19
Q

neurological site of damage for stroke

A

CNS

contralateral side

20
Q

non-stroke (bell’s palsy) site of neurological damage

A

peripheral

same side (ipsilateral)

21
Q

checks for ortho appliance delivery

A
  • right pt for appliance
  • matches prescription
  • integrity of wire work
  • sharp areas
  • blanching when placed in
  • posterior retention (arrowheads, flyovers)
  • anterior retention
  • activate
  • tell-show-do
  • review 4-6 weeks
22
Q

advice for pt after delivery URA

A
  • practice speaking - read a book aloud
  • increased salivation for 24hours
  • discomfort - normal means working
  • wear 24/7
  • clean after every meal with soft toothbrush
  • remove when playing contact sports or high apiration activities
  • avoid hot or sticky foods - scald
  • non compliance increases time for tx
  • emergency contact number
23
Q

neurological action of stroke

A
  • interuption of the supranuclear fibres from the motor areas in the cerebral cortex (before they reach the facial nucleus)
  • upper facial muscles receive crossed and uncrossed fibres
  • frontalis/orbicularis oculi spared

inferior alveolar (and so mental)

lingual

long buccal

26

mandibular teeth to midline

body of mandible

buccal mucosa

anterior 2/3 tongue and floor of mouth on same side

coronoid notch

pterygomandibular raphe

retromolar pad

anterior ramus of mandible

opposite 5

28
Q

too lateral IAN placement

A

hit bone early before 2-2.5cm advancement

reposition handle distally

29
Q

too far IAN placement

A

no bone hit

reposition handle distally

30

31
Q

azoles action

A

prevent ergosterol biosynthesis via inhibition of 1,4 demihylase enzyme

32
Q

azole resistance

A
  • upregulation of efflux pumps (CDR/MDR)
  • biofilm formation
  • changes to ergosterol target enzyme
33
Q

dentally fit for cancer tx

A

free from dental disease and any possible source of infection before start cancer tx

34
Q

caries - clincal Vs radiograph appearance

A

deeper clincally than on radiograph

35
Q

composite Vs amalgam

A

aesthetics

minimal prep

bond (marginal seal adv)

similar modulus of elasticity

36
Q

impair diffusion (need mechanical removal)

antibiotics can bind to it - resistance

growth rate

RCT 4 characteristics

A

blinding

ramdomisation

comparative (control)

inclusion criteria

41
Q

reasons for lower 6s extractions

A

grossly carious

avoid caries in adj teeth

reduction of future ortho need (crowding) - spontaenous space closure

42
Q

reasons to avoid paediatric extractions

A

possible GA risk

bad dental experience - can hinder future

43

how to check practice protocol (e.g. decon)

A
  • check current legislation and compare to cuurent SOP
  • observe (audit)
    • compare findings to current legislation

determine if action required
