The higher the Hg alloy ratio in dental amalgam________________?
Correct answer: C. More matrix matrial formed
- A. Higher the strength
- B. Lower the creep value
- C. More matrix matrial formed
- D. More gamma 1 phase formed
Explanation
A higher mercury-to-alloy ratio leaves more unreacted mercury available to form the matrix, including mercury-rich reaction products. Excess matrix generally lowers strength and increases creep rather than improving the restoration.
