MCQs in Endodontics

Chapter 1: Diagnosis


1 - A cold test best localizes:

 

  1. pain of pulpal origin.
  2. periodontal pain.
  3. pulp necrosis.
  4. referred pain.

 

 

 

 

 

The answer is: A

 

 

2 - Anaesthetic testing is most effective in localizing pain:

  1. To a specific tooth.
  2. To the mandible or maxilla.
  3. Across the midline of the face.
  4. To a posterior tooth.

 

 

 

 

 

The answer is: B

 

3- Regarding dental history taking :

  1. Is less important than x-ray examination.
  2. Has as its principal goal to identify the offending tooth.
  3. Principally assesses intensity of pain.
  4. Focuses heavily on the quality of pain.

 

 

 

 

 

The answer is: B

 

 

 

4- Percussion testing:

  1. Differentiates pain of periodontal origin.
  2. Stimulates proprioceptive fibers in the periodontal ligament.
  3. Indicates tooth fracture.
  4. Must be performed with a blunt instrument.

 

 

 

 

 

The answer is: B

 

5- Areas of rarefaction are evident on x-ray examination when:

  1. The tooth is responsive to cold.
  2. The tooth is responsive to heat.
  3. A tooth fracture has been identified.
  4. The cortical layer of bone has been eroded.

 

 

 

 

 

The answer is: D

 

6- An area of rarefaction in the lower premolar area indicates:

  1. Definite pathology.
  2. Torus mandibularis.
  3. Possible mental foramen.
  4. Root fracture.

 

 

 

 

 

The answer is: C

 

7- Percussion, palpation, and thermal testing:

  1. Are not to be performed on patients with pacemakers.
  2. Should involve testing of contralateral teeth for comparison.
  3. Are best compared when using ipsilateral teeth.
  4. Obviate radiographs.

 

 

 

 

 

The answer is: B

 

8- Irreversible pulpitis is often defined by:

  1. A moderate response to percussion.
  2. A strong painful response to cold that lingers.
  3. A strong painful response to cold.
  4. A response to heat.

 

 

 

 

 

The answer is: B

 

9- Medical history of heart disease is significant:

  1. And contraindicates endodontic treatment.
  2. For referred pain to the left mandible indicating possible myocardial infarction.
  3. And indicates the need for premedication with antibiotics.
  4. And contraindicates local anaesthetic with epinephrine.

 

 

 

 

 

The answer is: B

 

 

10- The best approach for diagnosis of odontogenic pain is:

  1. X-ray examination.
  2. Percussion.
  3. Visual examination.
  4. A step-by-step sequenced examination and testing approach following the same procedure.

 

 

 

 

 

The answer is: D

 

11- Calcification of the pulp:

  1. Is a response to aging.
  2. Does not relate to the periodontal condition.
  3. Precedes internal resorption.
  4. Indicates the presence of additional canals.

 

 

 

 

 

 

The answer is: A

 

12- Electric pulp tests should not be performed on patients who have a :

  1. Hearing aid.
  2. Hip implant.
  3. Dental implant.
  4. Pacemaker.

 

 

 

 

 

The answer is: D

 

13- A false-negative response to the pulp tester may occur:

  1. Primarily in anterior teeth.
  2. In a patient heavily premedicated with analgesics, narcotics, alcohol, or tranquilizers.
  3. most often in teenagers.
  4. in the presence of periodontal disease.

 

 

 

 

 

The answer is: B

 

14- A test cavity:

  1. Is the first test in diagnostic sequence.
  2. Often results in a dull pain response.
  3. Is employed only when all other test findings are equivocal.
  4. Should be performed with local anesthetic.

 

 

 

 

 

The answer is: C
