治疗方法。

Varnish VLC还具有微创应用的优势:施用过程中不会产生气溶胶,为患者和牙科专业人员提供了更安全的治疗环境。

项目首席研究员、伦敦玛丽女王大学牙科生物材料讲师Saroash Shahid博士表示:“我们相信这项技术有潜力改变预防牙科,尤其是儿童牙科预防领域。”

目前,伦敦玛丽女王大学正在开展为期六个月的临床试验,以评估Varnish VLC在实际应用中的效果。同时,大学正与PSP Dental(英国牙科产品制造商)合作,计划将这项技术推广至英国及全球的牙科诊所。
