Tarnish resistance evaluation of experimental Pd-free Ag-Au-Pt-Cu dental alloys
Dental alloys Tarnish resistance Discoloration
2010/11/29
This study evaluated the tarnish resistance of eight experimental Pd-free Ag-Au-Pt-Cu dental alloys in a 0.1% Na2S aqueous solution at 37°C. Color measurements of the plate samples were made using a c...
This study compared the resistance to removal by traction of abraded cylindrical metal cast posts of Cu-Al (Goldent-LA). The posts had constant length (9 mm) and three different diameters (0.9, 1.3 an...
