Abstract

Many protocols for disinfection can be used to avoid cross-contamination between dental office and dental laboratory. The inclusion of antimicrobial agent to the composition of gypsum or its manipulation with disinfectant substances can be used to this aim. The purpose of this study will be analyse the evaluate the alterations in physical and mechanical propertiesof the natural disinfectants agents incorporated into type IV dental stone (FujiRock EP, GC Europe, Leuven, Belgium.). For evaluate the dental gypsum properties will be realize tests for setting time, reproduction details, setting expansion and compressive tensile, and the morphological alterations will be analyse in a scanning electron microscope.
