Care of the pulp

Question 1

vital tissue

Answer 1

responds to stimuli and has regenerative potential

Question 2

endodontics

Answer 2

in relation to the pulp

Question 3

RDT

Answer 3

remaining dentine thickness

Question 4

what fibres are most likely to transmit a sharp pain in the pulp

Answer 4

alpha fibres

Question 5

what fibres are most likely to transmit a dull pain in the pulp

Answer 5

c fibres

Question 6

how do reversible and irreversible pulpitis differ

Answer 6

they differ in their clinical signs and symptoms

both sees a vital inflamed pulp however irreversible is inflamed beyond repair

Question 7

signs and symptoms of reversible pulpitis

Answer 7

no change to pulp blood flow , pain to cold stimuli, hydrodynamic expression
response to sensibility tests

Question 8

hydrodynamic mechanism

Answer 8

activates intradental sensory nerves
increased dentinal fluid flow sees intradental nerves being activated ad generating an AP and passing it to the brain as pain

Question 9

signs and symptoms of irreversible pulpitis

Answer 9

spontaneous pain. , disturbance to sleep, pain to hot stimuli, increased pulp blood flow

Question 10

necrotic pulp

Answer 10

non vital , partial or total necrosis

Question 11

what are sensibility tests used for

Answer 11

to distinguish between a vital and non vital pulp
these tests relate to nerve supply not blood flow which is the real indicator of vitality so don’t always give the full story/ entirely accurate

Question 12

electric pulp test

Answer 12

stimulates alpha fibres at dentine- pulp junction
