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.

Vesicular Pathology

Neutrophilic Inflammation

Granulomatous and pyogranulomatous Inflammation

Eosinophilic Inflammation

Necrotizing Inflammation

Lymphocytic and plasmacytic Inflammation

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.

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