beta-carotene and Tooth-Loss

The aim of this study was to investigate the effects of a counselling-based dietary intervention on nutritional status in partially dentate patients receiving removable partial dentures (RPDs). Thirty-eight patients [mean age (standard deviation): 73.2 (7.7) years] who were scheduled to receive RPDs at a dental hospital and were currently eating <350 g of vegetables per day were included in the study. A dentist provided basic dietary counselling aimed at increasing dietary fruit and vegetable intake and improving dietary habits. Patients received dietary counselling directly after treatment with new RPDs and at 1 week after a 1-month follow-up evaluation (T1). Food intake was assessed via a validated brief-type self-administered diet history questionnaire, and carotenoids and vitamin C in 6-hour fasting blood samples were measured before RPD administration, and at 1 (T1) and 3 months (T3) thereafter. Vegetable but not the fruit intake increased significantly at T1 and T3 compared to before treatment. Alpha carotene significantly increased at T3 while β significantly increased both at T1 and T3 compared to before treatment (P < .05). The number of occlusal units on natural teeth was significantly positively associated with increased vegetable and β-carotene intake (P < .05). Serum carotenoids and vitamin C levels measured with 6-hour fasting blood samples remained constant. These results suggest that basic dietary counselling may improve vegetable intake in partially dentate patients receiving RPD treatment, but did not lead to haematological changes. The presence of occlusion of remaining posterior teeth may be critical for improving vegetable intake.

To examine the relationship between the number and type of teeth and nutrient intakes in adults, aged 60 years and above, in the National Health and Nutrition Examination Survey 1999-2004 using linear regression.. Four discrete dental status groups were created: complete natural dentition (reference group), incomplete natural dentition, complete mixed (natural and restored) dentition and incomplete mixed dentition. We ran both unadjusted and adjusted models, controlling for age, race/ethnicity, education and smoking status to examine the effect of these covariates on the association between dentition status and nutrient intakes. Separate models were run for men and women.. There were significant associations between dental status and all the examined nutrients for men and for the carotenes and folate for women in the unadjusted model. Only caloric and vitamin C intakes were significant for men, and β-carotene was significant for women in the adjusted model. For men for kilocalories and women for β-carotene, those with a complete dentition had higher mean intakes than those with an incomplete dentition, regardless of the tooth type. Among men with an incomplete dentition, those with a mixed dentition had a significantly lower vitamin C intake than those with a natural dentition; there were no significant differences between the natural and mixed complete dentition groups.. Demographic and behavioural variables explained many of the differences seen in nutrient intakes. After controlling for these variables, we found that a numeric threshold of teeth (i.e. a functional dentition) influenced some nutrient intakes while the number and type of teeth present affected other nutrient intakes.

Evidence that dental status affects diet is equivocal. The hypothesis of this study was that diet was affected by dental status. The objective was to assess the relationship between numbers of teeth and diet and nutritional status in US adult civilians without prostheses. We examined 6985 NHANES (1988-1994) participants. Data included socio-economics, demographics, dental status, and diet and nutritional status. Dietary data were obtained from food frequency questionnaires and 24-hour dietary recall. Serum levels of beta carotene, folate, and vitamin C were measured with isocratic high-performance liquid chromatography. The population was classified by numbers of teeth. Covariance and Satterthwaite F-adjusted statistical comparisons were made between tooth groupings and the fully dentate population. Multilinear regression models adjusted for covariates. People with fewer than 28 teeth had significantly lower intakes of carrots, tossed salads, and dietary fiber than did fully dentate people, and lower serum levels for beta carotene, folate, and vitamin C. Dental status significantly affects diet and nutrition.

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.
