Non-neoplastic salivary gland diseases

A wide range of non neoplastic disorders can affect the salivary glands, although the more common are: mumps, acute suppurative sialadenitis, Sjögren's syndrome and drug-induced xerostomia. Salivary dysfunction is not a normal consequence of old age, and can be due to systemic diseases, medications or head and neck radiotherapy. Diagnosis of salivary disorders begins with a careful medical history, followed by a cautious examination. While complaints of xerostomia may be indicative of a salivary gland disorder, salivary diseases can present without symptoms. Therefore, routine examination of salivary function must be part of any head, neck, and oral examination. Health-care professionals can play a vital role in identifying patients at risk for developing salivary dysfunction, and should provide appropriate preventive and interventive techniques that will help to preserving a person's health, function, and quality of life. The present work provides an overview of most of the non neoplastic disorders of the salivary glands, in which the general presentation, pathology, and treatments are discussed.
