The aim of the present report was to analyze sugar consumption in relation to dental caries in Sweden from 1960 to 1985. Sugar consumption is based on official statistics from the National Swedish Agricultural Board and is expressed in grams per person and day. Over this quarter-century total sugar consumption decreased approximately 5%, from 116 to 110 g/person/day. A shift occurred from direct consumption to indirect (sugar used by the food industry), the former decreasing from 76 to 50 and the latter rising from 40 to 60 g/person/day. Available epidemiologic data on dental caries in children from the National Swedish Board of Health and Welfare indicate that the frequency of caries decreased dramatically from 1960 to 1985, though comparable data were difficult to obtain for the whole 25-yr period. The conclusion from this study is that these changes in caries prevalence in Sweden cannot be attributed to a corresponding decrease in the per capita consumption of sugar and sugar-containing products. On the contrary, the intake of some products traditionally related to dental caries, such as candy and soft drinks, increased during 1960-1985.
