Abstract Objectives Polymerization of composite restorations causes shrinkage, which deforms and thus stresses restored teeth. This shrinkage deformation, however, has been shown to decrease over time. The objective was to…
Abstract Objective To test the hypothesis that the difference in the coefficient of thermal contraction of the veneering porcelain above ( α liquid ) and below ( α solid )…
Abstract Objective Novel root-end filling materials are composed of tricalcium silicate (TCS) and radiopacifier as opposed to the traditional mineral trioxide aggregate (MTA) which is made up of clinker derived…
Abstract Objective The goal of this work is to investigate t–m phase transformation, and subsurface damage in 3Y-TZP after sandblasting. Methods Commercial grade 3Y-TZP powder was conventionally sintered and fully…
Abstract Objectives The aim of this study was to compare the effects of three different surface treatments in enhancing porcelain zirconia bonding. Methods Totally, 160 densely sintered zirconia specimens were…
Abstract Objective This study evaluated the effect of different chemical surface treatments on the adhesion of resin-core materials to methacrylate resin-based glass fiber posts. Methods Two types of glass fiber…
Abstract Objective Bacteria persisting in the root canal system may thwart endodontic therapy. It is therefore interesting to know whether clinically available root canal sealers have an antimicrobial effect. The…
Abstract Objectives The aim of this study was to use high-pressure high-temperature (HP/HT) polymerization to produce urethane dimethacrylate (UDMA)–triethylene glycol dimethacrylate (TEGDMA) based resin composite blocks (RCB) suitable for dental…
Abstract Objective A theoretical model, based on fluid dynamics, was developed to measure impression pressure. The purpose of this study was to evaluate the validity of this theoretical model by…
Abstract Objective Studies observing early wound healing periods around dental implants demonstrate an implants ability to enhance osseointegration, the bone–implant interactions for extended healing periods though have not been thoroughly…
Abstract Objectives Hydroxyapatite (HA), fluor-hydroxyapatite (FHA) with varying levels of fluoride ion substitution and fluorapatite (FA) production has been characterised and optimised by the sol–gel method and the dissolution and…
Abstract Objectives To describe the effect of fatigue on the strength of the bracket–adhesive–enamel complex and characterize the fatigue behavior of the materials tested. Methods Upper central incisor brackets (Discovery…
Abstract Objectives The aim of this study is evaluating the antibacterial activity of resin composites containing ZnO nanoparticles against Streptococcus mutans and examining their physical and mechanical properties. Methods The…
