title: Depressive symptoms in individuals with idiopathic subjective dry mouth.
abstract: It has been known for many centuries that there is a relationship between saliva flow rate and emotional status. The significance of psychological processes in the subjective sensation of a dry mouth has been discussed earlier, and this study deals with the presence of depressive symptoms in individuals with idiopathic subjective sensation of a dry mouth. Depressive symptoms in 94 healthy subjects with normal flow rates for unstimulated and stimulated whole saliva but with a subjective sensation of a dry mouth were assessed by the Beck Depression Inventory (BDI) and compared with healthy age- and gender-matched controls. The subjects with a subjective dry mouth condition were significantly more depressive and also had a significantly higher frequency of depressive symptoms. Depression was found in 21.3% of the individuals with a subjective dry mouth sensation and in 3.2% of the controls. The results of this study indicate that, in some cases, subjective dry mouth may be of psychological origin.
