DENTAL CARIES IN THE COTTON EAT(3)

nd dextrin for the milkportion. It seemed likely that the cereal and mineral contents of our natural diet were the factors primarily concernedin its extensive cariogenicity. The consumption of processedcereals has been considered by several investigators to be animportant factor in the increased caries incidence of manypeoples who previously had been relatively caries-free (Os-born and Noriskin, '37; Stephan, '48). We wish to reportfurther studies on the caries-producing activity of processedor whole cereals when fed to cotton rats.1Published with the approval of the Director of the Wisconsin AgriculturalExperiment Station.
