A
infiltration and nerve block
2
Q

Q
What is the target, action, and area of nerve block LA?
A
A larger nerve trunk by depositing near the nerve trunk. Large area.
4
Q
What do you need to know before administering LA?
A
Which tooth/area-nerve supply, nearby structures,
where to administer for best outcome- nerve pathways, bone quality
vital structures nearby- blood vessels, other vessels
bony/dental soft tissue landmarks- high variability in soft tissue anatomy
5
Q
Describe soft tissue landmarks
A
considerable variability so not reliable but still useful
