Experimental dental caries in golden hamsters—IX: The effect of a cariogenic diet fed at intervals

Abstract The influence on the caries incidence of different ways of feeding a cariogenic diet to hamsters was studied. In four preliminary experiments the following observations were made. The animals did not eat sufficient for normal growth if the food was supplied only at three half-hour mealtimes each day. A cariogenic diet containing 62 per cent sucrose did not cause any carious lesions if it was fed at three meals a day and during the weekend period or for 3 days a week either every second day or on three consecutive days. If it was given every day it had a marked cariogenic effect. When the amount of sucrose consumed during these 3 days a week was distributed over the whole week, by feeding a diet containing 26 per cent sucrose, a significant amount of caries developed.

The Effect of an Artifical ‘Bone Meal’ and its Components on Caries Incidence in the Golden Hamster

In an attempt to find out which substance or substances are responsible for the caries-reducing effeet of bone meal in hamsters a preliminary study was made with a mixture of minerals simulating the c
