|
Identify the nerves that are intended to be anesthetized for local infiltration.
|
terminal nerve endings of the maxillary nerve in the area of the second premolar
|
|
|
Describe the area that will be anesthetized for local infiltration.
|
tooth
pulp root surrounding bone mucosa on buccal side of the tooth |
|
|
How is the injection site prepared for local infiltration?
|
dry and apply topical anesthetic
|
|
|
How should the syringe be held and where should the needle be inserted for local infiltration?
|
syringe held parallel to long axis of tooth
needle inserted into height of mucobuccal fold adjacent to target tooth |
|
|
What should be done if blood is aspirated?
|
reposition the needle until no blood is reaspirated
|
|
|
Identify the nerves that are intended to be anesthetized for an inferior alveolar nerve block.
|
inferior alveolar nerve
lingual nerve |
|
|
Describe the areas that will be anesthetized for an inferior alveolar nerve block.
|
mandibular teeth to the midline
buccal mucosa anterior to first molar (mental nerve) anterior 2/3 of the tongue, lingual soft tissue and mucosa (lingual nerve) |
|
|
How wide should the patient open his/her mouth for an inferior alveolar nerve block?
|
as wide as possible
|
|
|
What should be palpated when preparing for an inferior alveolar nerve block?
|
coronoid notch and the concavity on the posterior border of the ramus
|
|
|
What should be visualized when preparing for an inferior alveolar nerve block?
|
mucosal triangle covering the pterygomandibular space, which is bounded on the medial by the pterygomandibular raphe and on the lateral by the ramus of the mandible
|
|
|
What is the target for an inferior alveolar nerve block?
|
where the nerve enters the mandible at the lingula on the medial aspect of the mandible, located at a level on a line connecting the concavity of the anterior border of the ramus and the concavity of the posterior border of the ramus
|
|
|
How should the needle be directed for an inferior alveolar nerve block?
|
toward the lingula, parallel to the mandibular occlusal plane, coming from the direction of the opposite premolars, penetrating the mucosa overlying the anterior boundary of the pterygomandibular space
|
|
|
How far is the needle inserted for an inferior alveolar nerve block?
|
20-25mm
(2/3 the length of the needle) |
|
|
What should be done if bone is contacted early during an inferior alveolar nerve block?
|
redirect the needle medially by slight withdrawal and shifting the syringe to the area of the opposite canine or lateral incisor and insert to appropriate depth
|
|
|
What is the last step for an inferior alveolar nerve block?
|
while withdrawing the needle slowly, inject solution to anesthetize the lingual nerve
