Abstract Objective To compare long-term microtensile bond strength of zirconia, surface-modified via a novel treatment, to current surface conditioning methods for zirconia, when resin bonded to dental composite. Methods Two…
Abstract Objectives The aim of this study was to evaluate the effect of fatigue on biaxial flexural strength of bilayered disks of two Y-TZP cores. Methods Twenty bilayered veneer/zirconia disks…
Abstract Objective To determine streptococcal adhesion forces with composite resins with different surface roughness. Methods Polishing and grinding were applied to obtain smooth (roughness 20 nm), moderately rough (150 nm)…
Abstract Objectives The main challenges facing composite restorations are secondary caries and bulk fracture. The objectives of this study were to synthesize novel nanoparticles of amorphous calcium phosphate (NACP), develop…
Abstract Objective In this study acetyloxypropylene dimethacrylate was synthesized and proposed as an alternative monomer for triethyleneglycol dimethacrylate (TEGDMA) in dental mixtures. Methods The monomer was prepared by the reaction…
Abstract Objectives The aim of this study was to investigate the mechanical properties of denture base resin cross-linked with methacrylated dendrimer. Methods The test specimens (3 mm × 10 mm…
Abstract Objectives Resin-based dental materials are not inert in the oral environment, and may release components, initially due to incomplete polymerization, and later due to degradation. Since there are concerns…
Abstract Objectives The objective of this work was to develop a methodology for the prediction of fatigue life of the dentin–adhesive (d–a) interface. Methods At the micro-scale, the d–a interface…
Abstract Objective This paper studied in vitro the effect of the C -factor on interfacial debonding during curing of composite restorations using the acoustic emission (AE) technique. Finite element (FE)…
Abstract Objective To evaluate in vitro the pre-cementation resistance of CAD/CAM onlays subjected to functional occlusal tapping. Methods An extracted tooth model (molar and premolar) with simulated bone and periodontal…
Abstract Objectives To determine the effect of porcelain thickness and the application of a surface liner (SL) on the flexural strength ( σ ) of a ceramic system. Methods One…
Abstract Objectives While screening the activity of potential inhibitors of matrix metalloproteinases (MMPs), due to the limited water solubility of some of the compounds, they had to be solubilized in…
Abstract Objectives Regardless of the cause, gap formation at the tooth–restoration interface may result in treatment failure; non-destructive assessment and monitoring of these defects are important. The aim of this…
Abstract Objectives The manufacture of dental crowns and bridges generates residual stresses within the veneering ceramic and framework during the cooling process. Residual stress is an important factor that control…
Abstract Objective This investigation was to generate (1) guidelines for designing a tensometer that satisfies the necessary accuracy and sensitivity requirements for measuring polymerization stress (PS), and (2) a formula…
Abstract Objectives To assess the influence of different temporary restorations and luting techniques of labside and chairside ceramic inlays on enamel defects and marginal integrity. Methods 120 extracted human third…
Abstract Objective Investigation of the replacement of bismuth oxide by zirconium oxide in mineral trioxide aggregate (MTA) and characterization and evaluation of the radiopacity and physical properties of varying replacements…
Abstract Objectives Microleakage testing of dental materials is a commonly accepted evaluation technique of margin integrity. Thermocycling has been utilized by many researchers to study the influence of temperature extremes…
Abstract Objective Many dental materials are used in contact with each other in sandwich techniques. Liners, bases and permanent restorative materials are placed adjacent to each other and allowed to…
