Abstract Objectives To critically appraise experimental ex vivo research that has focused on secondary caries, and to offer possible explanations for the seemingly poor correlation to clinical observations. Methods The…
Abstract Objectives The objective of this article is to discuss the evidence for polymerization shrinkage and shrinkage stress of dental composite restoratives in terms of its potential relevance to the…
Highlights • Processes responsible for the degradation of resin-bonded interfaces are described. • Durability of the resin–dentin bond strength may be improved by inhibiting intrinsic collagenolytic activity. • Cross-linking agents…
Abstract Objectives The purpose of this study was to determine the dentin bonding ability of three new universal adhesive systems under different etching modes using fatigue testing. Method Prime &…
Highlights • Calcium silicate-based sealer using water and propylene as vehycle were assessed. • All prototype sealers prodeuced clacium hydroxide during hydration and favored alkaline pH and calcium release. •…
Abstract Objectives To evaluate marginal adaptation, fracture load and failure types of CAD/CAM polymeric inlays. Methods Standardized prepared human molars (48) were divided into four groups ( n = 12):…
Abstract Objectives To test the tensile bond strength (TBS) between two self-adhesive resin composite cements and PEEK after helium plasma treatment and used glycine as a potential coupling agent incorporated…
Abstract Objective The aim of this study was to evaluate the effect of TiO 2 concentration on the properties of apatite-mullite glass-ceramics namely strength and the chemical solubility to comply…
Graphical abstract Highlights • Bulk fracture is a primary reason for resin-based dental restoration failures. • Self-healing resin contained microcapsules with TEGDMA-DHEPT healing liquid. • A self-healing efficiency of 65%…
Abstract Objectives Calcium phosphate (CaP) composites with Ca and P ion release can remineralize tooth lesions and inhibit caries. But the ion release lasts only a few months. The objectives…
Highlights • We characterize optical and mechanical properties of enamel surfaces during erosion and remineralization. • 3D imaging of enamel surfaces undergoing erosive wear requires instrumentation with lateral resolution significantly…
Highlights • Developed a novel injectable cell delivery system based on iPSMSC encapsulation in microbeads in a CPC paste. • The first report on cranial bone reconstruction using self-setting microencapsulated…
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…
