title: Impact of new prostheses on the oral health related quality of life of edentulous patients.
abstract: OBJECTIVE
  A study was conducted to evaluate the impact of the placement of complete dentures by using the Global Oral Health Assessment Index (GOHAI).
  
  
  BACKGROUND
  Oral health quality of life indicators can be used to evaluate the effects of dental treatments.
  
  
  METHODS
  The 26 participants were treated in a French University Clinic during 2002. They were randomly divided into two groups. Each group received new prostheses, but evaluation of the quality of life was made at different periods [baseline, denture placement (group 1), 6 and 12 weeks (group 2) after placement]. A questionnaire was used to collect information on patient's satisfaction with the previous and new prostheses. Nonparametric tests were used to test the relationships between patients' satisfaction or baseline data and GOHAI variations with time as well as to compare mean values of GOHAI within each group.
  
  
  RESULTS
  At baseline, the impact of oral health problems was apparent; the mean GOHAI-Add score was 45.8 (10.2). Six weeks after placement of the new denture, there was no difference in GOHAI scores compared with the initial assessment. An improvement in GOHAI score was observed 12 weeks after the participants received their new dentures (p < 0.05). Change in GOHAI-Add scores was negatively correlated with the initial GOHAI-Add score. Patients who preferred the new prosthesis enjoyed a positive change in GOHAI scores (p < 0.001). There was a relationship between participants' satisfaction with the new dentures and change in GOHAI scores (p < 0.05).
  
  
  CONCLUSIONS
  The GOHAI can be used to evaluate needs for and effect of the making of new complete dentures.
