The purpose of this project was to determine the amalgam surface roughness following finishing and polishing procedures. Nine high-copper amalgams were tested. They were hand-condensed in a 3 x 3 x 30 mm mold. Each sample was divided into four sections, and each section was finished by one of four methods: carving only; carving and then burnishing 15 minutes after carving; carving and then polishing at the prescribed times; or carving, burnishing 15 minutes after carving, and then polishing at the prescribed times. Each bar of amalgam had these surface treatments done at either 1, 3, 6, or 24 hours. The results indicated surface roughness may be more dependent on particle size, shape, and distribution of the individual high-copper amalgams than the polishing time or the surface treatment performed.
本项目的目的是确定完成修整和抛光程序后汞合金的表面粗糙度。测试了九种高铜汞合金。它们在3×3×30毫米的模具中手工压实。每个样品被分成四个部分，每个部分通过以下四种方法之一进行处理：仅雕刻；雕刻后15分钟进行打磨；在规定时间进行雕刻和抛光；或雕刻、雕刻后15分钟进行打磨，然后在规定时间进行抛光。每个汞合金棒在1、3、6或24小时进行这些表面处理。结果表明，表面粗糙度可能更多地取决于各个高铜汞合金的颗粒大小、形状和分布，而不是抛光时间或所进行的表面处理。
