Abstract
Four new dental composites with different inorganic phases were submitted to comparative study regarding their structure,
compressive strength, diametral tensile strength, flexural strength and Vickers hardness, as well as composite-hard tissue
interface. The composites containing bioceramic show the best integration of silanized filler into the organic matrix. SEM
analysis reveals the development between tooth and composite material of a continuous interface consisting in a zone that
is different from both bonding resin and dentine. The results of this study prove the effects of filler composition on
mechanical properties of the composite resins, and at the same time on the interface between composite and tooth hard
tissues.
