Polishing agents for amalgam are to be wetted
1) To reduce frictional heat
2) To increase the action of the polishing agents
3) To prevent dehydration of the tooth structure
4) All of the above

Conservative Dentistry Answer: 1

The main purpose of a gingival bevel in an inlay or onlay is
1. Improves the retention form of the cavity
2. Improves the resistance for of the cavity
3. Removes unsupported enamel and compensates for the casting shrinkage
