Abstract
Manual, pneumatic, electromagnetic, belt-driven, and ultrasonic compaction methods were compared on the basis of transverse strength and microstructure of 100 specimens of spherical alloy dental amalgam. Specimens were tested 1 hour and 24 hours after compaction. Belt-driven compaction was significantly better than the other 4 methods at 1 hour with a mean transverse strength of 5,240 p.s.i. No significant difference was found among the higher strengths of the 24 hour specimens. Microscopic examination revealed typical fracture patterns and porosity characteristics.
