New selenium-containing silver amalgam.
An investigation was made to determine the effects of the addition of selenium to the silver-tin amalgam alloy. The addition of 0.2 wt% to 0.6 wt% selenium in the alloy completely eliminated the cytotoxicity, evaluated by the 51Cr release assay and morphology, of the silver amalgam on the L cells and JTC-12 cells. The physical properties of the amalgam containing 0.2 wt% selenium in the alloy were tested according to the American Dental Association Specification No. 1 for Alloy for Dental Amalgam and were found to meet the requirements.
