Fluoridation and public relations

Disczusion and conclusions In the official report on the studies (Ministry of Health, Scottish Office, Ministry of Housing and Local Government, 1962) comparison is made between the findings in Great Britain and those in the Grand Rapids study in the United States (Arnold, Dean, Jay & Knutson 1956). After adjustment for changes in the control areas, the reduction among children aged 4 years was 4276 in Grand Rapids and 5426 in Great Britain, the corresponding figures for children of 5 years being 45% and 47%. The same order of reduction was thus being achieved in this country as in Grand Rapids, and it is reasonable to expect that over a longer period of fluoridation in this country results for both the deciduous and permanent teeth similar to those in Grand Rapids will be obtained. The findings from these American and British studies themselves provide clear evidence of the value of fluoridation as a preventive measure against dental caries. In conjunction with the findings from studies in other parts of the world, they provide massive evidence.
