Abstract Objectives The aim of this study was the detection of putative gene expression-related effects of dental composites in conventional and interactive gingival cell systems. Methods Conventional monoculture (MC) and…
Abstract Objectives Aim of the present study was to evaluate fracture strength of endodontically treated molars with different preparations/restorations after thermomechanical loading in vitro. Methods 264 extracted human third molars…
Highlights • Infiltrating the zirconia cementation surface with glass can substantially improve its resin bonding strength. • The interfacial fracture energy for glass-infiltrated graded zirconia is similar to that of…
Abstract Objective Hypersensitivity of non-carious cervical lesions (DH) is a frequently encountered disease. This randomized, controlled, single-blind crossover study evaluated the effectiveness of a calcium phosphate containing desensitizer paste (TAP)…
Highlights • Osteoinductive properties of Bioroot™ RCS was compared to Kerr’s Pulp Canal Sealer™ using the mouse pulp-derived stem cell line A4, which have an osteo/odontogenic potential in vitro ….
Abstract Objectives Cure, volumetric changes and mechanical properties were assessed for new dental composites containing chlorhexidine (CHX) and reactive calcium phosphate-containing (CaP) to reduce recurrent caries. Methods 20 wt.% of…
Abstract Objectives To detail the development of ester-free thiol–ene dental resins with enhanced mechanical performance, limited potential for water uptake/leachables/degradation and low polymerization shrinkage stress. Methods Thiol-terminated oligomers were prepared…
Highlights • A simple optical method for measuring free shrinkage is compared with a dilatometer. • Shrinkage values with optical method ranked the same but were higher than dilatometer. •…
Abstract Objectives To assess the performance of thiol–ene dental composites based on selected ester-free thiol–ene formulations. Further, to point out the benefits/drawback of having a hydrolytically stable thiol–ene matrix within…
Abstract Objective To investigate the effect of firing protocols on flexural strength, surface roughness, and crystalline structure of a leucite-based glass ceramic. Methods Discs produced by automated machining were distributed…
Highlights • Co–Cr alloys were produced from cast, CAD/CAM and powder metallurgy techniques. • Microstructure, crystal structure and chemical composition were analyzed. • Fcc phase stability was dramatically higher for…
Abstract Objective The aim of this study was to assess monomer elution from bulk-fill and conventional resin-composites stored in different media using high performance liquid chromatography (HPLC) for up to…
Abstract Objective To quantify the influence of fracture geometry and restorative materials rigidity on the stress intensity and distribution of restored fractured central maxillary incisors (CMI) with particular investigation of…
Highlights • A novel hybrid ceramic showed a higher loading capacity than feldspar ceramic cemented on one-piece zirconia implants. • The compressive strength of dental resin composite cements correlates with…
Highlights • Novel bioactive glass (BAG) and fluoride-containing BAG composites were prepared. • We investigated the effects of biofilm on the surface properties of these composites. • Both the biofilm…
Highlights • Physicochemical of experimental adhesive resins containing HEAA were determined. • HEAA increased degree of conversion and elastic modulus of experimental adhesives. • HEAA acted with co-initiator and increased…
Highlights • Self-etching Bondfill SB showed higher shear bond strength than EasyBond. • Operator’s experience level did not affect bond strength of Bondfill SB nor EasyBond. • Bondfill SB had…
Abstract Objectives To study the effect of resin matrix and maturation time (1 and 24 h) on the creep deformation of resin-composites, two of which have matrix-forming monomers that are…
Abstract Objective To evaluate degree of conversion (DC), Knoop microhardness (KHN), internal marginal adaptation (IA), and polymerization shrinkage stress (PS) of one conventional and four bulk-fill composites. Methods Bulk-fill composites…
