Question 1. Define and classify silver amalgam alloy. 
Answer:

Silver amalgam alloy is an alloy that is made by mixing mercury with silver tin alloy to which varying amounts of copper and a small amount of zinc are added.

Question 2. Write a short note on the importance of condensation of silver amalgam.
Answer:

Condensation is a process by which the mix is compacted into a prepared cavity to attain a dense mass.

Following is the importance of condensation of silver amalgam:

• It helps in the development of a continuous matrix.
• It helps in the removal of excess mercury and minimizes porosity.
• It helps in the proper adaptation of silver amalgam to all parts of cavity walls and margins, thereby increasing retention and minimizing microleakage.
• Helps in the better adaptation of incremental layers of amalgam.
• Proper condensation increases the strength of silver amalgam by bringing the strongest phases of amalgam close together.
• It decreases the creep of silver amalgam.
