abstract: OBJECTIVE
  To investigate the oral health-related quality of life in patients with oral lichen planus (OLP) using the Chinese version of the oral health impact profile (OHIP)-14.
  
  
  METHODS
  51 patients with OLP were included and completed the questionnaire of OHIP-14 subsequently the REU scoring system was utilized to record the local condition and a visual analogue scale (VAS) to rate the pain they experienced. The reliability and validity were analyzed by SPSS 16.0 software.
  
  
  RESULTS
  The score of OHIP-14 was 21.67 +/- 9.45, Cronbach's alpha of the translated scale was 0.901. The items were divided into 5 domains by factor analysis. There was certain logical relation between the items in the same domain. There was highly significant association between the OHIP-14 score and REU score as well as VAS score (r=0.608, 0.807, P<0.000).
  
  
  CONCLUSIONS
  OHIP-14 performs well in patients with OLP, and have good validity and reliability.
