Comparison of cutting efficiencies between electric and ...
2010-2-1u2002·u2002Results. The electric handpiece cut more efficiently than the air-turbine handpiece (F=3098.9, P<.001).In particular, the high noble metal alloy, silver amalgam, and Macor were cut more efficiently with the electric handpiece (0.0383 ±0.0002 g/s, 0.0260 ±0.0002 g/s, and 0.0122 ±0.0002 g/s, respectively) than with the air-turbine handpiece (0.0125 ±0.0002 g/s, 0.0142 ±0.0002 g/s, and 0.008 ...
