The answer is: B

 

3- Nonspecilic biochemical mediators are :

The answer is: C

 

6- Maxillary sinusitis associated with acute tooth pain

  1. is a seasonal phenomenon.
  2. can involve the entire quadrant up to the midline.
  3. can involve the mandible.
  4. is initiated by psychogenic factors.

 

 

 

 

 

The answer is: B

 

 

7- Pain is most commonly referred from:

  1. lower anterior teeth to ipsilatcral upper molars.
  2. lower molars to upper anteriors.
  3. posterior molars to the opposing quadrant or to other teeth in same quadrant.
  4. upper molars to the contralateral lower quadrant

 

 

 

 

 

 

The answer is: C

 

8- Odontogenic symptoms are elicited primarily by the following provoking stimuli:

  1. thermal (heat, cold), percussion, palpation.
  2. postural changes.
  3. pain following exertion.
  4. barometric changes.

 

 

 

 

 

 

The answer is: A

 

9- In the presence of an intense inflammatory process, nerve block injections are rendered less effective owing to:

  1. distance to source of irritation.
  2. pH changes of inflammation.
  3. length of needle.
  4. prior use of analgesics.

 

 

 

 

 

The answer is: B

 

 

10- For effective urgent care management of the routine endodontic emergency:

  1. leave the pulp chamber open for drainage.
  2. pulpotomy will suffice.
  3. after pulpectomy, close the pulp chamber with a temporary dressing.
  4. incise with a scalpel.

 

 

 

 

 

 

The answer is: C

 

11- Localized swelling as an extension of pulpal disease:

  1. requires antibiotic therapy alone.
  2. requires analgesics.
  3. is managed using incision, drainage, and an indwelling drain.
  4. resolves without treatment.

 

 

 

 

 

 

 

The answer is: C

 

12- Flare-ups occur more often:

  1. in the afternoon and evening.
  2. in endodontic treatment of vital teeth.
  3. in endodontic treatment of pulpless teeth.
  4. in teenagers.

 

 

 

 

 

 

The answer is: C

 

13- To assess pain intensity, the most useful measure is:

  1. how much analgesia the patient requires.
  2. how well the patient eats and sleeps.
  3. zero to ten verbal analogue scale.
  4. the patient's own words.

 

 

 

 

 

 

The answer is: C

 

14- Pain can most frequently be expected as a result of:

  1. Pulpitis
  2. A nonvital tooth.
  3. An over instrumented root canal system.
  4. After routine endodontic therapy.

 

 

 

 

 

 

The answer is: C
