Results: There were positive correlations between oral health-related quality of life and self-reported dry mouth (functional limitationr=0.288, physical pain r=0.219, psychological discomfort r=0.193, physical disability r=0.280, psychological disability r=0.205, socialdisability r=0.224 and handicap r=0.270). In the multiple regression analysis, variation of self-reported dry mouth were positivelyassociated with dry eyes{very often(=0.305)), sometimes(=0.186)}, dryness on lips{very often(=0.247), sometimes(=0.177)},handicap(=0.152), physical disability(=0.128) and alcohol drinking(1-2 times/week)(=0.116) (p<0.001).
