Changes In Rat Incisor Teeth In Response To Dietary Deficiencies Of Calcium Or Phosphorus In Presence And Absence Of Added Vitamin D

The greatest reduction in the mass of rat incisor tooth formed was caused by the consumption of a diet deficient in both calcium and vitamin D; this diet also had a profound effect in reducing bone mass. A simple dietary deficiency of calcium had a much smaller effect on tooth mass but affected the bone severely. Deficiency of vitamin D per se had little effect on the weight of bone and tooth formed.
