An unstimulated whole saliva flow rate in a normal person is 0.3–0.4 ml per minute, [7] and below 0.1 ml per minute is significantly abnormal. A stimulated saliva flow rate less than 0.5 ml per gland in 5 minutes or less than 1 ml per gland in 10 minutes is decreased. [1]
Saliva is an important component of the taste mechanism. Saliva both interacts with and protects the taste receptors in the mouth. [5] Saliva mediates sour and sweet tastes through bicarbonate ions and glutamate, respectively. [6] The salt taste is induced when sodium chloride levels surpass the concentration in the saliva. [6]
The main significance of the condition is a lack of saliva, causing xerostomia (dry mouth), with accompanying susceptibility to dental caries (tooth decay), infections of the mouth, [1] and upper respiratory tract infections (e.g., candidiasis, ascending sialadenitis, laryngitis and pharyngitis).

The concentration of calcium in saliva produced by the submandibular gland is twice that of the saliva produced by the parotid gland.

The submandibular duct (Wharton's duct) is long, meaning that saliva secretions must travel further before being discharged into the ...
