Abstract

summary The effect of an Ag–Cu–Pd dispersant alloy on the structure of amalgams fabricated with two different particle types of low‐copper amalgam matrices was investigated. In amalgams L and L (0), a low‐copper lathe‐cut amalgam Aristalloy® was used as the matrix. In amalgams S and S(0), the matrix used was Spheralloy®, a low‐copper spherical amalgam. X‐ray diffraction was used to analyse the relative content of the phases in the amalgams. The presence of Pd in the dispersant of amalgams L and S resulted in a decrease in the amount of η′(Cu6Sn5) and an increase in the amount of unreacted particles when compared to the controls L(0) and S(0). Amalgams fabricated with a spherical alloy matrix (S and S(0)) showed a greater effect than amalgams fabricated with a lathe‐cut matrix alloy (L and L(0)).
