Abstract Objectives Zirconia based restorations exhibited high failure rates due to veneering–porcelain fractures. Milling to full-contour might be an alternative approach for zirconia restorations. The aim of this study was…
Abstract Objective To evaluate whether the reduction/prevention of triethylene glycol dimethacrylate (TEGDMA)-induced decrease of intracellular glutathione (GSH) protects human periodontal ligament fibroblasts (HPLF) against cell death. Methods HPLF were preincubated…
Abstract Objectives The aim of the study was to compare the strength of thin-walled molar crowns made of various materials under simulation of mastication. Methods Five 3D FE models of…
Abstract Objectives Esthetic restorations require that dental restorative materials have similar optical properties to teeth. To improve the color perception, the inhomogeneous morphology of the native tooth can be imitated…
Abstract Objective To explore experimental RBCs derived from a successful commercially available RBC (Grandio) to investigate resin monomer blend and filler parameters (volume fraction, density and diameter) on RBC performance….
Abstract Objectives In this study five novel dimethacrylates of different chain lengths having rigid aromatic rings were synthesized and proposed as possible dental monomers for dental resin mixtures. Methods Four…
Abstract Objectives Partially yttria stabilized zirconium oxide was introduced as core material for core-veneered full ceramic dental restorations, because of its biological inertness, high mechanical strength, and toughness. In order…
Abstract Objectives We had previously discovered that the flexural and tensile strengths of human dentin were 2–2.4 times greater after being heated to 140 °C, and deduced that the generation…
Abstract Objectives Since photoinitiator systems for dental resins based on camphorquinone (CQ) present color disadvantages, trimethylbenzoyl-diphenyl-phosphine oxide (TPO) has been proposed as an alternative. However, there are remaining considerations about…
Abstract Objectives Framework design is reported to influence chipping in zirconia-based restorations, which is an important cause of failure of such restorations. Residual stress profile in the veneering ceramic after…
Abstract Objective This work investigates the graft polymerization of acrylic acid onto nanoclay platelets to be utilized as reinforcing fillers in an experimental dental adhesive. Physical and mechanical properties of…
Abstract Objective To fabricate and characterize dental composites reinforced with various amounts of zirconia–silica (ZS) or zirconia–yttria–silica (ZYS) ceramic nanofibers. Methods Control composites (70 wt% glass particle filler, no nanofibers)…
Abstract Objectives The purpose of this study was to compare the mechanical and rheological properties of resin-based pit and fissure sealants to flowable resin composites in order to define clinical…
Abstract Tissue engineering is an interdisciplinary field that combines the principles of engineering, material and biological sciences toward the development of therapeutic strategies and biological substitutes that restore, maintain, replace…
Abstract Objectives Innumerous modifications have been proposed for the microtensile test since its introduction; however, testing parameters are not often well described and wide variations in bond strength are commonly…
Abstract Objective It had previously been shown that the inverse-square law does not apply to the force–distance relationship in the case of a long, thin magnet with one end in…
Abstract Objectives The purpose of this study was to ascertain whether the amount of Zn in gold alloys contributes to porcelain–metal bonding. Methods Experiments were carried out using a commercial…
Abstract Objective Tricalcium silicate is the major constituent phase in mineral trioxide aggregate (MTA). It is thus postulated that pure tricalcium silicate can replace the Portland cement component of MTA….
Abstract Objectives Previous studies have developed calcium phosphate and fluoride releasing composites. Other studies have incorporated chlorhexidine (CHX) particles into dental composites. However, CHX has not been incorporated in calcium…
Abstract Objectives The aim of the present study was to investigate the caries-preventive effect of sealants produced with a high-viscosity glass-ionomer with an elevated powder-liquid ratio (ART), of having energy…
