Exam 9: Anatomy of Local Anesthesia

When troubleshooting incomplete anesthesia following an inferior alveolar local anesthetic nerve block on a patient,the clinician notes a doubled mandibular canal on an intraoral radiograph.What is present with this patient,and how can clinically effective anesthesia be achieved? (Select all that apply. )

Which of the following local anesthetic nerve blocks anesthetizes the buccal gingival tissue of the maxillary first molar?

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

When administering the inferior alveolar local anesthetic nerve block,it is important to contact bony medial surface of the mandibular ramus because this will decrease the risk of depositing a local anesthetic agent into the parotid salivary gland.

Which of the following local anesthetic nerve blocks MAINLY uses an extraoral landmark on the face when locating the injection site?

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.

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

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

There is ONLY one type of local anesthetic injection used commonly in dentistry,the nerve block.The type of injection used for a given dental procedure is determined by the type and length of the procedure.

There MUST never be an injection through an area with an abscess,cellulitis,or osteomyelitis so as to prevent the spread of dental infection.

Which of the following locations is the BEST injection site for the inferior alveolar local anesthetic nerve block?

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.

Which of the following procedures may allow for LESS discomfort when anesthetizing the palate of a patient with the anterior middle superior alveolar block? (Select all that apply. )

From the following list of complications involving the eyelid,nose,and upper lip,select the MOST common ones associated with the infraorbital nerve block.(Select all that apply. )

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

Which of the following statements can be CORRECTLY used when discussing the "lingual shock" some patients may experience when administering an inferior alveolar local anesthetic block?

From the following list,select those statements that can be used CORRECTLY when discussing paresthesia from the administration of local anesthesia and its progression over time.(Select all that apply. )
