2nd Premolar- 1 (75%) or 2 (24%)/3
1st Molar- 3 (93%) or 4
2nd Molar- 3 (63%) or 4
How any roots do mandibular teeth? - ACCURATE ANSWERS✔✔
Central & lateral- 1 (58%) or 2
Canines- 1 (94%) or 2
1st Premolar- 1 (73%) or 2
2nd Premolar- 1 (85%) or 2
1st Molar- 3 (67%) or 4
2nd Molar- 3 (79%) or 2(13%)/4
Explain in brief the hydrodynamic theory? - ACCURATE
ANSWERS✔✔ Generation of movement of tubular fluid leads to
activation of the mechanoreceptors in the nerve fibres of the superficial
pulp. This in turn results in activation of the nerve fibres?
,Which nerve fibres are responsible for sharp pain of short duration? -
ACCURATE ANSWERS✔✔ A-beta and A-delta
Which nerve fibres are responsible for dull, throbbing pain or long
duration? - ACCURATE ANSWERS✔✔ C-fibres
What makes biofilms resistant to antimicrobials? - ACCURATE
ANSWERS✔✔ - May fail to penetrate beyond the surface layers of the
biofilm
- May be trapped and destroyed by enzymes
- May not be active against non-growing micro-organisms
- expression of biofilm-specific resistance genes
- stress response to hostile environmental conditions (over expression of
antimicrobial destroying enzymes)
What are the two main clinical objectives or root canal treatment? -
ACCURATE ANSWERS✔✔ 1. Removing canal contents
2. Eliminating infection
What are the three main design objective in RCT? - ACCURATE
ANSWERS✔✔ 1. Create a continuously tapering funnel shape
2. Maintain apical foramen in original position
3. keep apical opening as small as possible
,What are the uses/advantages of dental dam in RCT? - ACCURATE
ANSWERS✔✔ - Prevents contamination
- Airway protection
- Allows use of toxic disinfectants
- Improve vision and access
How can you describe pain? - ACCURATE ANSWERS✔✔ An
unpleasant feeling often caused by intense/damaging or potentially
intense/damaging stimuli
What are the three branches of the trigeminal nerve? - ACCURATE
ANSWERS✔✔ Ophthalmic, mandibular, maxillary
What is the average life of an endodontically treated tooth? -
ACCURATE ANSWERS✔✔ 7-10 years
What might spontaneous pain be a sign of? - ACCURATE
ANSWERS✔✔ Irreversible pulpitis
What might pain cause sleep deprivation be a sign of? - ACCURATE
ANSWERS✔✔ Irreversible pulpitis
What might a lack of response to pain killers be a sign of? -
ACCURATE ANSWERS✔✔ Irreversible pulpitis
, Define referred pain? - ACCURATE ANSWERS✔✔ The perception of
pain on one part of the body that is distant to the source of the pain
Where might posterior teeth refer pain to? - ACCURATE
ANSWERS✔✔ Opposite arch or peri-auricular area (more common in
mandible) but always on ipsilateral side
What should be taken note of when preforming intra-oral exam of
endodontically involved tooth? - ACCURATE ANSWERS✔✔ 1. Intra-
oral swelling
2. Sinus
3. TTPalpation
4. Percussion notes
5. Mobility
6. Perio exam
How do hot and cold tests work? - ACCURATE ANSWERS✔✔ Utilise
hydrodynamic theory to check if response to hot or cold stimuli
Which fibres are mainly stimulated in an EPT? - ACCURATE
ANSWERS✔✔ A-delta fibres (fast conducting) (c fibres may or may
not be stimulated)
Explain steps in carrying out EPT? - ACCURATE ANSWERS✔✔ 1.
Dry and isolate teeth
2. Use conducting medium (e.g. toothpaste)
