Caries experience and oral cleanliness were measured in 1,453 3- and 4-year-old Edinburgh nursery schoolchildren living in areas of multiple urban deprivation and of non-deprivation in the city of Edinburgh. Children with poor oral cleanliness had a mean dmf value of 3.6 teeth compared with 1.6 teeth in those with good oral cleanliness. The greatest relative increases in caries experience were seen in the incisor and canine teeth and upon the occlusal and approximal surfaces. Children living in deprived city areas had a mean dmf value of 3.0 teeth compared with 2.0 teeth in those from non-deprived areas. This difference in caries experience was partially accounted for by the different standards of oral cleanliness found between the deprived and non-deprived areas. In the deprived areas there was a trend towards a high caries experience which was independent of the standard of oral cleanliness. The children were in considerable need of dental care. Only 23 percent of dmf teeth had been either extracted or restored.
对居住在爱丁堡市多个城市贫困地区和非贫困地区的1453名3至4岁的爱丁堡幼儿园儿童进行了龋齿经历和口腔清洁度测量。口腔清洁度差的儿童平均龋失补牙数（dmf）为3.6颗牙，而口腔清洁度好的儿童为1.6颗牙。龋齿经历相对增加最多的是门牙和犬齿以及咬合面和邻面。居住在城市贫困地区的儿童平均dmf值为3.0颗牙，而非贫困地区的儿童为2.0颗牙。这种龋齿经历的差异部分是由于贫困地区和非贫困地区口腔清洁度标准不同所致。在贫困地区，存在龋齿高发的趋势，且与口腔清洁度标准无关。这些儿童非常需要牙科护理。只有23%的龋失补牙已被拔除或修复。
