Dental Caries in the Cotton Rat IX. Effect of Milk Rations ∗

Abstract

Summary

Data on growth and caries indices of cotton rats fed various mill, rations were secured from these experiments

The data indicate that milk is piotective againit dental caries in the cotton rat. Previous findings of Zero scores in animals fed only liquid mill were confirmed. Animals reciving milk to which sucrose, glucose or dextri-maltose had been added exhibited low caries scores as compared with controls on a cariogenic dry ration. These sugars will producecaries when fed in dry ration. The caries indices of animals receivinq approximately one-third of their caloric intake as liquid millk and the remainder as the cariogenic ration 8.02 were less by 50% than those of litter-mate controls not receiving milk.
