Abstract Objectives The purpose of this study was to evaluate the relationship between changes in the modulus of elasticity and ultimate tensile strength of one-step self-etch adhesives, and their degree…
Abstract Objective To compare resin–dentin bond strengths and the micropermeability of hydrophobic vs. hydrophilic resins bonded to acid-etched or EDTA-treated dentin, using the ethanol wet-bonding technique. Methods Flat dentin surfaces…
Abstract Purpose To evaluate important material properties of six experimental resin-based restorative materials (EXP) with systematically modified resin matrices using conventional and alternative monomers in comparison with an experimental standard…
Abstract Objective Various chemical interactions can be used to develop ceramic–resin bonding and specific approaches are available for zirconia ceramics. This study evaluated the effect of a new experimental primer,…
Abstract Objectives To distinguish the physical properties of a new silorane-based restorative material in comparison to five methacrylate-based restorative materials – a compomer, giomer, nanocomposite, hybrid and micro-hybrid. Methods The…
Abstract Objectives Since stylus profilometry applies a force on the sample surface, it is logical to hypothesize that the profilometer penetrates the surface of the enamel softened by acid solutions….
Abstract Objectives This study evaluated the role of endogenous dentin MMPs in auto-degradation of collagen fibrils within adhesive-bonded interfaces. The null hypotheses tested were that adhesive blends or chlorhexidine digluconate…
Abstract Objectives (1) To evaluate the changes in surface roughness and gloss after simulated toothbrushing of 9 composite materials and 2 ceramic materials in relation to brushing time and load…
Abstract Objectives The aim of the study was to characterize the chemical composition, microstructure and roughness of two commercially available zirconia dental implants (WhiteSky and Zit-Z). Methods The chemical composition…
Abstract Objectives The aim of this study was to compare the curing reaction of five experimental adhesive blends containing different photo-initiating systems. The hypothesis tested was that degree of conversion…
Abstract Objective There is a great demand for dental implant surfaces to accelerate the process of peri-implant bone generation to reduce its healing time and enable early loading. To this…
Abstract Objectives The aim of the present work was to perform the first in vitro evaluation of a new interfacial bond-promoting material-and-method concept for on-demand long term bacteria inhibition in…
Abstract Objectives Evaluate the flexural strength ( σ ) and subcritical crack growth (SCG) under cyclic loading of glass-infiltrated alumina-based (IA, In-Ceram Alumina) and zirconia-reinforced (IZ, In-Ceram Zirconia) ceramics, testing…
Abstract Objectives This study evaluates the hypothesis that the incorporation of fibrous hydroxyapatite nanoparticles with high crystallinity and high aspect ratio, synthesized by hydrothermal method, into an experimental ethanol-based one-bottle…
Abstract Objectives The aim of this study was to measure the initial dynamic viscoelastic modulus change of dental composites during light curing using a custom made oscillation rheometer. Methods Six…
Abstract Objectives It has been the focus to develop low shrinkage dental composite resins in recent ten years. A major difficulty in developing low shrinkage dental materials is that their…
Abstract Objectives To reduce the effect of stresses due to volumetric shrinkage the authors propose an incremental technique for placing composite restorations. Methods The goal of the method is to…
Abstract Objectives The aim of this study was to develop a method for measuring the slumping tendency of flowable resin composites and to correlate the results with those obtained from…
Abstract Objective Measuring the structure, composition or suitability for bonding of the acid-etched dentin substrate, especially in its hydrated state, has been a formidable problem. The purpose of this study…
Abstract Objectives To evaluate and compare bond strengths of different primers and resin cements to silica-based and zirconia ceramics. Methods Silica-based and zirconia ceramic specimens were ground flat with #600-grit…
