PMQ3 Injections (3)

AMSA Block

numbs all max teeth in one quadrant, commonly used for cosmetics, but not adequate for dental hygiene purposes

Nasopalatine

numbs soft tissue from canine to canine, NO TEETH inject lateral to incisive papilla

Greater palatine block

numbs premolar/molar soft tissue and hard palate in one quadrant, NO TEETH, apply pressure with cotton swab on hard palate only

Incisive nerve block

numbs teeth, periodontium, and facial soft tissue anterior to premolars. Inject anterior to mental foramen at depth of mucobuccal fold, massage the tissue to force solution into mental foramen to get the teeth! (mand)

Mental block tee hee

numbs lower lip and chin to midline as well as facial gingival tissue anterior to mental foramen (no teeth)

Incisive vs Mental

Incisive requires the tissue be massaged in order to anesthetize teeth, Mental is literally exactly the same but you don't massage. Same injection site and angle

Inferior alveolar block (IA)

most commonly used injection in dentistry, numbs so much stuff. Mand teeth, periodontium, lingual/facial soft tissue anterior to mand first molar. ALSO tongue, floor of mouth, lower lip, and chin. Landmark is coronoid notch (this one left your jaw sore!)

IA complications

15 to 20% failure rate, can cause lingual shock

Buccal block

numbs cheek and buccal gingival tissue, administered immediately after IA (bit your cheek). Inject buccal/distal to last molar at height of occlusal plane, make sure not to poke your thumb
