What instrument is used to carve amalgam on the occlusal surface of a tooth?

The correct instrument for carving amalgam on the occlusal surface of a tooth is the discoid/cleoid. This instrument has two distinct sides: one side is discoid-shaped, which is used for carving and shaping the occlusal surface of the restored tooth, and the other side is cleoid-shaped, which allows for the fine detailing of the restoration.

Carving amalgam accurately is crucial for ensuring proper occlusion and function after the filling is placed. The design of the discoid/cleoid allows for precise manipulation of the amalgam material, enabling the dental assistant or dentist to create the correct anatomy and contours necessary for effective biting and chewing.

Other instruments listed, such as the excavator, condenser, and burnisher, serve different purposes in dental procedures. The excavator is typically used for removing decay or debris from the tooth structure, the condenser is used to pack the amalgam into the cavity preparation, and the burnisher is used to smooth the surface of the amalgam or other restorative materials. Each instrument has its specific role, making the choice of the discoid/cleoid the suitable option for carving the occlusal surface of an amalgam restoration.
