What is the effect of increasing the mercury content in a dental amalgam alloy?

Show Answers

Increases the overall strengthDecreases the creep resistanceResults in a greater amount of matrix material formationLeads to a higher proportion of the gamma 1 phase

Explanation

Increasing the mercury ratio in dental amalgam causes more matrix material to form, which affects the amalgam's properties. This change is distinct from strength, creep values, or the amount of gamma 1 phase present.
