Abstract
Romanian researchers, both dentists and engineers, are continuously involved to develop the knowledge concerning applications of different types of materials in restorative dentistry [1-4]. Only thus there is possible to be solved the main complex and interdisciplinary aspects targeting this large class of materials. Hence the present paper is focused on experimental studies of three glass ionomers taking into account their tribological behaviour in oral cavity under specific conditions. Keywords: glass ionomers, tribology, corrosion, restorative materials, dentistry
