Which impression material exhibits the greatest mucostatic properties?

Show Answers

A diluted mixture of plaster of ParisImpression paste made from zinc oxide eugenolSoft, easily spreadable waxHydrocolloids that can be reversed

Explanation

Option A, a thin mix of plaster of Paris, is known for its mucostatic characteristics, meaning it minimally displaces the mucosa during impression taking. The other materials, such as zinc oxide eugenol paste, free-flowing wax, and reversible hydrocolloids, do not provide the same level of mucostatic effect.
