Abstract
The postnatal effects of a high-sucrose, high-protein or high-fat diet on the mineral composition of the teeth of albino rats were studied by feeding these diets for a period of 150 days from weaning. The mothers of these animals had been fed only a stock diet. The prenatal effects were studied by feeding these diets to animals whose mothers had been raised on these diets and fed the same diets during pregnancy and lactation. The preponderance of any one of the major foodstuffs in the diet had neither a prenatal nor postnatal influence on the mineral composition of the teeth. The greater cariogenicity of the high-sucrose as compared with the high-fat and high-protien diets which had been demonstrated previously, can not therefore be ascribed to any changes induced in the mineral composition of the teeth by a preponderance of sucrose in the diet
