title: Demographic factors, denture status and oral health-related quality of life.
abstract: OBJECTIVE
  This study investigated the association between denture status, demographic factors, and oral health-related quality of life (OHRQoL).
  
  
  METHODS
  OHRQoL was measured using the German version of the Oral Health Impact Profile (OHIP-G, 53 items), which was administered in a personal interview to 2050 subjects (60% of eligible subjects responded) 16-79 years of age in a national survey. Median regression was used to analyze the influence of denture status (no, removable, complete dentures), age, gender, education (less than 10 years of schooling, 10-12 years, more than 12 years), and residential area (rural, urban) on the OHIP-G summary score.
  
  
  RESULTS
  In bivariable analyses, compared to the base category, the OHIP-G median increased 8.0 U for subjects with removable dentures, 20.0 U for subjects with complete dentures, 1.7 U for each 10-year age period, 2.0 U for men, 3.0 U for less than 10 years of schooling (compared to > or =10 years.), and 1.0 U for urban areas (P < 0.05 for all effects except for residential area). In the multivariable analysis, compared to subjects without dentures, subjects with removable dentures had a 7.5 (95% CI: 5.2-9.8) higher OHIP-G median and subjects with complete dentures had a 18.5 (95% CI: 14.7-22.4) higher median when demographic variables were controlled. No demographic variables were statistically significant except for residential area (P = 0.04).
  
  
  CONCLUSIONS
  Denture status was a stronger predictor for impaired OHRQoL than demographic variables and rendered age and education almost negligible in their influence on OHRQoL.
