Abstract Objectives To determine the effects of various monomers on conversion and cytocompatibility of dental composites and to improve these properties without detrimentally affecting mechanical properties, depth of cure and…
Highlights • 10% Strontium acetate increased nanomechanical properties of demineralized dentin. • Strontium acetate increased tubule occlusion for normal and demineralized dentin. • Brushing with strontium was better in recovering…
Abstract Objective To evaluate the ability of thio-urethane oligomers to improve the properties of restorative composite resins. Methods Oligomers were synthesized by combining 1,6-hexanediol-diissocyante (aliphatic) with pentaerythritol tetra-3-mercaptopropionate (PETMP) or…
Highlights • We evaluated the use of EDC cross-linking to maintain dentin bond durability in artificial saliva. • EDC cross-linking had no effect on the fatigue crack growth resistance immediately…
Abstract Objective To compare a shear bond strength test for resin composite cements developed in order to better consider the shrinkage stress (here termed “Swiss shear test”) with the shear…
Abstract Objectives To develop two experimental temporary crown and bridge materials with improved physicomechanical properties. Methods Commercial materials: Trim (TR, monomethacrylate, Bosworth) and Quicktemp2 (QT, dimethacrylate, Schottlander). Experimental materials: isobutyl…
Highlights • We evaluated the ability of a cross-linking agent (EDC) to improve the stability of demineralized dentin. • Demineralized dentin matrix underwent static or dynamic (chewing simulation) aging to…
Abstract Objectives The purpose of this study was to assess surface and subsurface damage on 4 CAD-CAM high-strength ceramics after grinding with diamond disks of 75 μm, 54 μm and…
Highlights • Color and translucency of model composites were affected primarily by the type of monomer. • Color stability was greatly affected by monomer and to a lesser extent by…
Abstract Resin bonding to dentin requires the use of self-etching primers or acid etching to decalcify the surface and expose a layer of collagen fibrils of the dentin matrix. Acid-etching…
