Finishing and polishing of Amalgam make the restoration______________?
Correct answer: A. Increase in tarnish and corrosion resistance
- A. Increase in tarnish and corrosion resistance
- B. Increase the marginal strength
- C. Decrease the tarnish and corrosion resistance
- D. Increased compressive strength
Explanation
Finishing and polishing smooth the amalgam surface, removing rough areas that retain plaque and promote electrochemical attack. This improves resistance to tarnish and corrosion and can also improve marginal adaptation, but the best listed answer is increased tarnish and corrosion resistance.
