Abstract
The aim of the present paper was to highlight the interaction between two composite resins available for dental restorations with artificial saliva in connection with the material properties. The study was focused on specific tribological aspects concerning wear, microhardness of composite material surfaces, friction and lubricant film. The two types of tested materials were composite resins: CERAM-X and FILTEK SUPREME. The experimental researches were based on important laboratory equipment such as microhardness device, metallographic microscope and spectrophotometer. Keywords: composite resins, tribology, wear, microhardness, dental medicine
