Test samples of five different dental alloys were prepared in discs 10 mm in diameter and 1.5 mm thick. Their surfaces were sandblasted, ground with sand paper, polished and electrolyzed in succession. 10 samples of each alloy in each surface finishing were prepared Surface roughness of each disc was determined by the use of a profilometre. The adsorption of the surfaces was measured by 99mTc-MDP both before and after 2 h of exposure to oral environment. The results indicated that the discs sandblasted and electrolyzed had the maximum and those polished the minimum surface roughness. The adsorption showed variation according to surface roughness and to the alloy type prior to exposure to oral environment. Alloy samples with different surface roughness placed in the oral cavity exhibited similar adhesive properties.
