Anesthesia

Question 1

Supraperiosteal Injection

Answer 1

[local] injections near apices of teeth to anesthetizes 1-2 teeth and tissue

Question 2

Nerve Block

Answer 2

injection deposited near nerve trunk to anesthetizes large area

Question 3

Local Anesthesia: Effectiveness

Answer 3

maxilla more successful - cortical bone is less dense and has less variable anatomy

Question 4

PSA Block

Answer 4

1st (not MB), 2nd, 3rd molars + overlying buccal tissue *injected @ mucobuccal fold above apex of 2nd molar, distal to zygomatic process

Question 5

PSA Block: Incorrect Angulation

Answer 5

penetration of pterygoid plexus of veins - causing hematoma

Question 6

MSA Block

Answer 6

1st, 2nd premolars + MB 1st molar + overlying buccal tissue *injected mucobuccal fold @ apex max. 2nd premolar

Question 7

ASA Block

Answer 7

canine, incisors + overlying facial tissue/lips *mucobuccal fold @ apex of max canine

Question 8

ASA + MSA

Answer 8

can be used together INSTEAD of IO block!

Question 9

IO Block

Answer 9

premolars, canines, incisors + lips *injection @ upper rim of infraorbital foreman, rarely used!

Question 10

Greater Palatine Block

Answer 10

palatal tissue of premolars and molars *injected anterior to depression created by palatine foreman

Question 11

Pressure Anesthesia

Answer 11

pressure nearby to blanch and make injection more tolerable

Question 12

Nasopalatine Block

Answer 12

palatal tissues from left - right canine *injected at palatal tissue lateral to incisive papilla

Question 13

Inferior Alveolar Block

Answer 13

[mandibular block] ALL mandibular teeth in quad EXCEPT buccal soft tissue of molars + lingual nerve * injected in pterygomandibular space

Question 14

Long Buccal

Answer 14

buccal periodontium of mandibular molars *injected at buccal tissue distal to most mand molar [anterior border of ramus]

Question 15

Mental/Incisive Block

Answer 15

mand. premolars, canines, incisors + face/lip anterior to mental foreman *

Question 16

Gow-Gates Mandibular Block

Answer 16

[G-G block, TRUE] entire mandibular nerve: inferior alveolar, lingual, mental, incisive, mylohyoid, auriculotemporal, buccal (75%)

Question 17

Vazirani-Akinosi Mandibular Block

Answer 17

[not true] nerves: inferior alveolar, lingual, mental, incisive, mylohyoid within pterygomandibular, buccal (75%)
