Abstract Artificial saliva can benefit tooth degradation management; this study assesses the role of mucins in this process using a combination of techniques to assess wear and surface degradation. Different neutral and acidic artificial saliva solutions were investigated, focusing on the protective capability of mucins. Static immersion and reciprocating ball-on-flat tribometer tests were performed on bovine enamel samples. The calcium released into the test solutions were assessed using Atomic Absorption Spectrophotometry (AAS) and enamel surfaces were examined using Vertical Scanning Interferometry (VSI). The addition of mucins reduced the coefficient of friction and wear scar volumes for neutral pH solutions. In acidic conditions the addition of mucin did not affect the lubrication, however it significantly reduced the calcium release under tribological conditions.

牙组织的摩擦腐蚀：粘蛋白的作用

摘要 人工唾液有利于牙齿退化管理；本研究使用评估磨损和表面降解的技术组合来评估粘蛋白在该过程中的作用。研究了不同的中性和酸性人工唾液溶液，重点关注粘蛋白的保护能力。在牛釉质样品上进行静态浸入和往复式球对平面摩擦计测试。使用原子吸收分光光度法 (AAS) 评估释放到测试溶液中的钙，并使用垂直扫描干涉仪 (VSI) 检查牙釉质表面。添加粘蛋白降低了中性 pH 溶液的摩擦系数和磨痕体积。在酸性条件下，添加粘蛋白不会影响润滑，
