Show answer and explanation
Correct answer: Aluminum-oxide polishing paste with a soft rubber cup
Aluminum-oxide polishing pastes applied with a soft rubber cup are standard for final surface gloss and smoothness on restorations. Diamond or steel burs are too abrasive for final polish; sandblasting isn’t used clinically for final polish.
