What causes a rough and uneven texture on an impression surface?

Show Answers

Air trapped while mixing the materialIncorrect pressure applied during the impression processExcessive saliva contamination in the impression areaIncorrect proportion of polymer to monomer

Explanation

A rough and irregular surface on an impression typically results from an incorrect polymer to monomer ratio, which affects the material's setting and texture. Other factors like air entrapment, improper pressure, or saliva contamination can cause defects but not this specific roughness.
