Abstract Objectives Bioactive glass forms a bone mineral apatite interface and can be engineered to promote optimal bone regeneration. Strontium (Sr 2+ ) stimulates osteoblast and inhibits osteoclast activities in…
Highlights • Grinding increases the ceramic’s resistance towards ageing at the subsurface. • The activation energies compares well with previous reported values. • After aging at 37 °C, predicted and…
Graphical abstract Highlights • MDP containing universal adhesive alone provides effective chemical bonding to Y-TZP. • Silica coating + silanization provided higher hydrolytic stability than applying MDP. Abstract Objectives To…
Highlights • Demineralization of dentin causes a decrease in the surface free energy. • Acetone added to a nano-HA solution increases the surface wetting of dentin. • Acetone facilitates the…
Highlights • XFEM results were in good agreement with those of the experimental results. • XFEM enabled us to capture a more accurate load at first sign of a crown’s…
Graphical abstract Highlights • Application of photo-catalytic activities of TiO 2 NPs could be tuned through dental resins. • Adding TiO 2 NPs in hydroxyl-rich resins may produce materials with…
Abstract Objectives Recently several zirconia primers have been introduced to mediate bonding of dimethacrylate resins to yttria-stabilized zirconia frameworks (Y-TZP). The aim of the study was to evaluate the changes…
Abstract Objectives The literature reports inconsistent results regarding using configuration factor (C-factor) as an indicator to reflect the generation of polymerization shrinkage stress (PS) from dental restorative composites due to…
Abstract Objective Acids, such as those used in adhesive dentistry, have been shown to solubilize bioactive molecules from dentin. These dentin matrix components (DMC) may promote cell proliferation and differentiation,…
Highlights • Fluoride from dental materials works on caries similarly as fluoride from dentifrices. • The effect of fluoride from dental materials is based on in vitro and in situ…
Graphical abstract A different approach has been adopted to form highly branched polyacrylic acid (PAA) copolymers based on octavinyl polyhedral oligomeric silsesquioxane (octavinyl POSS). t -butyl acrylate star polymers with…
Graphical abstract Highlights • GeO 2 increased the degradability of 0.48- xSiO 2 , xGeO 2 , 0.36ZnO, 0.16CaO glasses. • Increased GeO 2 reduced initial GIC viscosity and slowed…
Abstract Objectives Adhesion on dentin is less reliable than on enamel, which could affect the durability of laminate veneers (LV). Immediate dentin sealing (IDS) is suggested instead of delayed dentin…
Abstract Background and objectives Current clinical methods for diagnosing secondary caries are unreliable for identifying the early stages of decay around restorative materials. The objective of this study was to…
Abstract Objective This paper investigates the photo-co-polymerization behavior of a blend of a diacrylamide (DEBAAP) with a phosphonylated acidic monomer using either bis(acyl)phosphine oxide or camphorquinone/amine as photo-initiator and studies…
Abstract Objective To use a compliance-variable instrument to simultaneously measure and compare the polymerization stress (PS) evolution, degree of conversion (DC), and exotherm of a bulk-fill flowable composite to a…
Highlights • Resin adhesives may be used as modeler liquids of resin composites. • Modeler liquids applied within increments of composite may improve its strength. • Hydrophobic resins are more…
Abstract Objective The effect of filler content in dental restorative composites on the polymerization shrinkage stress (PS) is not straightforward and has caused much debate in the literature. Our objective…
Abstract Objective To determine the nanohardness and elastic moduli of two bulk-fill resin based composites (RBCs) at increasing depths from the surface and increasing distances laterally from the center after…
Abstract Purpose to evaluate influence of cyclic fatigue on two resin infiltrated ceramics and three all-ceramic crowns manufactured using CAD/CAM technology. Materials and methods CAD/CAM anatomically shaped crowns were manufactured…
