Dental status and its relationship to diet and nutritional status have been little explored. In this study of a representative sample of the US civilian, non-institutionalized population (NHANES III), we predicted that the intake of nutritious foods, dietary fiber, and levels of biochemical analytes would be lower, even after adjusting for potential social and behavioral factors, among those who were edentulous and wore complete dentures than for those who had all their natural teeth. Multivariate analyses indicated that intake of carrots and tossed salads among denture-wearers was, respectively, 2.1 and 1.5 times less than for the fully dentate (p < 0.0001), and dietary fiber intake was 1.2 times less (p < 0.05). Serum levels of beta carotene (9.8 microg/dL), folate (4.7 ng/dL), and vitamin C (0.87 mg/dL) were also lower among denture-wearers (p < 0.05). Intakes of some nutrient-rich foods and beta carotene, folate, and vitamin C serum levels were significantly lower in denture-wearers.
