The aim of this study was to assess the relative contribution of dental services to the changes and geographical variations in caries status of 5- and 12-year-old children in England and Wales in the 1980s. A secondary aim was to assess the association between caries experience and social factors. An ecological study analysing data at a district health authority level in England and Wales was conducted. Twenty-eight, 43 and 34 per cent of the variations in 5-year-old dmft in 1985, 1987 and 1989 respectively were explained by dental service activity indicators and 53, 62 and 57 per cent by social factors. Twenty-nine per cent of the variation in 12-year-old DMFT in 1988 was explained by dental service activity indicators and 46 per cent by social factors.
本研究旨在评估20世纪80年代英格兰和威尔士5岁及12岁儿童龋齿状况的变化及地理差异中牙科服务的相对贡献。次要目的是评估龋齿经历与社会因素之间的关联。开展了一项生态学研究，分析英格兰和威尔士地区卫生当局层面的数据。1985年、1987年和1989年，5岁儿童dmft变化中分别有28%、43%和34%可由牙科服务活动指标解释，53%、62%和57%可由社会因素解释。1988年，12岁儿童DMFT变化的29%可由牙科服务活动指标解释，46%可由社会因素解释。
