In-vitro study: the effect of plasticity, time of condensation upon surface roughness of some amalgam alloys

ABSTRACT

The present work was performed to evaluate the role of some variables that mayaffect the surface roughness of dental amalgam. Three different types ofcommercial amalgams were used in this study. The combination of variablesincluded in this work were plasticity of the triturated mix, and time elapsingfrom the end of trituration up to start of condensation. The results showedthat the surface roughness of the investigated amalgams was affected markedlyby the studied variables
