1. The inferior alveolar nerve block has the highest failure rate not
only in dental local anesthesia, but also among all local anesthetic blocks
in medicine.
A. True.
B. False.
2. Previous research illustrated several explanations for posterior
mandibular anesthesia failure, including:
A. Patient anxiety.
B. Central core theory.
C. Both A and B.
D. None of the above.

6. The "accessory innervation to the inferior alveolar nerve" theory
had not been universally accepted because of:
A. The lack of anatomical evidence demonstrating that
the auriculotemporal nerve innervates teeth.
B. The lack of anatomical evidence demonstrating that
the mylohyoid nerve can extend to the mandible.
C. The lack of anatomical evidence demonstrating that
the cervical plexus nerve can extend to the mandible.
D. This theory will never be accepted.
7.

In order to achieve pulpal anesthesia in the posterior mandible,
A. An accessory innervation anesthetic device (AIAD) that
anesthetizes all the accessory nerves must be devised.
B. An accessory innervation anesthetic protocol (AIAP) that
anesthetizes all the accessory nerves must be devised.
C. An accessory innervation anesthetic software (AIAS) that
anesthetizes all the accessory nerves must be devised.
D. None of the above.

Which anesthetic technique below blocks the auriculotemporal nerve?
A. Cervical plexus anesthetic technique.
B. Gow-Gates.
C. Mental nerve.
D. Intraligamentary.

Which nerve arises from the spinal cord?
A. Trigeminal.
B. Facial.
C. Cervical plexus.
D. None of the above.

3. Which is not one of the theories of posterior mandibular anesthetic
failure?
A. Nerve altered resting potentials.
B. Tetrodotoxin-resistant (TTXr) class sodium channels.
C. Ehlers-Danlos syndrome.
D. Having blond hair.
4.

Posterior mandible pulpal anesthesia can be determined when we find:
A. Half of the lip numb.
B. Half of the tongue numb.
C. Negative response to the cold test.
D. None of the above.

5. The accessory innervation theory supports that incidents of
unsuccessful anesthesia may result from innervations of the adult mandible
arising from the cervical plexus, in addition to the auriculotemporal, buccal,
mental, incisive, mylohyoid, incisal and lingual nerves.
A. True.
B. False.

10. The intraoral cervical plexus anesthetic technique utilizes:
A. A short/30-gauge needle and 45 degrees angulation.
B. A long/30-gauge needle and 45 degrees angulation.
C. A short/30-gauge needle and 30 degrees angulation.
D. A long/30-gauge needle and 30 degrees angulation.
