Influence of light-exposure methods and depths of cavity on the microhardness of dual-cured core build-up resin composites
OBJECTIVE The purpose of this study was to evaluate the Knoop hardness number (KHN) of dual-cured core build-up resin composites (DCBRCs) at 6 depths of cavity after 3 post-irradiation times by 4 light-exposure methods. MATERIAL AND METHODS Five specimens each of DCBRCs (Clearfil DC Core Plus [DCP] and Unifil Core EM [UCE]) were filled in acrylic resin blocks with a semi-cylindrical cavity an...
متن کاملEffect of curing mode on the hardness of dual-cured composite resin core build-up materials.
This study evaluated the Knoop Hardness (KHN) values of two dual-cured composite resin core build-up materials and one resin cement exposed to different curing conditions. Two dual-cured core build-up composite resins (LuxaCore-Dual, DMG; and FluoroCore2, Dentsply Caulk), and one dual-cured resin cement (Rely X ARC, 3M ESPE) were used in the present study. The composite materials were placed in...
متن کاملcomparative depth of cure among two light-cured core build-up composites by surface vickers hardness.
depth of cure of composite material is restricted and it depends on many parameters such as thickness. the aim of this in-vitro study was to evaluate the depth of cure of two light-cured core build-up composites (quixfil and photocore) in different thicknesses, when cured for 60 seconds.the vickers microhardness measurements were made for each side of the top irradiated surfaces of 1,2,3,4,5,6,...
متن کاملInfluence of the interaction of light- and self-polymerization on subsurface hardening of a dual-cured core build-up resin composite.
OBJECTIVE To investigate the influence of time delay and duration of photo-activation on subsurface microhardness of a dual-cured resin composite. MATERIAL AND METHODS A commercially available dual-cured core build-up resin composite (Rebilda DC) was filled in cavities (diameter: 4.0 mm; height: 6.0 mm) of polystyrene molds and light-cured for 20 or 60 s either immediately after the filling p...
متن کاملPolymerization shrinkage, flexural and compression properties of low-shrinkage dental resin composites.
This study evaluated the polymerization shrinkage, flexural and compressive properties of low-shrinkage resin composites. For the study, four methacrylate-based and one silorane-based resin composites were light cured using three different light-curing units (LCUs) and their polymerization shrinkage, flexural (strength (FS) and modulus (FM)) and compressive (strength (CS) and modulus (CM)) prop...
