maxillary anesthesia

An extraoral hematoma can result from an incorrectly administered PSA block because the needle was over-inserted and penetrated which of the following?

• uParotid salivary gland

• Pterygoid plexus of veins

• Floor of the nose

• sinus cavity

You are doing a procedure on the Buccal surfaces of tooth #2 & 3.  You decide to perform a right PSA block for the procedure.  The patient reports that she can feel pain while you are working on MB #3.  If the mesiobuccal root of the maxillary first molar is not anesthetized by the PSA block, what should you do?

• Re-inject at the same site for the PSA block to provide additional anesthetic

• Administer a Greater Palatine block

• Administer an MSA block

• Administer a Nasopalatine block

The injection site for the Greater Palatine block is usually located on the palate near which of the following?

• Maxillary first premolar

• Maxillary second premolar

• Maxillary first molar

• Maxillary second molar

the ASA will anesthetize which teeth?

• 1st and 2nd maxillary molars

• 1st and 2nd maxillary premolars

• Bi-lateral Maxillary canine, lateral, and central incisors

• Uni-lateral maxillary canine, lateral, and central incisors

Anesthesia of the maxillary teeth is more successful than the mandibular teeth because the maxillary structures are LESS dense and MORE porous.

• TRUE

• FALSE

Which of the following local anesthetic blocks requires the needle and syringe barrel angulation to be at 45-degrees within three separate planes during administration?

• Anterior superior alveolar block

• Middle superior alveolar block

• Posterior superior alveolar block

• Greater Palatine

Where is the recommended injection site or needle insertion point for the nasopalatine block?

• Anterior to the greater palatine foramen

• Posterior to the incisive foramen

• Near the maxillary labial frenum

• Lateral to the incisive papilla

The Greater Palatine block provides pulpal anesthesia to the maxillary molars

• TRUE

• FALSE

What is the depth of needle insertion for the PSA block?

• 1/4 of needle

• 1/2 of needle

• 3/4 of needle

• insert all the way to the hub
