The PSA nerve block primarily anesthetizes which region?

Explanation:
The posterior superior alveolar nerve block targets the posterior superior alveolar nerve, which supplies the maxillary molars. Because this nerve carries sensation from the molar region (and the overlying buccal gingiva, with possible involvement of the maxillary sinus), the block primarily anesthetizes the maxillary molars. The maxillary anterior teeth are supplied by the anterior superior alveolar nerve, and the mandibular teeth by the inferior alveolar nerve, so a PSA block does not primarily numb those areas. Premolars may be affected variably depending on anatomical variation, but the main region iced by this block is the molar area.
