MCQs in Endodontics

Chapter 18: Management of pain


1- The duration of action of a local anesthetic can be increased by:

  1. increasing its lipid solubility.
  2. increasing its protein-binding potential.
  3. decreasing its extra-neural tissue diffusibility.
  4. increasing its vasodilator activity.







The answer is: B


 2- Inadequate anesthesia in some cases of inflamed or infected pulps is due to:

  1. a decrease in the tissue pH around the involved tooth.
  2. availability of more cations for binding at the receptor site.
  3. a larger proportion of the free base.
  4. a smaller proportion of the cation.







The answer is: A


 3- Supraperiostcal anesthesia is:

  1. most effective in areas of infection.
  2. generally used for pulpal anesthesia ol" maxillary teeth.
  3. not effective for primary teeth in the mandibular arch.
  4. effective in areas of dense cortical bone.






 The answer is: B


 4- The infraorbital nerve block does not anesthetize:

  1. the maxillary premolar.
  2. the maxillary incisors.
  3. the palatal mucosa.
  4. the maxillary cuspid.






The answer is: C


 5- Partial anesthesia to the mesial of the mandibular first molar can be alleviated by:

  1. anesthetizing the motor fibers of the mylohyoid nerve.
  2. depositing anesthetic on the buccal side at the level of the mesial apex.
  3. depositing anesthetic on the lingual side at the level of the apex of the second molar.
  4. all of the above.






The answer is: C


 6- Electronic dental anesthesia (EDA):

  1. has not been approved by the FDA for intraoral pain control.
  2. can be used without local anesthesia for pulp extirpation.
  3. has been successful as a technique for post-endodontic surgery patient management.
  4. has not been successful as an adjunct in treating "hot" mandibular molars.






The answer is: C


 7- Conscious sedation is a technique designed to:

  1. control pain.
  2. control anxiety.
  3. control pain and anxiety.
  4. affect the patient's protective reflexes.






The answer is: B


 8- Oral sedation:

  1. is the most frequently employed technique of pharmacosedation.
  2. is quick acting.
  3. is short acting.
  4. is least accepted by patients compared with other routes of drug administration.






The answer is: A


 9- Disadvantages of intramuscular sedation include:

  1. inability to titrate to the ideal level of sedation.
  2. inability to deepen the level of sedation.
  3. inability to lighten the level of sedation.
  4. all of the above.







The answer is: D


 10- When sedation is required the most advantageous route of administration is:

  1. oral.
  2. inhalation.
  3. intramuscular.
  4. intravenous.







The answer is: B


 11- Compared to diazepam (Valium), midazolam (Versed):

  1. provides an amnesic effect,
  2. is not as potent.
  3. requires no local anesthetic for pain control.
  4. provides a greater degree of sedation.







The answer is: A


 12- Which route of administration of conscious sedation requires no one to escort the patient from the office:

  1. Oral.
  2. Intravenous.
  3. Inhalation.
  4. None of the above.






The answer is: C
