title: Association between oral health-related and general health-related quality of life in subjects attending dental offices in Germany.
abstract: OBJECTIVE
  To evaluate the GHRQoL and OHRQoL of patients attending dental offices in Germany and to determine correlation coefficients between SF (Short Form)-12 and OHIP (Oral Health Impact Profile)-14 scores.
  
  
  METHODS
  A total of 10,342 dental offices were randomly selected. Each of the 1,113 that consented to participate received 20 questionnaires to be filled in by a convenience sample of the patients. The questionnaire included the OHIP-14-form for OHRQoL as well as the SF-12-form for GHRQoL.
  
  
  RESULTS
  A total of 12,392 completed questionnaires were analyzed. The mean age of the participants (64.9 percent female, 35.1 percent male) was 44.25 years. The mean summary score of OHIP-14 was 6.30 (SD 7.46). The mean physical component summary scale (PCS) of the SF-12 was 51.15 (SD 7.23) and the mental component summary scale (MCS) was 50.17 (SD 8.55). The variance of PCS and MCS could be explained to 10 percent each by oral health-related quality of life (r2 = 0.095 and 0.101, P < 0.001).
  
  
  CONCLUSIONS
  OHRQoL is considerably related to GHRQoL.
