What is the characteristic appearance of properly triturated amalgam?

1. Glossy

2. Satiny

3. Dull

4. Rough

The correct answer is: Satiny

The distinctive characteristic appearance of properly triturated amalgam is satiny. When amalgam is mixed correctly, it achieves an ideal consistency that allows it to possess a smooth and slightly reflective surface, which is described as a satiny finish. This appearance is crucial as it indicates that the amalgam particles are well-blended, allowing for optimal properties in terms of adaptation, strength, and longevity once placed in the cavity preparation. A glossy appearance is often an indication of over-trituration, where the amalgam becomes too smooth and may lose some of its desirable qualities, including the ability to bond effectively with the tooth structure. A dull appearance, while it may seem acceptable, can reflect under-trituration, resulting in a less cohesive and weaker amalgam. Lastly, a rough surface would suggest inadequate mixing or the presence of excess moisture, leading to a compromised material structure that is not suitable for dental restoration.
