Properties of dual-cure, bulk-fill composite resin restorative materials.
The purpose of this study was to compare the properties of 2 new dual-cure, bulk-fill restorative composite resins to those of a hybrid composite resin material. Depth of cure, fracture toughness, porosity, microleakage, and volumetric shrinkage properties were examined. With the exception of fracture toughness, significant differences were found among materials. Compared to the incrementally p...
متن کاملBulk Fill Composite Resins . A Novelty in Resin - Based Restorative Materials
Composites resins are the most popular restorative materials providing very good esthetics and long period of good clinical performance. Depth of cure of composite resins is crucial in determining the maximal increment thickness when restoring tooth cavities. In restorations with conventional composite resins the thickness of each increment has been defined as up to 2 mm. Bulk fill composite re...
متن کاملRelative Microhardness and Flexural Strength of Different Bulk Fill Resin Composite Restorative Materials
Aim: to find out if there is a significant difference in the curing efficiency at the claimed 4 mm depth and in the mechanical properties between the tested pasteform bulk fill resin composite materials. Materials and Methods: Three paste-consistency bulk-fill resin composites were used in this study (Filtek bulk fill3M; X-trafilVoco; and SonicFill bulk-fillKerr). For the microhardness testing,...
متن کاملArgon-Ion Laser Vs Quartz-Tungsten-Halogen Curing of Polyacid Modified Composite Resin Restorative Materials
Recently, there has been an interest in using an argon laser to initiate polymerization of light-activated materials [11]. The argon laser, the active medium of which is argon gas, produces light at two wavelengths. The 488 nm blue light is commonly used to initiate the polymerization of restorative composite materials. The 514 nm blue green light has maximum absorbance in tissues that are comp...
متن کاملConsiderations Regarding the Optical Properties of the Composite Resin Restorative Materials
The purpose of this study has been to investigate the effects of certain substances frequently used in alimentation on the color stability of the composite resin restorative materials. The research hypothesis was that color stability of the composite resin is affected by the type of composite material used and by the polishing procedure. 14 samples of 5X15X2mm have been prepared from seven univ...
