Function of salivary glands and sialochemistry in sialadenosis

Human sialadenosis is a non-inflammatory disease affecting the cephalic salivary glands, mainly the parotid, characterized by a mostly bilateral, painless swelling due to a substantial increase of the glandular parenchyma. After the presentation of clinical, cytological and biochemical data the probable etiology of this disease is discussed. It is concluded that sialadenosis is not a disease of the salivary glands themselves but of their sympathetic innervation.
