Mandibular anesthesia

Which of the following nerves is NOT anesthetized during an IA block?

• buccal nerve

• mental nerve

• incisive nerve

• lingual nerve

Which of the following local anesthetic blocks has the same injection site as the incisive block?

• Inferior Alveolar

• Mylohyoid

• Buccal

• Mental

Which of the following is an important landmark to locate before performing an inferior alveolar block?

• Coronoid Notch

• Buccal Fat Pad

• Mental Foramen

• Tongue

Temporary facial paralysis can occur with which incorrectly administered block?

• Incisive

• Mylohyoid

• PSA

• IA

Which of these situations is occurring if bone is contacted too soon in an IA Block?

• Needle tip is located too far anteriorly on the ramus

• Needle tip is located too far posteriorly on the ramus

• Syringe barrel is over the occlusal plain of the same side being anesthetized

Your patient needs treatment on teeth #’s 21-28.  She is only available for 1 appointment due to difficulty of taking off of work. Which choice is best for the patient?

• Bilateral IA Block

• Bilateral Long Buccal block

• Bilateral mental/mylohyoid blocks

• Bilateral Incisive/mylohyoid Blocks

After anesthetizing that same patient, she stops you to report that her chin feels extremely numb. What should you do next for the patient?

• Stop treatment and explain facial nerve paralysis to the patient

• Explain to the patient that this is the usual reaction and continue with treatment

• Place a cold compress to prevent hematoma from occurring

• Immediately administer an oral antihistamine to reduce inflammation

Which of the following injections anesthetizes the buccal tissues of the mandibular molars?

• IA

• Mental

• Incisive

• Long Buccal

When administering the inferior alveolar block, the syringe barrel in MOST cases should usually be over which mandibular tooth?

• Premolar on the injection side

• Premolar on the contralateral side

• First molar on the contralateral side

• First molar on the injection side

While administering the inferior alveolar block, you contact bone at a depth of ¾ of the needle. What should the clinician do next?

• Slightly withdraw the needle and redirect the syringe barrel more posteriorly

• Slightly withdraw the needle and redirect the syringe barrel more anteriorly

• Aspirate correctly and then deposit anesthetic agent at the site

• Slightly withdraw the needle and redirect the syringe barrel more perpendicularly to the mandibular occlusal plane
