Question 1

Practices to avoid when administering local anesthetic include which of the following?

Accepted Answer

Local anesthesia should be administered only in the areas of treatment that can be completed in one visit.Overestimating the treatment and administering more anesthesia than necessary should be avoided,as should not using enough anesthetic for patient comfort and hemostatic control.

Question 2

MATCHING
Match the name of the maxillary injection to the landmarks of the injection site and/or the area that receives the anesthesia. Names of injections may be used more than once.
-Pulpal anesthesia of first and second maxillary premolars in a small percentage of the population

Accepted Answer

DThe Middle Superior Alveolar (MSA) injection is used to anesthetize the first and second maxillary premolars in a portion of the population where this nerve exists. However, in cases where the MSA nerve is absent, the Infraorbital (D) nerve block can provide pulpal anesthesia to the first and second maxillary premolars, as the infraorbital nerve innervates the area from the central incisor to the midline of the maxilla, including the associated teeth and their pulps.

Question 3

What is a good reason not to use distracters when administering maxillary anesthesia?

Accepted Answer

In the past,shaking the patient's upper lip with the clinician's retraction fingers was used to distract the patient during the injection,but this movement may actually increase discomfort because the needle bevel is moved and the anesthetic may not be placed at the target area.

Question 4

What is the name of the type of injection that anesthetizes a larger area than the local infiltration because the local anesthetic agent is deposited near large nerve trunks?

Accepted Answer

Nerve block is the name of the type of injection that anesthetizes a larger area than the local infiltration because the local anesthetic agent is deposited near large nerve trunks.

Question 5

MATCHING
Match the name of the maxillary injection to the landmarks of the injection site and/or the area that receives the anesthesia. Names of injections may be used more than once.
-Lateral to the incisive papilla

Accepted Answer

The nasopalatine injection is administered lateral to the incisive papilla, which is a landmark of the injection site. None of the other injections are administered in this area.

Question 6

There is less variation in the anatomy of the mandibular anesthetic landmarks than there is in similar maxillary structures,thus making the mandibular injections more routine.Anesthesia in the maxillary arch usually does not require any troubleshooting of failure cases.

Accepted Answer

Question 7

MATCHING
Match the name of the maxillary injection to the landmarks of the injection site and/or the area that receives the anesthesia. Names of injections may be used more than once.
-Foramen located at the junction of the maxillary alveolar process and palatine bone distal to the maxillary second molar

Accepted Answer

The greater palatine foramen is located at the junction of the maxillary alveolar process and palatine bone distal to the maxillary second molar, which is the landmark for the greater palatine injection.

Question 8

MATCHING
Match the name of the maxillary injection to the landmarks of the injection site and/or the area that receives the anesthesia. Names of injections may be used more than once.
-Pulpal anesthesia of maxillary central incisors

Accepted Answer

The anterior superior alveolar injection is used to anesthetize the maxillary central and lateral incisors, canine, and premolars on the side of the injection.

Question 9

Best practices for increasing patient comfort during the administration of maxillary injections include which of the following?

Accepted Answer

Best practices for increasing patient comfort during the administration of maxillary injections include: the needle should not be moved within the tissue,and there is no bony contact of the overlying sensitive periosteum with the needle.

Question 10

What should the clinician do if she encounters bulky maxillary facial alveolar ridges?

Accepted Answer

A bulky facial alveolar ridge may present problems with ideal angulations for the needle; increasing retraction and moving the needle injection site more superior will usually help adaptation.

Question 11

MATCHING
Match the name of the maxillary injection to the landmarks of the injection site and/or the area that receives the anesthesia. Names of injections may be used more than once.
-Hard palate and overlying soft tissue of the maxillary anterior teeth.

Accepted Answer

The nasopalatine injection is used to anesthetize the hard palate and overlying soft tissue of the maxillary anterior teeth by targeting the nasopalatine nerve as it emerges from the incisive canal.

Question 12

MATCHING
Match the name of the maxillary injection to the landmarks of the injection site and/or the area that receives the anesthesia. Names of injections may be used more than once.
-Upward 45 degrees to occlusal plane,inward and backward 45 degrees to the midsaggital plane

Accepted Answer

The description of the needle angulation (upward 45 degrees to the occlusal plane, inward and backward 45 degrees to the midsagittal plane) matches the Posterior Superior Alveolar (PSA) injection.

Question 13

MATCHING
Match the name of the maxillary injection to the landmarks of the injection site and/or the area that receives the anesthesia. Names of injections may be used more than once.
-Bone overlying incisors,canine,premolars,and sometimes mesiobuccal root of the first molar,as well as upper lip,lower eyelid,and lateral aspect of the nose

Accepted Answer

The description matches the infraorbital injection, which anesthetizes the area supplied by the infraorbital nerve, including the bone overlying the incisors, canine, premolars, and sometimes the mesiobuccal root of the first molar, as well as the upper lip, lower eyelid, and lateral aspect of the nose.

Question 14

MATCHING
Match the name of the maxillary injection to the landmarks of the injection site and/or the area that receives the anesthesia. Names of injections may be used more than once.
-Pulpal anesthesia of the mesiobuccal root of the maxillary first molar in 28% of the population

Accepted Answer

The answer of MATCHING
Match the name of the maxillary injection...

Question 15

MATCHING
Match the name of the maxillary injection to the landmarks of the injection site and/or the area that receives the anesthesia. Names of injections may be used more than once.
-Pulpal anesthesia of the distobuccal root of the maxillary first molar

Accepted Answer

The distobuccal root of the maxillary first molar is innervated by the posterior superior alveolar nerve, which is anesthetized by the posterior superior alveolar injection.

Question 16

Supraperiosteal is the name of the type of injection that anesthetizes a small area of one or two teeth and the associated structures,when the local anesthetic agent is deposited near the terminal nerve endings.
