OBJECTIVES The purpose of this study was to enhance curing light penetration through resin inlays by modifying the thicknesses of the dentin, enamel, and translucent layers. MATERIALS AND METHODS To investigate the layer dominantly affecting the power density of light curing units, resin wafers of each layer with 0.5 mm thickness were prepared and power density through resin wafers was measur...

fiber post (GFP) treated or not with phosphoric acid, silane coupling agent, and unfilled resin. GFPs were etched or not with 37% phosphoric acid and different surface coating applied: silane coupling agent, unfilled resin, or both. Composite resin blocks were built around a 4-mm height on the GFP. Unfilled resin (20 s) and composite resin (40 s) were light activated by a light-emitting diode u...

Resin is a chemical and physical defensive barrier secreted by many plants, especially coniferous trees, with insecticidal and antimicrobial properties. The degradation of terpenes, the main components accounting for the toxicity of resin, is highly relevant for a vast range of biotechnological processes, including bioremediation. In the present work, we used a resin-based selective medium in o...

in this study, the corrosion resistance of a bituminous coating reinforced with different ratios ofnanoclay pigment was studied. to make nanocomposite coatings, 2, 3, and 4 wt.% of clay (cloisitena+) were incorporated into water emulsified bitumen. the coatings were applied to steel 37. opticalmicroscopy and x-ray diffraction (xrd) were used to characterize the nanocomposite structure. inorder ...
