Exam 9: Anatomy of Local Anesthesia

Which of the following angulations of the needle MUST be followed during the administration of the posterior superior local anesthetic nerve block?

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?

From the following list,select those that are anatomic factors involved in providing MORE clinically effective maxillary arch anesthesia than mandibular arch anesthesia.(Select all that apply. )

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?

Less variation exists in the anatomy of the maxillae and palatine bones and associated nerves with respect to local anesthetic landmarks as compared with similar mandibular structures,making the maxillary injections less routine and usually with the need for any troubleshooting of failure cases.

Which of the following local anesthetic nerve blocks can be involved in the spread of infection to the cavernous sinus?

The dental professional MUST know the location of certain adjacent soft tissue structures,such as major blood vessels and glandular tissue,so as to make sure to allow for injecting these structures.

Which of the following complications can result from a greater palatine local anesthetic nerve block?

A 9-year-old child is having a restoration placed on the occlusal surface of the mandibular left first molar.Which of the following heights of the inferior alveolar local anesthetic nerve block injection sites should be followed during the pain control procedure?

From the following list of oral cavity landmarks,select those that need to be noted before administering a clinically effective inferior alveolar nerve block.(Select all that apply. )

Which of the following ligaments can act as a barrier to the inferior alveolar nerve block if mandibular bone is NOT contacted during the injection?

Which local anesthetic nerve block would be necessary for a patient undergoing oral surgery on an edentulous left mandibular alveolar process in the area of the extracted molars?

Which of the following are included in the linear relationship noted on the face that can assist with the CORRECT administration of the infraorbital block? (Select all that apply. )

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?

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

Which of the following complications can occur during an incorrect administration of the inferior alveolar local anesthetic nerve block,resulting in inability to close the eyelid?

A restoration will be placed on the occlusal surface of the maxillary first premolar,but no rubber dam will be used.However,which of the following local anesthetic nerve blocks MUST be administered?

Which of the following local anesthesia nerve blocks would benefit from using a topical anesthetic-laced long cotton tip applicator to palpate the injection site as if it were the needle and syringe? (Select all that apply. )

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?

Palatal anesthesia usually involves anesthesia of the soft and hard tissue of the periodontium of the palatal area such as the gingival tissue,periodontal ligament,and alveolar process.Palatal anesthesia usually does NOT provide any pulpal anesthesia to the maxillary teeth or associated facial or buccal gingival tissue.
