Abstract

The metallic particles contained in the powder of 26 alloys for dental amalgams and 3 gallium alloys were analysed by means of a laser particle meter. The measured parameters included the maximum and minimum size, the mean value and the percentiles 10 and 90 of the distribution. The results showed that the lathe-cut amalgams present wider distribution ranges than the rest of the amalgams, the spherical amalgams registered a smaller distribution and the amalgams of dispersed or mixed morphology an intermediate distribution. All the amalgams showed a tendency toward small particle sizes.
