What result does over trituration have on the amalgam mix?

Over-trituration of an amalgam mix leads to a dry mix because the excessive mixing causes the amalgam particles to become excessively compacted. This results in a reduction of the amount of mercury available to wet the alloy particles, leading to a mix that lacks the appropriate moisture content for optimal workability.

In this state, the amalgam becomes less cohesive and more difficult to manipulate or condense properly into a cavity preparation. A dry mix also may result in a loss of strength and an increase in the brittleness of the set material. Proper amalgamation is critical to achieve the right balance between the alloy and mercury; over-trituration disrupts this balance and compromises the overall physical properties of the material.
