Rough and irregular surface produced on the impression is because of ?
Correct answer: C. Too rapid polymerization
- A. Improper application of pressure during impression making
- B. Air incorporated during mixing
- C. Too rapid polymerization
- D. Presence of moisture in impression area
Explanation
If an impression material polymerizes too rapidly, it cannot flow and adapt smoothly to the oral tissues, producing a rough or irregular surface. Air incorporation mainly produces localized voids or bubbles rather than a uniformly rough surface.
