BY the time that Brantford, Ontario, began to fluoridate its water supply in 1945 a great deal of information had been obtained from various parts of the word concerning the effect of naturally fluoridated water on dental caries. This information showed that the incidence of tooth decay is greatly reduced in populations consuming from birth naturally fluoridated water at a level of about one part per million. No ill effects at this level were observed. We therefore wished to det

ALBERTA lags behind most of the other provinces in Canada in instituting fluoridation as a public health measure for preventing tooth decay although the University of Alberta was the first institution in Canada to carry out significant research on this subject. The discovery that fluorine in water could prevent dental caries was first made in 1931 by research workers in the United States and as early as 1935 the travelling public health clinic in Alberta reported opaque white

Abstract
Background
One of the main arguments made in favor of community water fluoridation is that it is equitable in its impact on dental caries (i.e., helps to offset inequities in dental caries). Although an equitable effect of fluoridation has been demonstrated in cross-sectional studies, it has not been studied in the context of cessation of community water fluoridation (CWF). The objective of this study was to compare the socio-economic patterns of chil

On June 20th, 1955, Brantford completed ten years of experience with mechanically fluoridated water.
Earlier reports (1) have shown that the full decay-preventing effect of the fluoridated water on the permanent dentition of the Brantford children began to show itself in 1951, when the first permanent molars appeared in the mouths of the children born there in 1945. In 1953, after these teeth had been exposed in the mouths of the eight-year-old children for a period of two years out r
