DENTAL CARIES IN THE COTTON EAT(10)

caries involvement of intact teeth by eliminatingthe caries in fractured cusps from the total score. Thesecorrected caries scores, given in table 1, did not alter thecaries evaluation. The diets which contained processed cerealsstill resulted in considerably more carious fissures, excludingthose in fractured cusps. Thus the extensive cariogenicityof oatmeal was shown to be a general characteristic of processed cereals. It should be pointed out that these experimentsindicate that the cariogenicity of a given diet is not contingentsolely upon the type and amount of carbohydrate used.Larson ('49) observed that Hawaiian natives eating taro(alkaline ash) generally had considerably less tooth decaythan those consuming- rice (acid ash). Therefore a furtherstudy was made of the cereal portion of t
