How much is typically injected for palatal infiltration?

• A. 0.5 ml
• B. 1.0 ml
• C. 0.2-0.3 ml
• D. 2.0 ml

Answer: (C)

Palatal infiltration uses a very small volume because the palatal mucosa is dense and tightly bound to the underlying bone. A small amount is enough to bathe the nerve endings in that localized area without creating much tissue distortion or pressure, which can be painful and risky in the tightly packed palate. Using larger volumes can cause unnecessary pressure, increase discomfort, and may spread beyond the target area. In practice, about 0.2–0.3 mL per injection site is typically sufficient to achieve palatal anesthesia.
