Nutritional adequacy of reported intake of edentulous subjects treated with new conventional or implant-supported mandibular dentures.

The nutrient content of the diet of edentulous patients who have various oral prostheses is of concern. This study compared baseline food records to those records kept semiannually for 3 years after treatment to ascertain whether nutrient intake of edentulous patients changed after they received new implant-supported mandibular dentures (n = 41) or new conventional dentures (n = 30). No significant differences in intake of calories or of 27 nutrients were noted between the two groups (p > 0.01). A decline in the percent of calories from fat with a corresponding increase in carbohydrate calories within both groups (p < 0.01) reflected a national trend; a slight decrease in calories was similarly observed (p < 0.02). More than 40% of patients in both groups were found to have inadequate intakes of dietary fiber, calcium, or both, and 25% to 50% had low intakes of vitamins A, E, D, B6 and/or magnesium. Intakes were similar to those reported for two age-matched populations.
