Test 1

Question 1

1. Reactionary Dentine

Answer 1

Repairs minor damage (secondary dentine

Question 2

2. Reparative dentine

Answer 2

Repairs major damage (tertiary dentine)

Question 3

3. A delta fibers (dentinal pain)

Answer 3

• large myelinated afferent nerve(peripheral) (coronal)

- initial sharp pain , associated with cold temp

Question 4

4. C fibers (pulpitis pain)

Answer 4

• small, unmyelinated afferent
• centrally/stromal
• dull, throbbing and longer pain
• IRP, heat associated

Question 5

5. Hyperalgesia and allodynia

Answer 5

Hyperalgesia: heightened response to pain
-inflammatory mediators increasing stimulus

Allodonia: reduced pain threshold, pain die to stimulus that does not normally provoke pain
E.g white people sunburn

Question 6

6. Reversible pulpitis: EPT, radiographic, pain

Answer 6

• tooth with carries presents with less current
• Radiolucency with no pulpal involvement
• mild (seconds) on stimulation, no referred pain,

Question 7

7. Irreversible pulpitis EPT, radiographic, pain

Answer 7

• tooth with carries present with more current
• Radiolucency, involve pulp
• severe and lingering on stimulation, referred pain, spontaneous and increase at night

Question 8

8. Pulp necrosis EPT, radiographic, pain

Answer 8

• no sensation even at high reading
• carries in dentine involve pulp
• no pain!

Question 9

9. EPT

Answer 9

• least reliable

indicates vital sensory fibres but not vascular supply to pulp ( which is the true determinant of pulp vitality)

Question 10

10. Pulp; age

Answer 10

• younger patients have better prognosis with pulp capping
• as the pulp ages, it gets more calcified and fibrotic and decreases in vascularity
• older patients experience less pain, less nerve supply

Question 11

11. fibre-optic light

Answer 11

transillumination to check for fractures, enamel cracks interproximal carries, opacity and discolouration
