Which of the following metals is NOT a component of dental amalgam?

Gold is not a component of dental amalgam. Dental amalgam is a restorative material commonly used in dentistry, composed primarily of metals such as silver, mercury, and tin. Silver and tin contribute to the strength and durability of the amalgam, while mercury serves as the binding agent that holds the other metals together, enabling them to form a workable paste that hardens upon setting.

The absence of gold from dental amalgam is significant because gold is typically used in dental restorations in the form of gold alloys, which are distinct from the amalgam compositions. Gold alloys are utilized for their excellent strength, biocompatibility, and aesthetic properties, but they do not participate in the amalgam mixture.

This distinction is crucial for dental professionals, as understanding the composition of materials ensures appropriate selection for different restorative situations.
