mock questions

Question 1

ATLS

Answer 1

advanced trauma life support

Question 2

3 signs of a midface fracture

Answer 2

infraorbital numbness without blow to nerve
midface mobility
epistaxis without blow to nose

Question 3

adjuncts to bleeding in midface trauma (hospital setting)

Answer 3

epistat (bilateral nasal catheter)
tranexamic acid
vitamin K

Question 4

2 treatment options for facial fractures

Answer 4

open reduction and internal fixation
closed reduction and fixation (reduced via palpation and vision, fixation is external e.g cast)

Question 5

host modulation therapy as an adjunct to periotreatment

Answer 5

may be used in step 3, not recommended by SDCEP
low dose doxycycline over a long period of time

Question 6

3 bacteria in periodontal disease

Answer 6

porphyromonas gingivalis
tanerella forsythia
prevotella intermedia

Question 7

treatment of periodontal abscess

Answer 7

assess prognosis of tooth - if hopeless - extract
incision and drainage of swelling and irrigation of saline
debridement of pocket just short of base
CHX 2% if too painful to brush

Question 8

3 stages in clot formation

Answer 8

vasoconstriction
platelet plug
activation of coagulation cascade

Question 9

name 3 signs of periodontal treatment success

Answer 9

decreasing in pocket probing depths
increase in clinical connective tissue attachment
bleeding on probing from base of pocket reduced or resolved
decreased mobility

Question 10

mucostatic vs mucocompressive impression

Answer 10

mucostatic = mucosa in resting state - good retention at rest but poorer during function e.g light body silicone
mucocompressive - denture bearing area subject to compressive force - maximally stable during function but not at rest e.g impression compound, alginate

Question 11

what movement does the upper and lower joint cavity allow

Answer 11

upper - translation
lower - rotation

Question 12

function of desmopressin

Answer 12

stimulates factor VIII production, may be used prior to treating haemophilia A or VWB patients

Question 13

graft vs flap

Answer 13

graft - transferred from one site to another by complete separation, requires new ingrowth of blood vessels
flap - own blood supply, may be ‘free’ meaning they have to be ‘replumbed’

Question 14

actinic cheilitis

Answer 14

pre cancerous lesion commonly seen on lower lip

Question 15

histopathologically , what are brown tumours of hyperthyroidism identical too

Answer 15

giant cell granulomas
blood chemistry tests can tell apart (altered in hyperparathyroidism normal in giant cell)

Question 16

name one molecular biological technique

Answer 16

PCR

Question 17

immunohistochemistry

Answer 17

visualisation of specific antigens within a tissue using fluorescent microscope e.g DIF and IIF

Question 18

deterministic vs stochastic effects of radiation

Answer 18

determine - only at high doses, effects related to dose (somatic effects)
stochastic - no minimum threshold, can ake years to show, either somatic (individual who had radiation) or somatic (genetic)
