Diagnosis

Question 1

tests

Answer 1

ept
ethyl chloride
test drilling

Question 2

how do sensibility tests work

Answer 2

test neuron/nerve function response
MEASURES RESPONSE TO STIMULI APPLIED TO NERVE FIBRES

Question 3

what are the issues

Answer 3

don’t stimulate nerve fibres themselves
doesn’t correlate to blood supply

VITALITY RELATED TO BLOOD SUPPLY, NOT NERVE STIMULATION
would need laser doppler

Question 4

describe electric pulp test

Answer 4

electric current used to stimulate nerves at the pulp-dentine junction
stimulates A delta fibres

Question 5

electric pulp test procedure

Answer 5

dry, isolate
conduction medium on tip
incise edge or cusp tip adjacent to pulp horn
pt completes circuit by holding handle, release on tingling/heat

Question 6

average and meaning of EPT response

Answer 6

0-80, incisor 10-40, molar 20-55

very quick indicates inflammation
no response indicates necrosis

Question 7

describe function of thermal tests

Answer 7

tests hydrodynamic forces, fluid movement in dentine tubules
activates pulp sensory nerve receptor units

Question 8

describe cold test procedure

Answer 8

endofrost/ethyl chloride

dry, isolate, cotton wool
negative = necrosis

Question 9

describe heat test procedure

Answer 9

caution as may cause IP

initial a delta stimulation [sharp pain]
continued to C fibre activation [dull, radiating pain]

vaseline, hot GP/greenstick
negative = necrosis

Question 10

describe test drilling

Answer 10

used for full coverage restorations
no LA, drill into tooth

generally not done, cruel and evil
