Abstract Objectives To verify the influence of filler size distributions on fracture toughness ( K Ic ), initial fracture strength (IFS) and cyclic fatigue resistance (CFR) of experimental resin composites….
Abstract Objectives To examine the effects of the combined use of chlorhexidine and ethanol on the durability of resin-dentin bonds. Methods Forty-eight flat dentin surfaces were etched (32% phosphoric acid),…
Abstract Objectives The aim of this study was to compare the viscoelastic properties of high pressure (HP) polymerized urethane dimethacrylate (UDMA) with those of control, ambient pressure thermo-polymerized and photo-polymerized,…
Abstract Objective Dental implants anchor in bone through a tight fit and osseo-integratable properties of the implant surfaces, while a protective soft tissue seal around the implants neck is needed…
Abstract Objectives Investigation of the hydration and characterization of Theracal and Biodentine used for pulp capping. Methods The setting mechanism and characterization of set Biodentine and Theracal after immersion in…
Abstract Objective The aim of this study is to explain the influence of peripheral interface stress singularities on the testing of tensile bond strength. The relationships between these theoretically predicted…
Abstract Objective The compliance for tooth cavity preparations is not yet fully described in the literature. Thus, the objectives were to present a finite element (FE) method for calculating compliance…
Abstract Objectives To evaluate the effect of different surface treatments on the bond strength between polyetheretherketone (PEEK) composite materials and each of two different luting cements. Methods One hundred specimens…
Abstract Objective To evaluate in vitro Streptococcus mutans ( S. mutans ) biofilm formation on the surface of five light-curing experimental dental bonding systems (DBS) with increasing hydrophilicity. The null…
Abstract Objective In this study, new dimethacrylate monomer SiMA without Bisphenol A (BPA) structure was synthesized and used as base resin of dental composite materials with the aim of reducing…
Abstract Objective This study investigates monitored micro-crack growth and damage in the ceramic/enamel adhesive interface using the acoustic emission (AE) technique with optical coherence tomography (OCT) under fatigue shear testing….
Abstract Objectives To report analytic solutions capable of identifying failure stresses from the biaxial flexure testing of geometries representative of endodontic access cavities prepared through dental restorative materials. Methods The…
Abstract Objective Recurrent caries at the margins is a primary reason for restoration failure. The objectives of this study were to develop bonding agent with the double benefits of antibacterial…
Abstract Objective The objective of this study was to test the following hypotheses: (1) both cyclic degradation and stress-corrosion mechanisms result in subcritical crack growth (SCG) in a fluorapatite glass-ceramic…
Abstract Objective The aim of this study was to evaluate the influence of in vitro pulpal pressure and cavity type on the tooth–composite bonding interface by means of acoustic emission…
Abstract Objectives To investigate chemo-mechanical effects of incorporating alkaline bioactive glass nanoparticles into a light-curable dental resin matrix. Methods An unfilled Bis-GMA/TEGDMA material was infiltrated with up to 20 wt%…
Abstract Objectives To identify the TiO 2 phases of the root surface of commercially available titanium dental implants, subjected to various surface treatments. Methods The titanium implants studied were: Allfit…
Abstract Objectives The ester linkages contained within dental resin monomers (such as Bisphenol A-glycidylmethacrylate (BisGMA) and triethylene glycol dimethacrylate (TEGDMA)) are susceptible to hydrolytic degradation by salivary esterases, however very…
Abstract Objectives Interaction between osteogenesis and angiogenesis plays an important role in implant osseointegration. In the present study we investigated the influence of titanium surface properties on the angiogenic behaviors…
Abstract Objective The aim of this prospective randomized-controlled clinical trial is to assess the long-term performance of two direct composite resins in posterior teeth. This study provides a survey of…
