title: Patients' perceptions of benefits and risks of complete denture therapy.
abstract: OBJECTIVE
  The aim of this study was to assess patients' perceptions of benefits and risks concerning complete denture therapy. A secondary objective was to assess the influence of clinical and sociodemographic variables on patients' perceptions.
  
  
  METHODS
  The sample was composed of 104 volunteers who presented themselves for complete denture treatment at a dental school. The average age of the volunteers was 69.2 years (±) 9.3. Patient opinions concerning the benefits of complete denture therapy were recorded using a previously reported questionnaire. The answers were evaluated in three domains: (1) benefits (positive perceptions); (2) risks (negative perceptions); and (3) consequences of no treatment.
  
  
  RESULTS
  The average time of use of the previous dentures was 20 years (SD ±12.9). Risk factors (negative perceptions) received lower scores by the patients, while the consequences of no treatment received higher scores. No association was found among evaluations of the previous dentures and educational level, marital status, and gender; however, patients' evaluation about their previous dentures was significantly different depending on age (p = 0.001) and previous dentures' time of use (p = 0.038).
  
  
  CONCLUSIONS
  Patients presented a positive perception of complete denture therapy, and the risk factors (negative perceptions) received the lowest scores. Patient perception regarding complete denture therapy was not influenced by educational level, evaluation of the previous dentures, or marital status.
