Interaction of Erosion and Attrition on Tooth Wear

本研究的目的是考察几种不同的酸性溶液和不同的含漱剂对牛牙釉质冲击-滑动特性的影响。这些结果表明，所用材料的化学成分和pH值不同，牙釉质的冲击-滑动磨损也不同。研究还表明，牙釉质冲击滑动磨损存在粘着磨损和化学磨损等多种磨损机制，不同材料冲击滑动磨损后的磨损量和表面硬度因材料化学成分和pH浓度的不同而不同。酸性饮料和口香糖的频率以及它们的消费方式在临床管理中可能很重要。

The purpose of this study was to examine the influence of several different acidic solutions and various mouthrinses on impacting-sliding characteristics of bovine enamel. These results implied that the impacting-sliding enamel wear differed according to chemical components and pH of the material used. It was also suggested that various wear mechanisms such as adhesive wear and toribochemical wear were involved in the impacting-sliding enamel wear.The wear loss and surface hardness number of enamel after impacting-sliding wear test were differed among the materials used, depending on their chemical components and pH concentration. The frequency of acidic drinks and mouthrinses and how they are consumed may be important in clinically management.
