A critical examination of the literature for dental wear publications highlighted three distinct areas, clinical data, laboratory data and the simulation of the clinical situation data. The imprecision of the clinical data values from direct and indirect in vivo methods renders the clinical data compromised at best. Laboratory data showed a focus on finding a correlation between simplistic laboratory abrasive wear resistance studies and established materials science laboratory techniques, but with no actual correlation identified. Replication of the masticatory cycle in the mouth in the form of an oral wear simulator has focussed more on the wear testing devices rather than the wear quantification methods. As a result, the data acquisition variables in the x- and y-planes need to be examined to consider how they can influence the accuracy and precision of the laboratory wear measurements recorded in the dental literature. The current approach was undertaken using the teaching tool outlined in “The First Three Questions”.

磨损测试和磨损面分析的准确度和精度：故事的两个方面

对牙齿磨损出版物文献的严格审查强调了三个不同的领域：临床数据、实验室数据和临床情况数据的模拟。直接和间接体内方法的临床数据值的不精确性充其量使得临床数据受到损害。实验室数据显示，重点是寻找简单的实验室耐磨性研究与已建立的材料科学实验室技术之间的相关性，但尚未发现实际的相关性。以口腔磨损模拟器的形式复制口腔中的咀嚼周期更多地关注磨损测试设备而不是磨损量化方法。因此，需要检查 x 和 y 平面中的数据采集变量，以考虑它们如何影响牙科文献中记录的实验室磨损测量的准确性和精密度。目前的方法是使用“前三个问题”中概述的教学工具进行的。
