title: Association between nutrition and the prosthetic condition in edentulous elderly.
abstract: OBJECTIVE
  The aim of this study was to assess the possible risk of malnutrition among the elderly population.
  
  
  METHODS
  twenty-three pairs of complete dentures were made for a group of patients and 17 upper complete dentures with implant-supported lower dentures were made for a different group.
  
  
  METHODS
  The study was performed at the University of São Paulo--Dental Branch, Brazil. The patients were submitted to a nutritional test, as well as to a clinical examination and interview. Chewing ability and patient's satisfaction with their prostheses were evaluated. The nonparametric statistics proof of chi-squared, level 0.05 was performed and because of the low frequencies. The Fischer test was also used.
  
  
  RESULTS
  Patients wearing mandibular implant-supported dentures were considered well nourished (76.47%) when compared with complete dentures users (43.48%). There was a significant difference between the two groups, concerning to chewing ability (chi2 = 5.79) and nutritional status (chi2 = 4.35).
  
  
  CONCLUSIONS
  The risk of malnutrition was higher for elderly wearing complete dentures. The psychological state influences the interest in diet and choice of food.
