oral injections

Question 1

ridge we see for IAN blocks?

Answer 1

pterygomandibular raphe

Question 2

IAN block (infraalveolar nerve) -V3

Answer 2

• affects lingual and IAN
• all mand teeth, anterior 2/3 of tongue, lingual and buccal gingiva/mucosa fromPREMOLARs anteriorly, skin of lower lip and chin

Question 3

Long buccal block -V3

Answer 3

buccal gingiva opposite mandibular molars

Question 4

Mental nerve block -V3

Answer 4

• targets terminal nerve of inferior alveolar nerve
• buccal/labial gingiva and mucosa from premolars to midline
• palpate to find mental foramen

Question 5

Maxillary division, PSA block -V3

Answer 5

• max molars EXCEPT mesiobuccal root of 1st, buccal gingiva opposite
• needle at mucobuccal fold and advance medially, superiority and posterior from 2nd molar

Question 6

MSA Block -V3

Answer 6

NOT SPECIFIC

• max premolar and mesiobuccal root of 1st molar
• may substitute with local infiltration
• insert needle at mucobuccal fold superior to 2nd premolar

Question 7

ASA/Infraorbital Block -V3

Answer 7

• infrequently used do to risk to damage eye
• max teeth from mesibuccal root of 1st molar to midline; buccal/labial gingiva, lateral nose, lower eyelid
• palapte for infraorbital foramen
• hits both MSA and infraorbital nerve

Question 8

Greater palatine block -V3

Answer 8

• palatal gingiva and mucosa from 1st premolar posterioly at midline
• pressure anethesia helpful
• locate great palatine foramen

Question 9

Nasopalatine block – V3

Answer 9

***MOST PAINFUL bc of intimate attachment of mucosa lining to palate
use pressure
*palateal gingiva and mucosa from canine to canine
*insert needle lateral to foramen and *deposit small amounts and then approach directly and SLOWLY inject

Question 10

Maxillary block -V2

Answer 10

use for extensive dental work (hemimaxillary anesthesia)
deposit anesthetic in PPF
locate greater palatine foramen, pressure, inject

Question 11

What happens if the needle is not keep close to maxilla for Maxillary division, PSA block?

Answer 11

the lateral pterygoid muscle (causing trismus) and pterygoid venous plexus (causing hematoma) may be entered

Question 12

trismus

Answer 12

spasm of the jaw muscles, causing the mouth to remain tightly closed, typically as a symptom of tetanus

Question 13

hematoma

Answer 13

a solid swelling of clotted blood within the tissues

Question 14

local infiltration

Answer 14

targeting the terminal branches (instead of entire MSA to get a more specific injection)

Question 15

pressure anesthesia

Answer 15

typical use of cotton swab to apply pressure and reduce sensitivity of region of injection (better with lidocaine on swab)

Question 16

Nasopalatine block application

Answer 16

1) insert needle lateral to foramen and deposit small amounts to desensitize area
2) then approach directly and SLOWLY inject

Question 17

Nasopalatine block andmaxillary block of V2 application

Answer 17

1) insert needle lateral to foramen and deposit small amounts to desensitize area
2) then approach directly and SLOWLY inject
* do this because painful

Question 18

use what block for extensive dental work?

Answer 18

Maxillary block -V2

Question 19

use what block for extensive dental work?

Answer 19

Maxillary block -V2

Question 20

negative aspiration

Answer 20

pulling out after you stick needle in to ensure you do not have blood in syringe
**don’t want to hit vessels
