Fluoridation in part of Cumbria (formerly Cumberland) was started in October, 1969. The two major towns in the fluoridated sector are Workington and Cockermouth. The two nearest comparable towns in the low‐fluoride sector are Carlisle and Penrith (F=<0.1 ppm). In April and May, 1975 dental examinations were made of first year school entrants who were continuous residents in either one or the other of these communities. To obviate the possibility of bias approximately 40 per cent of the children examined were ‘decoys,’ children not meeting the criteria of age, residence or non‐receipt of fluoride tablets, topicals or sealants. Analyses of the data were carried out independently by specialists in community medicine. Caries experience in the fluoridated community (F=1 ppm) was found to be 46 per cent less than in the non‐fluoridated community. Site attack was correspondingly less by 50 per cent.
