Which instrument is used to pack amalgam into cavity preparations?

1. Carver

2. Spoon Excavator

3. Amalgam Condenser

4. Gingival Margin Trimmer

The correct answer is: Amalgam Condenser

The amalgam condenser is specifically designed for packing amalgam into cavity preparations. This instrument has a smooth, flat end that allows the dental professional to compress amalgam material into the cavity, ensuring that it fills the space securely and adequately. Proper condensation of the amalgam is critical to achieve the desired density and to minimize the risk of voids that could compromise the restoration's longevity and effectiveness. In contrast, other instruments serve different functions in dental procedures. A carver is used for shaping and contouring the surface of the amalgam after it has been placed, but it does not pack the material into the cavity. A spoon excavator is utilized for removing decayed tooth material, and while it may assist in preparation, it is not designed for packing amalgam. The gingival margin trimmer helps in finishing and refining the margins of a cavity preparation but, like the others, it does not pack the amalgam into the cavity. Therefore, the amalgam condenser is the appropriate instrument for this specific task.
