Exam 36: Anatomical Considerations of Local Anesthesia

The regional nerve block affects a much larger area and more teeth because it affects larger nerves.

What are two ways to lessen the pain from injecting into tissue? (Select all that apply. )

The auriculotemporal nerve may be anesthetized with a

MATCHING Match the area with the procedure used to anesthetize it: -Auriculotemporal nerves

Which block can cause a hematoma? (Select all that apply. )

None of the following anesthetics can be used for mandibular supraperiosteal injections EXCEPT one.Which one is the EXCEPTION?

Which of the following preexisting medical conditions should be considered before making decisions concerning anesthesia? (Select all that apply. )

The nerve exits the tooth at the root apex.

Manual pressure is applied at the injection site during use of a mental block.

Vasoconstrictors contain preservatives to increase effectiveness.

A mental block affects the facial periodontium and gingiva of the mandibular premolars and anterior teeth to the midline.

It is necessary to have a good understanding of the root's width in order to properly perform supraperiosteal injections.

The injection site for maxillary injections is not directly above the target area but one-half tooth distal to the target.

There are three palatal nerve blocks that provide anesthesia to the palatal periodontium and gingiva;they affect only the lingual tissues.

MATCHING Match the area with the procedure used to anesthetize it: -Hard and soft tissues of the palatal periodontium and gingiva of the six anterior teeth

The goal of local anesthesia is to block the innervation from the nerve branches as they try to send their messages back to the brain through the nerves.To do this,the anesthetic solution must reach the nerve branch somewhere between the targeted area to be anesthetized and the nerve trunk.

Infiltration anesthesia affects

The greater palatine nerve block anesthetizes all of the following EXCEPT one.Which one is the EXCEPTION?

A crossover effect is created when nerves and blood vessels do not stop at the midline because some nerve branches crossover into an area innervated by another adjacent nerve.

There are five maxillary nerve blocks delivered from the facial side.
