Experimental evaluation of different fillers in dental composites in terms of mechanical properties

The aim of this study was to evaluate in vitro the influence of nano-sized filler particles and agglomerates of nano particles (nano cluster) in resin based dental composite material. Four commercially available resins based dental composites-Filtek Z250, Filtek Supreme, Filtek Z100 (3M ESPE, St Paul, MN, USA), Heliomolor (Ivoclar Vivadent, Schaon, Liechtenstein) containing different filler particle type and morphologies were investigated. The compressive strength, compressive modulus, flexural modulus and flexural strength of these composites were evaluated.
