Abstract:
In recent years, there have been many attempts to improve the properties of dental amalgam. The primary
constituents are Ag, Sn, Cu, and sometimes Zn which were traditionally carefully chosen for certain specific
characteristics. In this work, however, (0.5-1) % ZnO and TiO2 were added separately and together. The addition
was added to amalgam alloy powder and the prepared composite powder was triturated by a given percent of
mercury. Wear test was performed with presence artificial saliva and conducted by Pin-on-Disc. Vickers hardness
and compression strength was also conducted. The results showed that amalgam/ TiO2 composite and amalgam/
hybrid composite posses the best wear resistance (85% compared to the control specimen), hardness (48% and 47%
respectively with respect to the control specimen) and compression strength (63% and 62.5% respectively with
respect to the control specimen).
