Light transmission through different resin-matrix composites and cements under polymerization as performed in dental practice

Description

Purpose: The purpose of present thesis was to evaluate the light transmittance through traditional and flowable resin-matrix composites containing different amount of inorganic fillers as well as the light transmittance through resin-matrix onlays cemented with resin cements and flowable resin-matrix composites.
Conclusions: A high content inorganic fillers decreased the light transmittance through resin-matrix composites. On onlays the optical transmittance highly decreases when onlays thickness increases. Also, the materials’ microstructure highly affects the optical transmittance through the onlays and luting materials. The type, size, and content of inorganic fillers of the luting material affected the thickness of the cement layer and light transmittance through the materials. However, certain types of fillers do not interfere the light transmission maintaining an optimal polymerization and the physical properties of the resin-matrix composites.
