Abstract Objectives Mismatch in thermal expansion properties between veneering ceramic and metallic or high-strength ceramic cores can induce residual stresses and initiate cracks when combined with functional stresses. Knowledge of…
Abstract Objectives This study evaluated the risk of failure for an endodontically treated premolar with MOD preparation and three CEREC ceramic restoration configurations. Methods Simulations were performed based on three…
Abstract Objective In restored teeth, stresses at the tooth–restoration interface during masticatory processes may fracture the teeth or the restoration and cracks may grow and propagate. The aim was to…
Abstract Objectives To review the current status and understanding of Portland cement-like endodontic materials commonly referred to by the trade designation “MTA” (alias “Mineral Trioxide Aggregate”), and to present an…
Abstract Objective The aim of this paper is to validate the use of a finite-element (FE) based continuum damage mechanics (CDM) failure model to simulate the debonding and fracture of…
Abstract Objectives This study demonstrates the effects of nano-scale prepolymer particles as additives to model dental monomer and composite formulations. Methods Discrete nanogel particles were prepared by solution photopolymerization of…
Abstract Objective To investigate the contributions of BisGMA:TEGDMA and filler content on polymerization stress, along with the influence of variables associated with stress development, namely, degree of conversion, reaction rate,…
Abstract Objectives Piston-on-three-ball tests have been selected by the International Organization for Standardization to establish ISO 6872 for the evaluation of the biaxial strength of dentistry–ceramic materials. However, the formula…
Abstract Objectives The aim of this study was to evaluate the load-bearing capacity and microstrain of incisors restored with posts of various kinds. Both prefabricated titanium posts and different fiber-reinforced…
Abstract Objectives The aim of this study was to investigate the effects of HEMA and TEGDMA on the odontogenic differentiation potential of dental pulp stem/progenitor cells. Methods Dental stem/progenitor cell…
Abstract Objectives The purpose of this work was the detailed study of sorption characteristics of water or artificial saliva, the determination of flexural strength and the flexural modulus, and the…
Abstract Objectives To compare the bond strength of a ceramic veneer material to two different ceramic core materials using shear strength testing and finite element analysis (FEA). Methods 15 blocks…
Abstract Titanium implants are the gold standard in dentistry; however, problems such as gingival tarnishing and peri-implantitis have been reported. For zirconia to become a competitive alternative dental implant material,…
Abstract Objectives Less data are available about the effects of hydrogen peroxide on the three-dimensional polymer network of polymerized composites. Therefore the study was performed to test the effects of…
Abstract Objective To compare microtensile bond strengths (MTBS) subsequent to load cycling of resin bonded acid-etched or EDTA-treated dentin using a modified ethanol wet-bonding technique. Methods Flat dentin surfaces were…
Abstract Objectives To evaluate the micro-tensile bond strength (μTBS) and interfacial characteristics of adhesive–dentin bonds produced after caries-removal with contemporary techniques. Methods Carious molars were cut at the base of…
Abstract Objectives The aim was to investigate the influence of number average molecular weight and concentration of the poly(acrylic) acid (PAA) liquid constituent of a GI restorative on the compressive…
Abstract Objective To investigate the influence of curing mode and temperature on the shrinkage kinetics of self-adhesive resin cements in comparison to a conventional multi-step resin cement. Methods The shrinkage…
Abstract Objectives To evaluate the mechanical behavior of a prototype porous ceramic interpenetrating polymer–ceramic material containing 15–20% polymer. Methods After sample preparation, elastic modulus, hardness, stress–strain relationship and indentation creep…
