Setting time of Amalgam is best controlled by _______________?
Correct answer: D. Trituration time
- A. Using spherical particles
- B. Lathe cut alloy
- C. Altering Hg-Alloy ratio
- D. Trituration time
Explanation
Trituration is the main clinical method for controlling amalgam’s setting time because it changes the extent and rate of mercury-alloy reaction. Longer or more energetic trituration generally accelerates setting, while inadequate trituration delays or weakens the mix.
