what does paralysis of lower face indicate?
upper motor neurone (contralateral side)
e.g. stroke, cerebral tumour, trauma
what does paralysis of complete side of face indicate?
lower motor neurone (ipsilateral side)
e.g. bells palsy, parotid tumour, misplaced IDB, trauma
describing a lump/swelling
site shape size single/multiple texture warmth tenderness fluctuation sensation/pulsation
describing an ulcer
site shape size single/multple base edge pain time
suspicious findings of an ulcer
rolled edges firm/hard/attached necrotic friable tissue in base bleeding on light pressure painless in early stages
where are minor aphthae ulcers located
lining mucosa - not hard palate/gingiva
2 main purposes of microbiology in dentristry
diagnosis
so can treat with best pharmocotherapeutic agents
added technique for FNA
ultrasound used to guide
disadvantage of fine needle aspiration
infection afterwards - usually only used for suspicious lesions
normal size for incisional biopsy of ulcer
10mmx10mm - must include border + sound tissue
what tissues does CBCT pick up?
hard tissue
indications for ultrasound use
lymph nodes
salivary glands
contraindication for MRI scan
fixed metal appliances/implants e.g. pacemaker
3 conditions at increased risk of infective endo
prosthetic valve
previous IE
cyanotic CHD
dose for IE prophylaxis
amoxicillin 3g 60 mins before
or
clindamycin 600mg 60mins before
dental relevance of hypertension
increased stoke/MI risk
should be managed before GA
local anaesthetic adrenaline - aspiration important to reduce intravascular risk
leading cardiac cause of stroke
atrial fibrillation
which common medications should not be prescribed to patient with asthma?
NSAIDs
may be allergic
why should NSAIDs be avoided in leukaemia?
increased risk of gastrointestinal bleeding
3 step to haemostasis
vessel constriction
platelet plug
coagulation cascade
what LA should be avoided in pts with increased risk of bleeding?
IDB
safe level for platelet count before invasive dental treatment
50x10^9 /l
lower would require platelet diffusion
pre-op treatment for haemophilia A
mild = DDAVP infusion - VIII + vWF severe = VIII/IX replacement
pre-op treatment for haemophilia B
IX infusion
