Identify the Couplands Chisel.

• A. Scalpel
• B. Dissecting Forceps
• C. Couplands Chisel
• D. Periosteal Elevator

Answer: (C)

The key idea is matching an instrument to its specific surgical use. Couplands Chisel is the bone-cutting tool in oral surgery. It has a flat, bevel-edged blade designed to cut, split, or plane bone when access to the tooth or supporting bone is needed, often used with controlled tapping or manual pressure. This contrasts with a scalpel, which is for soft-tissue incisions; dissecting forceps, which grasp and hold tissue; and a periosteal elevator, which lifts the periosteum away from bone. Because its primary job is cutting bone rather than incising tissue, removing tissue, or elevating periosteum, it is the instrument described as Couplands Chisel.
