一个新的指数，由不同的观察者的牙齿磨损评级的适用性进行了测试。四名牙医，谁是第一次校准使用的评分系统，然后进行interexaminer协议测试之前和之后的实地研究，共167个人在他们的私人牙科诊所。记录牙齿的切/咬合状态，包括咬合和牙齿磨损。检验员间一致性检验在对主要磨损组进行评级时证明是令人满意的，但在对子类别进行评级时则不那么好。然而，第一次和第二次测试之间的协议显着改善。组成实地研究小组的个体可能不代表一般的斯堪的纳维亚人群。牙齿缺失相对较少，牙齿恢复良好。只有最高年龄组（80-89岁）显示出任何程度的磨损最严重。然而，在最年轻的年龄组（20-29岁）中已经观察到20%的牙齿磨损到牙本质中。这些牙齿只是两个颌骨的门齿和犬齿。总之，我们发现，在提供了足够的系统使用培训后，该指数应该非常适合不同研究人员对大群体人群的牙齿磨损进行评估，并且牙齿磨损可能是斯堪的纳维亚城市人群中相对较小的问题定期牙科护理。
The suitability of a new index for rating dental wear by different observers was tested. Four dentists, who were first calibrated using the scoring system and then subjected to an interexaminer agreement test before and after a field study, rated 167 individuals in total in their private dental practices. The incisal/occlusal state of the teeth with regard to restorations and dental wear was recorded. The inter-examiner agreement test proved satisfactory when rating main groups of wear but not so good when rating subcategories. However, a marked improvement in agreement developed between the first and the second test. The individuals composing the field study group are probably not representative of Scandinavian populations in general. Relatively few teeth were missing, and teeth were well restored. Only the highest age group (80-89 years) displayed the most severe degree of wear to any extent. However, wear into the dentin was observed in 20% of the teeth already in the youngest age group (20-29 years). These teeth were solely incisors and canines of both jaws. In conclusion, we found that the index should be well suited for the evaluation of dental wear in large groups of people by different investigators after adequate training in use of the system has been provided and that tooth wear may be a relatively small problem in urban Scandinavian populations with regular dental care.
