How should polycarboxylate cement appear after it is mixed?

  1. Opaque

  2. Glossy

  3. Matte

  4. Translucent

The correct answer is: Glossy

Polycarboxylate cement should appear glossy after it is mixed because it contains a high percentage of water, giving it a smooth, wet appearance. The other options are incorrect because A Opaque would indicate a lack of water or possibly contamination, C: Matte would indicate a gritty, rough texture, and D: Translucent would indicate that the cement is not fully mixed or contains air bubbles. A glossy appearance is important in polycarboxylate cement as it indicates proper mixing and ensures good bonding and strength.
