Wear testing of five restorative materials was carried out against plates of human dentine using a wear machine specifically designed to simulate the masticatory cycle. The results showed that dentine is substantially less wear resistant than enamel when compared to previous findings. Amalgam produced no measurable wear of dentine, conventional composite produced extreme destruction and porcelain produced the greatest amount of wear. Great care should be taken with the choice of restorative material when opposing dentine.
使用专门设计用于模拟咀嚼周期的磨损试验机，对五种修复材料与人类牙本质板进行了磨损测试。结果表明，与先前的研究结果相比，牙本质的耐磨性明显低于牙釉质。汞合金对牙本质没有可测量的磨损，传统复合材料造成了极端破坏，而陶瓷产生的磨损量最大。在选择与牙本质相对的修复材料时应格外小心。
