Many methods are available for the grading of tooth wear, but their ability to assess the progression of wear over time has not been studied frequently. The aim was to assess whether the occlusal/incisal grading scale of the Tooth Wear Evaluation System (TWES) was sensitive enough for the detection of tooth wear progression from 14 to 23 years of age. A total of 120 sets of dental casts were gathered from 40 people, of whom impressions were made at 14, 18 and 23 years. The TWES was used to assess loss of clinical crown height throughout the entire dentition. There was a significant difference in the TWES scores between the three age groups on all teeth (Friedman tests; P < 0.005 in all cases). Post hoc Wilcoxon tests revealed that the difference between the scores between 14 and 18 years and between 18 and 23 was significant for most teeth. It was concluded that the TWES is sensitive enough to detect changes in tooth wear over time.
目前有多种方法可用于牙齿磨损的分级，但它们评估磨损随时间进展情况的能力尚未得到充分研究。本研究旨在评估牙齿磨损评估系统（TWES）的咬合/切缘分级量表对于检测14至23岁人群牙齿磨损进展是否足够敏感。研究共收集了来自40人的120套牙模，这些人分别在14岁、18岁和23岁时制取了印模。采用TWES评估全牙列临床冠高度的丧失情况。所有牙齿在三个年龄组之间的TWES评分均存在显著差异（Friedman检验；所有情况P < 0.005）。事后Wilcoxon检验显示，对于大多数牙齿，14岁与18岁之间以及18岁与23岁之间的评分差异具有统计学意义。研究得出结论，TWES对于检测牙齿磨损随时间的变化足够敏感。
