研究:人类毛发提取角蛋白制成牙膏,可修复牙釉质并预防龋齿_蜘蛛资讯网

,其结构和功能与天然牙釉质高度相似。实验室测试表明,基于角蛋白的治疗方案能够完全阻止龋齿的进一步发展,并封闭暴露的神经通道,从而缓解牙齿敏感问题。与传统的含氟牙膏相比,角蛋白能够形成一层致密的矿物质层,不仅提供结构保护,还能缓解症状,有望减少早期损伤牙齿对补牙或牙冠的需求。在研究中,科学家从羊毛中提取了角蛋白。当该蛋白质应用于牙齿表面时,会形成类似晶体的支架结构,随着时间推移,它会持续吸引钙和磷酸

磷酸根离子,最终形成一层类似牙釉质的保护性涂层。伦敦国王学院的博士研究员萨拉・盖马(Sara Gamea)表示:“这种技术弥合了生物学与牙科之间的差距,提供了一种模仿自然过程的环保生物材料。”她还指出,角蛋白可以从生物废料(如毛发和皮肤)中可持续地获取,避免了传统修复牙科中使用的有毒且不耐用的合成树脂。此外,角蛋白的自然颜色更接近牙齿本身,修复后的效果更加自然,不易被察觉,在提升临床效果的同时提高
