A follow-up study of the dental health of children resident in two towns in south-west Scotland, one of which had fluoridated water until 1983, was carried out at the end of 1988. Comparison with an identical 1980 study allowed trends in the prevalence of caries to be examined. In 1988, the mean, decayed, missing and filled deciduous teeth (dmft) score for 5-year-old children in Stranraer, the formerly fluoridated town, was 3.08, 24 per cent worse than the score of 2.48 reported in 1980. In Annan, mean dmft for 5-year-old children was 3.18 in 1988, 27 per cent lower than the 1980 dmft score of 4.38. The difference in caries prevalence between the two towns in 1988 was a non-significant 3.1 per cent compared with the 44 per cent difference found in 1980. Similar trends in caries prevalence were also found in 10-year-old children with mean DMFT scores of 2.28 in Stranraer and 2.56 in Annan in 1988, a 10.9 per cent difference compared with the 50 per cent difference reported in 1980. The Stranraer DMFT score was 37.4 per cent higher than the DMFT of 1.66 recorded in 1980, while in Annan, the mean DMFT of 2.56 was 23.6 per cent lower than the 1980 score of 3.35. The comparison confirms a trend to lower caries levels in Annan children in line with the general trend in caries prevalence in much of western Europe. However, despite the almost universal use of fluoride toothpaste, caries prevalence in Stranraer children has increased since fluoridation ceased to almost parity with children in the non-fluoridated area. This study shows that there is still a benefit to be gained in terms of lower caries rates by implementing water fluoridation despite the general decline in dental caries.
1988年底，对居住在苏格兰西南部两个城镇的儿童的牙齿健康状况进行了一项跟踪研究，其中一个城镇的水氟化一直持续到1983年。与1980年的一项相同研究进行比较，从而得以考察龋齿患病率的变化趋势。1988年，曾实施水氟化的斯特兰拉尔镇5岁儿童的乳牙龋失补牙均指数（dmft）平均分为3.08，比1980年报告的2.48分高出24%。在安南，1988年5岁儿童的dmft平均分为3.18，比1980年的4.38分低27%。1988年，两个城镇之间的龋齿患病率差异为3.1%，不具有统计学意义，而1980年的差异为44%。1988年，10岁儿童的龋齿患病率也呈现出类似趋势，斯特兰拉尔镇的恒牙龋失补牙均指数（DMFT）平均分为2.28，安南为2.56，差异为10.9%，而1980年报告的差异为50%。斯特兰拉尔镇的DMFT分数比1980年记录的1.66高出37.4%，而在安南，2.56的平均DMFT分数比1980年的3.35分低23.6%。该比较证实，安南儿童的龋齿水平呈下降趋势，这与西欧大部分地区龋齿患病率的总体趋势一致。然而，尽管含氟牙膏几乎被普遍使用，但自停止水氟化以来，斯特兰拉尔镇儿童的龋齿患病率有所上升，几乎与未实施水氟化地区的儿童持平。这项研究表明，尽管龋齿总体发病率有所下降，但实施水氟化在降低龋齿发病率方面仍有益处。
