Abstract
The purpose of the study was to compare the dental health of 11-year-old and 14-year-old children in three Bristol schools with that of children of the same ages who attended the same schools and participated in a clinical trial from 1970 to 1973. The children were examined by the same two clinicians who conducted the clinical trial. The results showed marked reductions in dental caries experience. The reductions of mean DMFT and DMFS of 11-year-old children from 1970 to 1979 were 36 and 41%, respectively, and of 14-year-old children from 1973 to 1979, 30 and 36%, respectively. The reason for these reductions is unknown, but it is noted that they occurred during a period when the use of toothpastes containing fluoride increased markedly.Keywords
