It is important that baseline studies of dental caries prevalence are available prior to the introduction of community water fluoridation. This survey was carried out during the winter of 1975/76 in the low-fluoride Barnsley Area (F= 0.1 parts/10(6)). Caries prevalence is in accord with that of other low-fluoride areas. The mean dmf was 4.5. For the group of children with rampant dental caries, the mean dmf value was much greater (11.3).
在引入社区水氟化之前，进行龋齿患病率的基线研究很重要。这项调查于1975/76年冬季在低氟的巴恩斯利地区（氟含量为0.1 ppm）开展。龋齿患病率与其他低氟地区一致。平均龋失补牙数为4.5。对于患有猖獗性龋齿的儿童组，平均龋失补牙数要高得多（11.3）。
