What is the primary goal of maxillary local infiltration?

• A. Pulpal anesthesia of a circumscribed area
• B. Complete maxillary anesthesia
• C. Lingual nerve anesthesia
• D. Surgical removal of bone

Answer: (A)

Maxillary local infiltration is all about targeted, diffusion-based anesthesia of a small, circumscribed area. By injecting near the apex of the tooth, the anesthetic diffuses through the thin, porous maxillary bone to reach the pulp and surrounding periodontal tissues of that tooth or a small group. This yields pulpal anesthesia in a defined region without rendering the entire maxilla numb. It’s not meant to block the entire upper arch or nerves like the lingual nerve, and it doesn’t involve bone removal. So the primary goal is pulpal anesthesia of a circumscribed area.
