During an injection, how should the bevel of the needle be oriented relative to the bone?

• A. Toward the bone
• B. Toward the mucosa
• C. Parallel to the mucosa
• D. Away from the bone

Answer: (A)

Bevel toward the bone. When the sharp edge of the needle faces the bone as you enter, it cuts the soft tissue in a clean, narrow path rather than tearing it. This minimizes tissue trauma, reduces pain and bleeding, and helps keep the needle on a stable, straight track as you advance to the bone. If the bevel faces mucosa or runs parallel to it, the edge is more likely to tear tissue and cause more discomfort, and it can lead to a less controlled entry near the bone.
