There have been several studies suggesting the overlap between specific brain regions involved in pain and taste perceptions, and the recent studies that the patients with chronic pain such as chronic back pain or fibromyalgia reported increased taste sensitivity. The aim of this study was to evaluate the gustatory function in the patient with temporomandibular disorder (TMD).Nine TMD patients with no high levels of anxiety and depression, and 17 age- and gender-matched control volunteers were evaluated. Detection and recognition thresholds for sour and umami taste, and ratings of both suprathreshold taste intensities and pleasantness-unpleasantness perceptions for sweet, sour, salty, bitter, and umami stimuli were evaluated in each subject. Graded Chronic Pain (GCP) scale, Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), and both resting and stimulated whole salivary flow rates were measured.The obtained results were as follows.1.TMD patients showed significantly lower detection thresholds and recognition thresholds for umami taste than the control subjects. 2.TMD patients showed lower stimulated salivary flow rates than control subjects.3.The GCP scales of the subjects were significantly correlated with detection thresholds of umami taste.4.The GCP scales of the subjects were significantly correlated with stimulated salivary flow rates.5.The detection thresholds for umami taste were significantly associated with the existence of TMD after adjusting the age, gender, BDI, BAI, and unstimulated salivary flow rates.Our results showed that the patients with TMD reported increased sensitivities for umami taste, and suggested the possibilities of gustatory function changes in chronic TMD patients.
