BOWES, ANNA DEP. : School of Dentistry, University of Pennsylvania, Phila­delphia, Pa. (Apr. 18, 1939).

In a study of the relation of diet to dental conditions, the greatest devia­tions from adequate diets occurred in prenatal, adolescent and adult periodontia groups, in both (dental-school) clinic and private practice. In these patients, caries and gum conditions were also more serious. The diets of the perio­dontia patients, in both groups, were much more deficient in calcium, phos­phorus, vitamin C and alkaline-ash foods than the diets of the other adult groups. The diets of the control patients, who were free from caries, were excellent and above normal requirements in practically all dietary essentials.

Dietary analyses, made from a week’s record for 312 (dental-school) clinic and 89 private patients ranging in age from 3 to 65 years, showed that no diet in either group was adequate in all essentials. The greatest number of deficiencies or deviations from desirable standards occurred in the carbohydrate-fat ratio, iron, and vitamins D and B. A study of dietary essentials most closely related to teeth showed that, in the (dental-school) clinic adult patients (189 cases), 52% of the diets were deficient in calcium, 65% in phosphorus, 52% in vitamin A, 30% in vitamin C, 93% in vitamin D; 22% had an excess of acid-forming foods. In the clinic children’s diets (123 cases), 61% were deficient in calcium, 30% in phos­phorus, 62% in vitamin A, 49% in vitamin C, 88% in vitamin D; 22% had an excess of acid-forming foods. In the private-office adult group (72 cases), 78% of the diets were deficient in calcium, 88% in phosphorus, 51% in vitamin A, 28% in vitamin C, 96% in vitamin D; 15% had an excess of acid-forming foods. In the private-office children’s group (17 cases), 41% of the diets were deficient in calcium, 12% in phosphorus, 59% in vitamin A, 24% in vitamin C, 94% in vitamin D; 12% had an excess of acid-forming foods.
