Which of the following is true regarding the effect of filler particles on composite polishability during finishing and polishing?
Show answer and explanation
Correct answer: Harder fillers can protrude as the matrix wears, raising roughness
During polishing, the softer resin matrix may abrade faster than harder filler particles, which can protrude and increase roughness if not properly polished. Good technique balances this effect.
