Abstract This paper investigates the wear behaviour of remineralised human dental enamel. Polished enamel flat surface samples were first demineralised in an acid solution and then remineralised in whole human saliva. They were opposed by enamel cusps in wear tests. Wear depth was measured by a profilometer and the wear surface and subsurface were examined by electron microscopy. The results show that the pores in the top surface layer collapse during wear and form a particle layer which is subsequently removed by ploughing/delamination. For enamel underneath, the dominating wear mechanism is delamination. Remineralised enamel is extremely vulnerable since the measured wear rate is 4 - 15 times that for sound enamel.

再矿化人牙釉质的磨损行为：一项体外研究

摘要 本文研究了再矿化人牙釉质的磨损行为。抛光釉质平面样品首先在酸性溶液中脱矿质，然后在整个人类唾液中再矿化。在磨损测试中，它们遭到搪瓷尖头的反对。通过轮廓仪测量磨损深度，并通过电子显微镜检查磨损表面和次表面。结果表明，顶面层中的孔在磨损过程中塌陷并形成颗粒层，随后通过犁耕/分层去除。对于下面的搪瓷，主要的磨损机制是分层。再矿化搪瓷极其脆弱，因为测量的磨损率是完好搪瓷的 4 - 15 倍。
