Question 1

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
A)Anterior superior alveolar injection
B)Middle superior alveolar injection
C)Posterior superior alveolar injection
D)Infraorbital
E)Nasopalatine
F)Greater palatine

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 2

A) Both statements are true.
B) Both statements are false.
C) The first statement is true;the second statement is false.
D) The first statement is false;the second statement is true.

Accepted Answer

D

Question 3

Practices to avoid when administering local anesthetic include which of the following?
A) Not using enough for patient comfort and hemostatic control
B) Overadministering of anesthesia
C) Administering anesthesia to a larger treatment area than can be completed in one visit
D) All options listed

Accepted Answer

All of the listed practices should be avoided when administering local anesthetic. It is important to use enough anesthetic to ensure patient comfort and control bleeding, but over-administering can lead to potential complications. Similarly, treating a larger area than can be completed in one visit can also lead to complications and discomfort for the patient.

Question 4

What is a good reason not to use distracters when administering maxillary facial anesthesia?
A) The clinician needs her fingers for retraction of the upper lip.
B) Pulpal anesthesia may be blocked.
C) Movement may cause the anesthetic not to be placed at the target area.
D) All options listed.

Accepted Answer

Using distracters can cause movement, which may result in the anesthetic not being placed accurately at the target area, potentially leading to ineffective anesthesia.

B)Middle superior alveolar injection
C)Posterior superior alveolar injection
D)Infraorbital
E)Nasopalatine
F)Greater palatine

Accepted Answer

The distobuccal root of the maxillary first molar is innervated by the posterior superior alveolar nerve, making the posterior superior alveolar injection the best choice for pulpal anesthesia in this area.

Question 12

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
A)Anterior superior alveolar injection
B)Middle superior alveolar injection
C)Posterior superior alveolar injection
D)Infraorbital
E)Nasopalatine
F)Greater palatine

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 13

What 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?
A) Nerve block
B) Supraperiosteal
C) Topical
D) Palatine injections

Accepted Answer

The type of injection described is a supraperiosteal injection, where the anesthetic agent is deposited near the terminal nerve endings to anesthetize a small area of one or two teeth and the associated structures. Nerve blocks anesthetize larger areas by blocking the entire nerve bundle, topical anesthesia is applied directly to the surface of the mucous membrane, and palatine injections anesthetize the palate.

Question 14

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.

-Height of mucobuccal fold above the first premolar
A)Anterior superior alveolar injection
B)Middle superior alveolar injection
C)Posterior superior alveolar injection
D)Infraorbital
E)Nasopalatine
F)Greater palatine

Accepted Answer

The infraorbital injection is administered at the height of the mucobuccal fold above the first premolar, targeting the infraorbital foramen to anesthetize the infraorbital nerve, which affects the maxillary central incisor through the maxillary premolars.

Question 15

Best practices for increasing patient comfort during the administration of maxillary injections include which of the following?
A) The needle should not be moved within the tissue.
B) The patient's upper lip should not be slightly jiggled for distraction.
C) There is no bony contact of the overlying sensitive periosteum with the needle.
D) All options listed

Accepted Answer

All options listed are best practices for increasing patient comfort during maxillary injections. The needle should not be moved within the tissue to avoid unnecessary pain and tissue damage. Jiggling the upper lip can cause more discomfort and should be avoided. Ensuring there is no bony contact of the needle with the sensitive periosteum will decrease pain during injections. Combining all these techniques will create a more comfortable experience for the patient.

Question 16

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.
A)Anterior superior alveolar injection
B)Middle superior alveolar injection
C)Posterior superior alveolar injection
D)Infraorbital
E)Nasopalatine
F)Greater palatine

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 17

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.

A)Anterior superior alveolar injection
B)Middle superior alveolar injection
C)Posterior superior alveolar injection

E)Nasopalatine
F)Greater palatine

Accepted Answer

The description matches the technique for administering a Posterior Superior Alveolar (PSA) injection, which is aimed at anesthetizing the maxillary molars (except for the mesiobuccal root of the first molar). The needle is directed upward at a 45-degree angle to the occlusal plane and inward/backward at a 45-degree angle to the midsagittal plane to target the PSA nerve.

B)Middle superior alveolar injection
C)Posterior superior alveolar injection
D)Infraorbital
E)Nasopalatine
F)Greater palatine

Accepted Answer

The Anterior Superior Alveolar (ASA) injection is administered slightly mesial to the canine eminence and at the height of the mucobuccal fold to anesthetize the maxillary anterior teeth and their associated structures.

Question 19

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
A)Anterior superior alveolar injection
B)Middle superior alveolar injection
C)Posterior superior alveolar injection
D)Infraorbital
E)Nasopalatine
F)Greater palatine

Accepted Answer

The nasopalatine injection is administered lateral to the incisive papilla, targeting the nasopalatine nerve as it emerges from the incisive canal to anesthetize the anterior portion of the hard palate and the palatal tissues of the maxillary incisors.

Question 20

In which order would you administer the maxillary injections?
A) Greater palatine,PSA
B) Infraorbital,PSA
C) PSA,MSA,ASA
D) Order of anesthetic is at the discretion of the clinician

Accepted Answer

The maxillary injections are typically given in the following order: PSA, MSA, and ASA. This sequence ensures that the areas of the posterior, middle, and anterior parts of the maxillary teeth are anesthetized in a logical and organized manner.
