A random sample of 2280 subjects aged 60 years or over from three areas of England were examined clinically in order to assess their dental health and needs. Between 33% (south of England) and 57% (north of England) were edentulous. Twenty per cent of all dentate subjects were edentulous in one arch and thus still required a complete denture. Amongst the dentate subjects geographical differences were small, but social class and behavioural differences were large. Dental non-attenders were the group who stood out as having much poorer oral health, averaging six fewer natural teeth than attenders. Nearly 50% of all teeth either had coronal fillings or needed them. Root caries was common, 20-22% of vulnerable teeth were affected and there was an age related increase in disease risk. The mean number of teeth with decayed roots per subject (0.8) was similar to the mean number with decayed coronal surfaces (0.9). Moderate tooth wear and moderate periodontal disease were both widespread. A minority of subjects had a functional dentition of 21 or more teeth. Major changes in the dental status of older adults have taken place in the last 30 years and these will continue, resulting in lower levels of edentulousness but a large need for maintenance of existing restorations.
从英格兰三个地区随机抽取了2280名60岁及以上的受试者进行临床检查，以评估他们的牙齿健康状况和需求。无牙者比例在33%（英格兰南部）至57%（英格兰北部）之间。所有有牙受试者中有20%在一个牙弓上无牙，因此仍需要一副全口义齿。在有牙受试者中，地域差异较小，但社会阶层和行为差异较大。不看牙医的人群口腔健康状况明显较差，平均比看牙医的人少6颗天然牙。几乎50%的牙齿要么有冠部充填物，要么需要进行冠部充填。根龋很常见，20%-22%的易感牙齿受到影响，且疾病风险随年龄增长而增加。每位受试者牙根龋坏牙齿的平均数量（0.8颗）与冠面龋坏牙齿的平均数量（0.9颗）相似。中度牙齿磨损和中度牙周病都很普遍。少数受试者拥有21颗或更多牙齿的功能性牙列。在过去30年里，老年人的牙齿状况发生了重大变化，这些变化还将持续，导致无牙情况减少，但对现有修复体的维护需求很大。
