Q

what will get numb if you hit the MSA in pt’s that have it?

A

-mesiobuccal root of the 1st max molar (possibly)
-buccal gingiva and mucosa
-max sinus

22
Q

what will get numb with the ASA

A

-canine and incisors
-facial gingiva and mucosa
-max sinus/nasal cavity

23
Q

what’s another name for the infraorbital nerve block?

A

ASA nerve block

24
Q

what’s an exterior landmark that you can use to hit the infraorbital nerve block?

A

the pupil will line up with foramen

25
Q

with an infraorbital nerve block what will also get numb in addition to the structures that get numb with the ASA/MSA block?

A

lower eyelid
lateral side of nose
upper lip

26
Q

with a maxillary division block what nerves (assoc with dentistry) will be blocked

A

-greater palatine (lesser as well, but not assoc with dentistry)
-nasopalatine
-PSA
-MSA (if present)
-ASA

27
Q

what’s another name for the buccal n.?

A

long buccal

28
Q

what kind of nerve is the buccal nerve? (sensory, motor, mixed) and where does it go to?

A

sensory
-sensation to gingiva along buccal shelf
-retromolar trigone
-all along gingiva of mand molars

29
Q

V3 branch is __________ (sensory, motor, mixed)

A

mixed

30
Q

what is attached to the lingula?

A

sphenomandibular lig

31
Q

T/F local infiltration is better on the mand vs. the max

A

False. the cortical plates are thicker so locals are harder

32
Q

what’s the importance of the mylohyoid line?

A

separates mouth
mylohyoid muscle attaches here

33
Q

what’s the importance of the lingual tuberosity

A

lingual nerve lies in contact with it and it can be compressed with dental work (e.g. exts)

34
Q

what are the 8 muscles that V3 gives motor function to?

A

muscles of mastication:
-temoporalis
-masseter
-medial pterygoid
-lateral pterygoid
Mylohyoid
ant. belly of digastric
tensor tympani
tensor veli palatini

35
Q

all ant./post. divisions of the mandible are part of what fossa?

A

infratemporal fossa

36
Q

what is the auriculotemporal nerve asssoc with regarding dentistry?

A

the nerve of the TMJ

37
Q

what division does the buccal n. belong to?

A

the ant. division

38
Q

what division does the lingual, IA, incisive, & mental nn’s belong to?

A

post. division

39
Q

T/F the incisive n. goes to the soft tissue while the mental n. goes to the teeth

A

false!
mental = soft tissue
incisive = teeth

40
Q

what muscle does the buccal nerve pierce?

A

the buccinator

41
Q

T/F the buccal n. innervates the buccinator

A

False. innervated by facial

42
Q

after it pierces the muscle, where does the buccal nerve lie?

A

along the buccal shelf

43
Q

T/F the buccal nerve will not be anesthetized when doing an IA block

A

True

44
Q

where does the lingual nerve pass?

A

inferiorly on the medial pterygoid in the pterygomandibular space

45
Q

what does the lingual n. innervate?

A

-epithelium of the ant. 2/3rds of tongue
-all lingual gingiva and lingual mucosa along the floor of the oral cavity

46
Q

where does the IA nerve pass?

A

inferiorly on the medial pterygoid in the pterygomandibular space lying lateral to the sphenomandibular lig.

47
Q

what does the IA divide into?

A

the incisive and mental nn’s

48
Q

what does the IA innerveate?

A

all mand teeth & PDL through dental plexus (specifically from molars to 2nd premolar)

49
Q

what will the mental nerve supply?

A

-chin
-buccal gingiva and mucosa from premolars ant.
-lower lip

50
Q

what’s the closest you’ll get to a V3 nerve block?

A

gow-gates
