What happens if alginate dries out before the gypsum is poured?

Question

Quizplus · Accepted Answer

If alginate dries out before gypsum is poured, it will absorb water from the gypsum and cause the gypsum to have less water available for proper setting. This can result in a distorted impression. Additionally, the edges of the alginate may tear off, further distorting the impression. Therefore, options A and C are the correct choices. Option B is a possible consequence, but it is not as significant as the other two. Therefore, the best choice is E, as it includes the two most significant consequences.
