Question 1

What injection,besides the IA block,should be considered if the clinician will be performing nonsurgical periodontal therapy on the mandibular molars?

Accepted Answer

Use of the buccal block may be considered if anesthesia of the buccal soft tissue of the mandibular molars is necessary,which is usually the case with nonsurgical periodontal therapy.

Question 2

MATCHING
Match the name of the mandibular 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 true mandibular block because it anesthetizes almost the entire mandibular nerve

Accepted Answer

The Gow-Gates injection is a true mandibular block because it anesthetizes almost the entire mandibular nerve. None of the other options anesthetize the entire nerve.

Question 3

What usually causes the discomfort associated with the IA injection?

Accepted Answer

The discomfort is mainly due to the reaction to the needle near the lingual nerve or lingual shock.

Question 4

Lingual shock may occur as the needle passes by the inferior alveolar nerve during the IA block.

Accepted Answer

Correct: Lingual shock may occur as the needle passes by the lingual nerve during the IA block.

Question 5

When administering the buccal block and the tissue balloons up,the clinician should correct this by deeper penetration of the bevel of the needle.

Accepted Answer

Correct: A complication with the buccal block,the ballooning of the tissue,is caused by rapid deposit of solution; correct by slowing down the injection.

Question 6

With the PDL injection,multirooted teeth require an injection for each root.

Accepted Answer

Multirooted teeth have more than one root, so each root requires a separate injection of PDL.

Question 7

MATCHING
Match the name of the mandibular 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.
-Injection site is the alveolar mucosal tissue,distal and buccal to the most distal molar tooth in the arch

Accepted Answer

The description matches the buccal block, which is administered in the alveolar mucosal tissue distal and buccal to the most distal molar tooth in the arch to anesthetize the buccal soft tissues adjacent to the mandibular molars.

Question 8

MATCHING
Match the name of the mandibular 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.
-Middle of pterygomandibular triangle at the height of the coronoid notch

Accepted Answer

The injection site described is the location for the inferior alveolar (IA) block injection. None of the other injections are given at this specific location.

Question 9

The periodontal ligament injection is administered directly into the periodontium of the tooth providing pulpal anesthesia along with the lingual and buccal mucosa.

Accepted Answer

The periodontal ligament injection is administered directly into the periodontium of the tooth, which provides pulpal anesthesia as well as the lingual and buccal mucosa.

Question 10

Because the bone is denser on the mandibular anterior teeth than on the mandibular posterior teeth,a supraperiosteal injection may be less successful than a supraperiosteal injection on the posterior teeth.

Accepted Answer

Correct: Because the bone is less dense on the mandibular anterior teeth compared to the mandibular posterior teeth,a supraperiosteal injection may be more successful than a supraperiosteal injection on the posterior teeth.

Question 11

Which is the correct order for the administering of injections?

Accepted Answer

The inferior alveolar and buccal blocks are given first,then the maxillary facial injections and then palatal injections,in that order.

Question 12

MATCHING
Match the name of the mandibular 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.
-Anesthesia of the anterior teeth,premolar teeth,and associated periodontium as well as facial soft tissue anterior to the mental foramen

Accepted Answer

The incisive block is the injection that anesthetizes the anterior teeth, premolar teeth, and associated periodontium as well as facial soft tissue anterior to the mental foramen. None of the other injections listed have this specific area of anesthesia.

Question 13

MATCHING
Match the name of the mandibular 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.
-Useful for extensive procedures during quadrant dentistry or with failure of IA block

Accepted Answer

The Gow-Gates injection is the most useful for extensive procedures during quadrant dentistry or with failure of IA block. It is a deep and wide-ranging injection, targeting multiple nerves in the area. The IA block, mental block, and incisive block are all more localized injections and may not provide enough anesthesia for extensive procedures or in cases of IA block failure. The buccal block only provides anesthesia to the buccal soft tissues and is not relevant for mandibular procedures.

Question 14

Periodontal ligament injections are utilized when pulpal anesthesia is indicated on a single tooth in the mandibular arch.

Accepted Answer

Periodontal ligament injections are a type of local anesthesia that can be used to provide pulpal anesthesia to a single tooth in the mandibular arch. The injection is administered into the periodontal ligament space surrounding the root of the tooth, providing a very localized and effective form of anesthesia.

Question 15

MATCHING
Match the name of the mandibular 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.
-Message anesthetic solution into foramen

Accepted Answer

The incisive block involves injecting anesthetic solution near the mandibular incisors, at or near the mandibular foramen.

Answer: A 
 The IA block involves injecting anesthetic solution near the mandibular foramen, which is located at the level of the mandibular occlusal plane between the mandibular first and second molars.

Answer: E 
 The Gow-Gates injection involves injecting anesthetic solution near the condylar process of the mandible, which is located inferior to the mandibular foramen. This injection is used for more extensive anesthesia of the mandibular teeth and surrounding tissues.

The buccal block and mental block do not involve injecting near the mandibular foramen and are therefore not the best choices for the given statement.

Question 16

Anesthesia of the lingual nerve requires a separate technique and/or injection.

Accepted Answer

Correct: The lingual nerve will be anesthetized as the local anesthetic agent diffuses while injecting the IA block,so there is no need for a separate injection for this nerve.

Question 17

MATCHING
Match the name of the mandibular 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.
-Needle penetration depth is approximately 20 to 25 mm or two thirds to three fourths of long needle

Accepted Answer

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

Question 18

MATCHING
Match the name of the mandibular 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.
-Does not message anesthetic solution into foramen

Accepted Answer

The mental block injection is administered at the mental foramen, which is located on the anterior surface of the mandible. It does not go into the foramen.

Answer: A
 The IA block injection is administered near the mandibular foramen, but does not enter it.

Answer: D
 The incisive block injection is administered into the incisive canal, which houses the nasopalatine nerve.

Answer: B
 The buccal block injection is administered near the mental foramen and the height of the mucobuccal fold, but it does not involve any particular foramen.

Answer: E
 The Gow-Gates injection is administered near the condylar process and goes deeper and more posteriorly than other injections. It does not involve the mental foramen.

Question 19

There is more variation in the anatomy of the mandibular anesthetic landmarks than in similar maxillary structures.Lack of consistent success with the IA block injection is due in part to anatomic variations.

Accepted Answer

There is more variation in the anatomy of the mandibular anesthetic landmarks than in similar maxillary structures.Lack of consistent success with the IA block injection is due in part to anatomic variations.

Question 20

In most cases,paresthesia occurs due to problematic surgical extraction of impacted molars.

Accepted Answer

Paresthesia, or numbness and tingling sensation in the mouth, tongue, or face, is a common complication of surgical extraction of impacted molars. It can occur due to nerve damage during the surgery.
