Abstract: Princalloy is a new dental amalgam alloy introduced into the Saudi market by SADIN Saudi Production Company. It is claimed by the manufacturer that Princalloy is a high copper gamma-2 free, Saudi-made amalgam. The aim of this study was to evaluate Princalloy powder/liquid ratio, particle shape and size, composition and microhardness, and compare it with other commonly-used dental amalgam Tytin and Dispersalloy. Samples were prepared using stainless steel die and plungers according to ADA specification No. 1. All specimens were burnished before stored in a dry chamber at 370C. For microhardness, evaluation measurements were performed after one hour, one, three and six days from trituration time. Hardness measurements were conducted under 500 gm load for 10 seconds using Vickers Microhardness, Buehler Micromet II. Samples surfaces were metallographically polished and etched before examination under light microscope, Polyver Met (Rochert-Jung) and SEM/EDXA (JSM-T300, operated at 25 kv) for composition and surface analysis. Princalloy powder consisted of spherical, irregular spherical, tear-shaped and smashed spherical particles with maximum particle size of < 21.6 ± 1.84 um Tytin < 16.7 ± 1.03 umand Dispersalloy < 42.1 ± 6.17 um. Powder/liquid ratio of Princalloy showed 1:0.96 which is higher than Tytin (1:075) and less than Dispersalloy (1:1.05). Microhardness results of Princalloy was the highest and significantly higher than Tytin and Dispersalloy after one hour from trituration time.EDXA spectroanalysis of the amalgam particles have essentially the same spectra since they are all representing high copper amalgam alloys, therefore the same elements (Ag, Gu, Sn) are their main components. Princalloy and Dispersalloy have higher Cu content (50%) approximately more than Tytin.
