The biocompatibility of three kinds of Pd-Co dental casting ferromagnetic alloys was assessed in a toxicity test in vitro. The test showed that the Pd-Co binary alloy may have weak cytotoxicity, while the Pd-Co-Cr and Pd-Co-Ni ternary alloys may be less cytotoxic. The Pd-Co-Ni alloy was least cytotoxic of the three.
