Dysgeusia, burning sensations in the tongue (BST), and halitosis in patients with primary Sjögren’s syndrome and in healthy controls. Significantly higher frequencies of pSS patients with self-reported complaints of dysgeusia (χ² = 23.6, p < 0.0001), BST (χ² = 31.6, p < 0.0001), but not of halitosis (χ² = 0.40, p = 0.434) in comparison with healthy controls
