title: Edentulous patients' knowledge of dental hygiene and care of prostheses.
abstract: OBJECTIVE
  The aim of this study was to analyse denture users' oral care habits with regard to the use of their prostheses.
  
  
  BACKGROUND
  Rehabilitative treatment is only successful when patients are motivated and aware of correct prosthesis use and hygiene.
  
  
  METHODS
  Questionnaires were distributed to 150 complete denture users at the Federal University of Bahia School of Dentistry, the Esmeralda Natividade Health Center, the Bahian Science Development Foundation and a Salvador nursing home. The questionnaire included information on gender, age, length of prosthesis use, cleaning methods and materials, etc. The data were analysed using EpiInfo version 6 software. The chi-squared test was used for statistical analysis, with a significance level of 5%.
  
  
  RESULTS
  Questionnaire results showed that 78% of the subjects, with an average age of 67.3 years, had used the same complete denture for over 5 years. 64% slept with their prostheses and 44% removed them from the mouth only for cleaning. None of the patients interviewed knew anything about brushes designed specifically for complete dentures. 37.3% had a restricted diet and 44% believed that a complete denture would last for more than 10 years.
  
  
  CONCLUSIONS
  Within the limitations of this study, it was concluded that the edentulous patients surveyed had limited awareness of prosthetic hygiene and long-term oral care despite extended periods of denture use.
