Does longer amalgam trituration increase or decrease strength?

Increases
Decreases
Has no effect
Initially increases then decreases

The correct answer is: Decreases

Trituration is the process of mixing dental amalgam to achieve the desired consistency and properties. In general, the longer amalgam is triturated, the weaker its final strength will be. This is because extended trituration leads to the incorporation of more air into the mixture, resulting in increased porosity and decreased strength. Options A and D are incorrect because they suggest that longer trituration results in increased strength, which is not the case. Option C is incorrect because trituration does have an effect on the strength of amalgam. It is important for dental professionals to carefully follow recommended trituration times to achieve the best results.
