DENTAL CARIES IN THE COTTON EAT(11)

he ration by comparing the cariogenicity of acid residue cereals with that ofalkaline residue foods when each was incorporated in a partially synthetic diet as the major source of carbohydrate. Thebasal diet for these experiments was formulated to approximate the composition of the cereal-milk diet used in the previous experiments. It consisted of 17% casein, 5% celln flour,53% floured dextrin, 18% sucrose, 2% salts IV, 5% corn oil,and adequate levels of B vitamins. The various cereals usedwere substituted for the floured dextrin of the basal diet.In order to maintain approximately equivalent levels of protein and carbohydrate, the casein level was decreased to 12%and the amount of cellu flour raised correspondingly to 10%in the experimental diets.Potatoes were used as representative of an
