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.
几个世纪以来，人们都知道唾液流速与情绪状态之间存在关联。心理过程在口干主观感受中的重要性已在之前讨论过，本研究探讨的是患有特发性口干主观感受的个体中抑郁症状的存在情况。通过贝克抑郁量表（BDI）对94名健康受试者进行评估，这些受试者未刺激和刺激后的全唾液流速正常，但有口干的主观感受，并与年龄和性别匹配的健康对照组进行比较。有口干主观感受的受试者抑郁程度明显更高，抑郁症状出现的频率也显著更高。在有口干主观感受的个体中，21.3%存在抑郁，而对照组中这一比例为3.2%。本研究结果表明，在某些情况下，主观口干可能源于心理因素。
