Term
Anterior Superior Alveolar (ASA)
Definition
Needle: short 25/27 gauge
Penetration Site: height of mucobuccal fold above canine
Depth of Insertion: variable, needle tip inserted to a point above apex of canine
Angle of Insertion: needle directed 25 degrees medially bevel toward bone
Target: above apex of canine
Dose: 0.9-1.2ml
Field of Anesthesia: canine, lateral, central, facial to affected teeth
Term
Middle Superior Alveolar (MSA)
Definition
Needle: short 25/27 gauge
Penetration Site: height of mucobuccal fold above the second premolar
Depth of Insertion: variable, needle tip inserted to a point well above apex of second premolar
Angle of Insertion: needle directed 20 degrees medially bevel toward bone
Target: well above apex of second premolar
Dose: 0.9-1.2ml
Field of Anesthesia: maxillary premolars and mesiobuccal root of first molar, facial to affected teeth
Term
Posterior Superior Alveolar (PSA)
Definition
Needle: short 25/27 gauge
Penetration Site: height of mucobuccal fold above second molar
Depth of Insertion: needle tip inserted to a depth of 16mm
Angle of Insertion: needle advanced along a path 45 degrees medially to midsaggital plane, 45 degrees superior to occlusal plane
Target: slightly above and distal to distobuccal root of last molar, second or third if present
Dose: 0.9-1.8ml
Field of Anesthesia: maxillary molars except mesiobuccal root of first molar, buccal to affected teeth
Term
Maxillary Infiltration
Definition
Needle: extra short or short 25/27/30 gauge
Penetration Site:height of mucobuccal fold buccal to tooth
Depth of Insertion: needle tip inserted to a depth of 3-6mm to apex
Angle of Insertion: approximately 20 degrees to long axis of tooth, directed toward apex of tooth bevel toward bone
Dose: 0.6ml
Field of Anesthesia: at injection site
Term
Greater Palatine (GP)
Definition
Needle: extra short or short 25/27 gauge
Penetration Site: in the anterior depression of the GP foramen, at junction of palatine bone and alveolar process above and lingual to second molar
Depth of Insertion: needle inserted to 4-6mm(to bony resistance)
Angle of Insertion: from opposite side of mouth at right angle to target area bevel toward palate
Target: greater palatine foramen
Dose: 0.4-0.6ml
Field of Anesthesia: palatal tissues of posterior teeth
Term
Palatial Anterior Superior Alveolar (PASA)
Definition
Needle: extra short or short 30/27 gauge
Penetration Site: Infiltration: just lateral to incisive papilla; Block: center of papilla on midline
Depth of Insertion: 6-10mm
Angle of Insertion: approach at 45 degree angle bevel toward palate
Target: beneath incisive papilla, slightly into incisive foramen
Field of Anesthesia: central, lateral, canine, periodontium of affected teeth
Term
Buccal (LB)
Definition
Needle: short (when given along) or long (usually given following IA) 25/27 gauge
Penetration Site: mucous membrane distal and lateral to most posterior molar
Depth of Insertion: equal to or less than 4mm, bevel under tissue, bevel toward bone
Angle of Insertion: syringe parallel to occlusual plane, lateral to teeth, bevel toward bone
Target: suproperiosteal, distal, and buccal to most posterior molar
Dose: 0.2-0.3ml (width of rubber stopper)
Field of Anesthesia: periodontium/soft tissues buccal to molars
Term
Inferior Alveolar (IA)
Definition
Needle: long 25/27 gauge
Penetration Site: medial to internal oblique ridge, lateral to pterygomandibular raphe, at or above height of coronoid notch
Depth of Insertion:2/3 to 3/4 length of needle, until contact with bone, bevel toward bone
Angle of Insertion: 2/3 to 3/4 length of needle, until contact with bone, bevel toward bone
Target: on medial surface of ramus, slightly superior to mandibular foramen
Dose: 1.5-1.8ml
Field of Anesthesia: all teeth in quadrant, all periodontium, buccal mucosa premolars to midline, floor of mouth and 1/2 tongue in quadrant
Term
Mental (M)
Definition
Needle: short 25/27 gauge
Penetration Site: mucobuccal fold at or just anterior to mental foramen
Depth of Insertion: 5-6mm
Angle of Insertion: approximately 20 degrees to long axis of premolars, bevel toward bone
Dose: 0.6ml
Field of Anesthesia: pulpal limited to tooth at site of infiltration, periodontium/soft tissues premolars to midline
