Problems with Salivation Flashcards
what do you examine intra-orally for examining salivary glands
minor salivary glands
duct orifices
fluid expression
what are the functions of saliva
acid buffering
mucosal lubrication
taste facilitation
antibacterial
what can cause a dry mouth
salivary gland disease
drugs
medical conditions
radiotherapy and cancer treatments
anxiety and somatisation
what is lost in salivary glands as a normal process of aging
acinar tissue loss
what anti-muscarinic cholinergic drugs can cause indirect salivary problems
tricyclic antidepressants
antipsychotics
anithistamine
atropine
diuretics
cytotoxics
what are chronic medical problems associated with dry mouth
diabetes
renal disease
stroke
addisons disease
persisting vomiting
what acute medical problems are associated with dry mouth
acute oral mucosal diseases
burns
vesiculobullous diseases
haemorrhage
what are some direct salivary gland problems
aplasia
sarcoidosis
HIV
gland infiltration
cystic fibrosis
what is ectodermal dysplasia
hair, nails, teeth and salivary glands all aplastic and deficient
what is sarcoidosis
granuloma change in salivary glands causing enlargement of parotid and submandibular glands
how does HIV affect salivary glands
causes lymphoproliferative changes in the gland where it increases in bulk but decreases in function
what is amyloidosis
deposition of protein in the gland which prevents the gland from working properly
what is haemochromatosis
excess storage of iron within tissue which stops salivary tissue from functioning
what is the effect of radiation on the glands
blood supply lost to gland
what is the effect of radioiodine on the glands
iodine accumulates in glands and kills of acinar cells affecting salivary function
