Which type of amalgam is easier to condense and better around pins?

Spherical
Admixed
Gamma 1
Beta

The correct answer is: Spherical

Spherical amalgam is the best choice for condensing and shaping around pins for several reasons. Spherical amalgam has a smooth and round shape which allows for easier condensing and shaping. Due to its ball-like shape, spherical amalgam also has better flow and adaptability, making it easier to fill small spaces around pins. On the other hand, admixed amalgam has a mix of different particle shapes which can make it more difficult to condense and shape around pins. Gamma 1 amalgam has a flaky and irregular particle shape which can also make it challenging to condense and shape, while beta amalgam has a rough and angular particle shape that can make it difficult to flow and adapt. Therefore, spherical amalgam is the best choice for these specific needs.
