Hardfacing metals are widely used in arc welding and plasma transfer arc technologies and industries. However, application of hardfacing in agriculture is limited due to low toughness after weld depos...
The purpose of this study is to verify the hypothesis that the hardness and flexural strength of composite resin restorative materials are correlated and similarly affected by accelerated aging. With ...
The formation of renal and urinary calculi is not due to a single cause but occurs as a multifactor entity, by which some of them still are unknown. Three theories of Stones formation including nuclea...
During the cementation of metallic restorations, the polymerization of dual-curing resin cements depends exclusively on chemical activation. This study evaluated the influence of chemical activation c...
The microhardness of a bleaching-shade resin composite polymerized with different light-curing units was evaluated. Composite samples (3M ESPE Filtek Supreme) were applied to brass rings (2 mm in thic...
This study evaluated the Knoop hardness of a dual-cured resin cement (Rely-X ARC) activated solely by chemical reaction (control group) or by chemical / physical mode, light-cured through a 1.5 mm thi...
The aim of this study was to evaluate the following acrylic resins: Cl醩sico?/sup>, QC-20?/sup> and Lucitone?/sup>, recommended specifically for thermal polymerization, and Acron MC?/sup> and VIPI-WAVE...
The purpose of this study was to evaluate the Shore A hardness and surface roughness of two silicones for maxillofacial prosthetic treatment, under the influence of chemical disinfection and storage. ...
The objective of this study was to evaluate the l exural strength () and hardness (H) of direct and indirect composites, testing the hy- f potheses that direct resin composites produce higher and ...
This study investigated the effects of disinfecting alginate impressions on the scratch depth of resultant stone models. Eleven brands of alginate impression material and two disinfectants, 1% sodium ...
This study investigated the Knoop hardness of a thin layer in three dual-cured resin cements (Linkmax HV, Nexus 2, and Variolink II HV) irradiated through or not through different thicknesses (1 throu...
CP Ti was mirror-polished and then abraded with waterproof SiC papers of two different grit sizes: 16 and 3μm. As-polished and abraded surfaces were characterized by means of EPMA, XPS, XRD, and hardn...
The purpose of this study was to evaluate the effects of four different ratios of silanized mica filler and milled glass fiber on the surface hardness of an acrylic denture tooth material. Acrylic res...
Biomechanical properties of bonded dentin are important for resin restorations. We hypothesized that there are no differences in the hardness and elasticity of sound and caries-affected primary dentin...
This study investigated the characteristics of output light from different types of light curing units, and their effects on polymerization of light-activated composite resin. Three quartz-tungsten-ha...
