Introduction
- Painful conditions in the mouth lead to increase in salivary secretion and possibly also to failure to swallow the saliva produced,
- e.g. in foot and mouth disease in cattle there is an acute painful stomatitis and this is accompanied by the hypersalivation and partial anorexia.

Sjorgren’s-like syndrome
- Xerophthalmia and xerostomia due to lymphocyte-mediated destruction of exocrine glands of salivary glands.
- Both those terms refer to cessation of production of tear or saliva production respectively.
- May be primary autoimmune or part of another autoimmune condition.
- Causes of xerostomia:
- Dysautonomia
- Infectious sialadenitis
- Neoplasia
- Salivary amyloidosis
- Head and neck radiation
- Drugs
- AutoI disease.

Hyperplastic
Sialadenosis
- Bilateral, uniform, painless, non-inflammatory enlargement of the salivary glands
- C/s of retching/gulping
- No significant histological abnormalities in the salivary gland biopsies.
