H&N ANATOMY Chapter 9

Which of the following local anesthesia nerve blocks can be used during cosmetic restorative procedures because, after procedures are completed, the clinician can immediately and accurately access the patient’s smile line?

• Posterior superior alveolar nerve block

• Anterior middle superior alveolar nerve block

Which of the following local anesthesia nerve blocks is usually NOT used bilaterally due to possible complications associated with swallowing and speech?

• Incisive nerve block

• Inferior alveolar nerve block

As a result of a bicycle accident, a patient has suffered trauma to the right upper lip and maxillary right central incisor. Which of the following local anesthetic blocks may be used on the involved side when treating the injured tissue?

• Anterior superior alveolar, infraorbital, and incisive nerve blocks

• Infraorbital and nasopalatine nerve blocks

Orientation of the syringe for the anterior middle superior alveolar nerve block SHOULD be from the contralateral premolars. The angle of the needle SHOULD be placed at approximately 45 degrees to the injection site.

• Both statements are true.

• Both statements are false.

Which of the following local anesthetic nerve blocks uses the apex of the maxillary canine for a landmark during administration?

• Infraorbital nerve block

• Anterior superior alveolar nerve block

When administering a local anesthetic agent to a patient’s teeth and their related dental structures, which three bones of the head and neck have the landmarks essential for clinically effective injection technique?

• Maxillae, mandible, and palatine bones

• Maxillae, mandible, and sphenoid bones

Only one injection is necessary when anesthetizing BOTH the right and left maxillary anterior palate and associated palatal gingival tissue. Pressure anesthesia during the nasopalatine local anesthetic nerve block is NOT helpful with patient comfort.

• The first statement is true; the second statement is false.

• The first statement is false; the second statement is true.

Which of the following descriptions concerning the injection site for the anterior middle superior alveolar local anesthetic nerve block is CORRECT?

• Approximately midway between the median palatine raphe and the palatal gingival margin of the maxillary premolars

• Approximately10 mm medial and directly superior to the palatal gingival margin of the maxillary third molar, anterior to the depression of the greater palatine foramen

Which of the following local anesthetic nerve blocks when administered together would provide the GREATEST area of anesthesia to a maxillary quadrant?

• Middle superior alveolar, posterior superior alveolar, and greater palatine nerve blocks

• Anterior middle superior alveolar and posterior superior alveolar nerve blocks

Before periodontal scaling near the periodontal tissue clefting present on the facial surface of ALL the mandibular incisors of a patient, which local anesthetic block(s) would be the BEST to have administered bilaterally?

• Infraorbital block

• Incisive block
