Abstract
The hypothesis of this study was that dental status significantly affects diet, nutrition and nutritional status in U.S.A. adults. The objectives were to test whether significant relationships existed between numbers of teeth, of occluding pairs of teeth (OPs) and of posterior occluding pairs of teeth (POPs) amongst (1) those with a solely natural dentition and (2) those who had a dentition with a combination of replaced and natural teeth. In addition, to test whether complete denture wearers differed from fully dentate adults in relation to diet, nutrition and nutritional status. Data were for adults 25 years and older (n=12,243) from the third U.S.A. National Health and Nutrition Examination Survey (NHANES III) 1988-1994, which used a stratified, multi-staged probability sample of the United States non institutionalized civilian population. The population had a full dental examination and dietary analysis and an assessment of blood analytes and anthropometric measures. Findings of multivariate analyses indicated that complete denture wearers had lower (1) consumption of most foods (2) dietary fibre and (3) levels of blood analytes than did the fully dentate. Significant relationships existed between numbers of teeth (and OPs and POPs) and most of the nutrition related outcomes amongst people with only natural teeth. Among people who had both natural and replaced teeth there were some differences in diet, nutrition and nutritional status between those with low numbers of teeth, OPs or POPs (whether natural or replaced) compared to fully dentate adults. On the other hand, there were few associations between diet and dental status in the rehabilitated group with more than 20 teeth. An inverse relationship was found between dental status and Body Mass Index across all typologies.
