Local Anesthesia Injection Sites

Infiltration: Targets individual teeth with injection near the apex.
Anterior Superior Alveolar Nerve Block (ASA): Administers anesthesia to central and lateral incisors and cuspids within one quadrant; injection at mucobuccal fold height near maxillary first premolar.
Middle Superior Alveolar Nerve Block (MSA): Anesthetizes maxillary premolars in one quadrant and the medial aspect of the maxillary first molar; injection at the mucobuccal fold height near the maxillary second premolar.
Posterior Superior Alveolar Nerve Block (PSA): Affects the maxillary second and third molars and the roots of the first molar, including buccal tissues; injection performed at the apex of the second molar directed toward the distobuccal root.
Greater Palatine Nerve Block (GP): Anesthetizes the hard palate and surrounding soft tissues from the distal canine posteriorly; injection made anterior to the greater palatine foramen on the palate near the maxillary second molar.
Nasopalatine Nerve Block (NP): Targets the anterior one-third of the hard palate from canine to canine; injection into lingual tissue adjacent to the incisive papilla.
Maxillary Nerve Block: Anesthetizes buccal, palatal, and pulpal tissues in one quadrant, affecting facial areas like the eyelid, nose, and cheek; injection at mucobuccal fold height above the distal maxillary second molar.
Inferior Alveolar Nerve Block (IA): Covers the mandibular quadrant, including teeth, mucous membranes, and the anterior two-thirds of the tongue; injection within the mandibular ramus, posterior to the retromolar pad, below and anterior to the mandibular foramen.
Buccal Nerve Block: Specifically affects buccal tissues adjacent to mandibular molars; injection made into the mucous membrane distal to the last mandibular molar.
Lingual Nerve Block: Targets lingual tissues and the side of the tongue for mandibular teeth to the midline; injection made along the lingual aspect of the mandibular ramus adjacent to the maxillary tuberosity.
Mental Nerve Block: Affects mandibular premolars and canines, plus adjacent facial tissues; injection performed anterior to the mental foramen between the roots of the mandibular premolars.
Incisive Nerve Block: Targets premolars, canines, and incisors, impacting buccal mucous membrane from the second premolar; injection at the mucobuccal fold height in front of the mental foramen.
