Which dental procedure does NOT generally require an infraorbital nerve block?

The extraction of mandibular incisors does not generally require an infraorbital nerve block because this procedure pertains to the lower jaw, specifically the mandible. Local anesthesia for lower teeth, such as mandibular incisors, typically involves using a technique focused on the inferior alveolar nerve, which supplies sensation to the lower teeth and the surrounding structures. The infraorbital nerve block, on the other hand, is primarily used for dental procedures involving the upper jaw or maxilla, where it provides anesthesia to the anterior teeth and adjacent tissues.

In contrast, the other procedures listed, including the extraction of maxillary central incisors, restoration of maxillary molars, and endodontic treatment on maxillary premolars, are performed in the upper jaw, thus necessitating an infraorbital nerve block to ensure adequate pain control and numbness in that area.
