Higher rates of alginate deformation result in higher compressive and tear strengths.Alginate impressions are more likely to tear during removal from the mouth when they are removed rapidly.

Question

Quizplus · Accepted Answer

The first statement is true as higher rates of alginate deformation (i.e. the rate at which the material is compressed) result in higher strength properties of the material. The second statement is false as alginate impressions are more likely to tear during removal when they are removed slowly, not rapidly. This is because slow removal allows for water absorption, which weakens the material and makes it more prone to tearing.
