Abstract Low temperature degradation of zirconia (3Y-TZP) oral implants and its effect on fatigue reliability is poorly documented. Objective The aim of this investigation was to follow the aging process…
Abstract Objective Conventional dental composites with randomly dispersed inorganic particles within a polymer matrix fail to recapitulate the aligned and anisotropic structure of the dentin and enamel. The aim of…
Abstract Objective To investigate the short- and long-term in vitro wear resistance of experimental resin-based composites (RBCs) derived from a commercial formulation. Methods Six experimental RBCs were manufactured by manipulating…
Abstract Objectives Phosphoric acid-Bioglass 45S5 paste can create an interaction layer formed of calcium-phosphate crystals on the dentin surface. In this study, the efficiency of decreasing the dentin permeability exerted…
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…
