In this study, the clinical performance (marginal fracture) of a gold-containing amalgam was compared to five traditional γ2-containing amalgams and one non-γ 2 amalgam. The results showed that the performance of this gold-containing amalgam was bettered by the non-γ2 amalgam and four of the five γ2-containing amalgams. A microprobe evaluation of a five-year-old clinical restoration made from this alloy revealed an unusual corrosion pattern.
