牙科行业越来越担心牙齿磨损程度不可接受，而且这种情况越来越普遍。迄今为止，还没有什么流行病学证据来阐明这个问题，因此本研究旨在提供英格兰东南部牙科就诊人群样本中牙齿磨损流行率的基线数据。一定程度的牙齿磨损是正常的，并且会在一生中不断恶化。对于老年患者来说可以接受的牙齿佩戴方式对于年轻患者来说就不同了。因此，有必要为不同年龄组指定可接受的牙齿磨损水平的阈值，以便就不可接受的牙齿磨损水平的普遍程度得出现实的结论。在接受检查的 1007 名患者中，只有 9 名患者的牙列完全未磨损。检查了超过 93,500 个牙齿表面，其中 5.1% 的磨损超过了阈值。尽管史密斯和奈特 (1984) 的一项早期研究中提出的阈值有所提高，但这些患者的牙齿磨损程度仍然较高。男性比女性有轻微的磨损倾向，但后牙缺失数量与前牙磨损之间没有临床显着关系。
The dental profession is becoming increasingly concerned about unacceptable levels of toothwear and there is an impression that the condition is becoming more prevalent. There is, as yet, little epidemiological evidence to illuminate the question and so this study is therefore intended to provide baseline data on the prevalence of toothwear in a sample of the dental attending population of South East England. A degree of toothwear is normal and progresses throughout life. Toothwear which is acceptable in an older age group would not be so with younger patients. It is therefore necessary to designate threshold values of acceptable levels of toothwear for different age groups to reach realistic conclusions about the prevalence of unacceptable levels of toothwear. Of the 1007 patients examined only nine had completely unworn dentitions. More than 93,500 tooth surfaces were examined and of these 5.1% had wear which exceeded the threshold values. Despite increasing the threshold values for the older age groups from those proposed in an earlier study by Smith & Knight (1984), these patients still had higher levels of unacceptable toothwear. There was a slight tendency for men to have more wear than women, but there was no clinically significant relationship between the number of missing posterior teeth and wear of the anterior teeth.
