Question 1

From the following list of landmarks, select those which are noted when administering the posterior superior alveolar nerve block by dental professionals.

Accepted Answer

The mucobuccal fold and maxillary tuberosity are anatomical landmarks used to locate the injection site for the posterior superior alveolar nerve block.

Question 2

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.

Accepted Answer

The statement is correct because dental professionals must know the location of adjacent soft tissue structures to avoid them during procedures. However, the reason is incorrect because the goal is to avoid injecting into these structures, not to allow for injecting them.

Question 3

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.

Accepted Answer

The statement is correct because maxillary injections are generally more routine and require less troubleshooting due to less anatomical variation. However, the reason provided is incorrect because less variation in anatomy actually makes maxillary injections more predictable, not less.

Question 4

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 bone. Palatal anesthesia usually does NOT provide any pulpal anesthesia to the maxillary teeth or associated facial or buccal gingival tissue.

Accepted Answer

Palatal anesthesia typically affects the palatal tissues but does not extend to the pulpal tissues or the facial/buccal gingiva of the maxillary teeth.

Question 5

From the following list of descriptions, select those that can be COMMONLY used when describing paresthesia and its progression.

Accepted Answer

The answer of From the following list of descriptions, select...

Question 6

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

Accepted Answer

The statement is correct as injection through an area with an abscess, cellulitis or osteomyelitis can spread the dental infection. The reason is also correct and related to the statement as it explains why this should not be done in order to prevent the spread of infection.

Question 7

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

Accepted Answer

The infraorbital nerve block mainly uses an extraoral landmark on the face (the infraorbital foramen) to locate the injection site. The other options involve intraoral landmarks.

Question 8

From the following list of landmarks, select those which are noted by dental professionals when administering the inferior alveolar nerve block by dental professionals.

Accepted Answer

The answer of From the following list of landmarks, select...

Question 9

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

Accepted Answer

The answer of Which of the following local anesthetic nerve...

Question 10

From the following list of descriptions, select those that are factors involved in maxillary nerve anesthesia.

Accepted Answer

The answer of From the following list of descriptions, select...

Question 11

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.

Accepted Answer

There are multiple types of local anesthetic injections used in dentistry, including nerve blocks, infiltration, and intraligamentary injections, among others. The choice of injection is indeed determined by the type and length of the procedure, among other factors.

Question 12

From the following list of complications involving the eyelid, nose, and upper lip, select the MOST common ones associated with the infraorbital nerve block.

Accepted Answer

The answer of From the following list of complications involving...
