1. pathophysiology of salivary disorders

salivary disorders can significantly impact oral health and overall quality of life

• xerostomia (dry mouth)

• sialorrhea (excessive saliva production)

• sialolithiasis (salivary gland stones)

xerostomia

• caused by reduced/absent saliva production as the result from

• medications (anticholinergics/antihistamines)

• systematic disease (sjogren’s syndrome/diabetes)

• radiation therapy

• aging

saliva is essential for

• oral lubrication

• digestion

• antimicrobial defence

a reduction in saliva can lead to

• difficulties swallowing

• speaking

• dental caries

• oral infection

sialorrhea

results from overproduction of saliva or poor oral clearance

sialorrhea is often seen in neurological disorders

• parkinson’s disease

• cerebral palsy

• after a stroke

sialorrhea can lead to

• drooling

• aspiration

• social embarrassment

sialolithiasis

formation of calcified stones within the salivary ducts,

usually the submandibular gland which blocks saliva flow causing

• pain

• swelling

• potentially infection
