Purpose: This study aimed to investigate if the hardness ratio of bulk-fill-type resin composite is higher than that hybrid-type composite, determine when radiant exposure was same, and polymerization composites at top bottom surfaces affected by differences in irradiance light sources. Methods: The light-curing unit used LED G-Light Prima-II Plus (blue + violet LED) unit. light-cured were Clea...

INTRODUCTION Various bulk-fill materials depending on their composition, viscosity, and flow ability have different physical and mechanical properties. The aim of this in vitro study was to determine and compare the shear bond strength and microleakage properties of activa restorative with other bulk-fill restorative materials surefil (SDR), Biodentine, ever X posterior. MATERIALS AND METHODS...

Aim The aim of this study is to evaluate and to compare the effect of different light-curing modes and different liners on cuspal deflection in premolar teeth restored with bulk filled or incrementally filled composite measured at different time intervals. Materials and Methods The study was divided into two parts (Part 1-different curing modes, Part 2-different liner) each with sixty extract...

OBJECTIVE To study the effect of compositional variables and temperature (25°C and 37°C) on the rheological properties of contemporary resin composites. METHODS Fourteen commercial resin composites with different resin matrices of Bis-GMA and TEGDMA, different filler loading (41-65, v/v) and particle sizes (ranging 5nm to 20μm) were studied using a parallel plate rheometer. Shear sweep measur...

Abstract The objective of this study is to provide a numerical modeling approach for continuous carbon fiber (CCF)-reinforced fused filament fabricated composites. Although these materials have been extensively studied, an effective technique their mechanical performance does not exist. To fill technical gap, based on finite element analysis presented. material properties the Onyx matrix when v...
