Abstract Objective To compare a shear bond strength test for resin composite cements developed in order to better consider the shrinkage stress (here termed “Swiss shear test”) with the shear…
Abstract Objectives To develop two experimental temporary crown and bridge materials with improved physicomechanical properties. Methods Commercial materials: Trim (TR, monomethacrylate, Bosworth) and Quicktemp2 (QT, dimethacrylate, Schottlander). Experimental materials: isobutyl…
Highlights • We evaluated the ability of a cross-linking agent (EDC) to improve the stability of demineralized dentin. • Demineralized dentin matrix underwent static or dynamic (chewing simulation) aging to…
Abstract Objectives The purpose of this study was to assess surface and subsurface damage on 4 CAD-CAM high-strength ceramics after grinding with diamond disks of 75 μm, 54 μm and…
Highlights • Color and translucency of model composites were affected primarily by the type of monomer. • Color stability was greatly affected by monomer and to a lesser extent by…
Abstract Resin bonding to dentin requires the use of self-etching primers or acid etching to decalcify the surface and expose a layer of collagen fibrils of the dentin matrix. Acid-etching…
Abstract Objectives To formulate and evaluate new dual cured resin composite based on the inclusion of eugenyl methacrylate monomer (EgMA) with Bis-GMA/TEGDMA resin systems for intracanal post cementation and core…
Graphical abstract Highlights • MAPO and CQ-based filled resin composites were mixed using four BisGMA/TegDMA ratios.. • Polymerization was monitored using both FT-NIRS and DEA and post-cure properties were also…
Abstract Objectives Bleaching treatments can affect release of components from conventional composites. In this continuing study the influence of two different bleaching gels on the elution of bulk-fill composite components…
The use of fiber posts, i.e. fiber-reinforced composite (FRC) root canal posts, has increased considerably since their introduction in the late 1980s. It is estimated that prefabricated solid fiber posts…
Highlights • There was significant difference in the response of human and other mammalian cell lines to dental composites making extrapolation of the results not accurate always. • The type…
Abstract Objectives To evaluate thin-film bond strength between a bonding agent and human dentin, using a scratch test, and the characteristics and accuracy of measurement. Methods One-step bonding agents (BeautiBond;…
Abstract Objectives Despite their various advantages, such as good esthetic properties, absence of mercury and adhesive bonding to teeth, modern dental composites still have some drawbacks, e.g., a relatively high…
Abstract Objectives This study evaluated the effect of etching using 2% proanthocynidin-containing 10% phosphoric acid 2% PA/10% PhA vs. 35% phosphoric acid 35% PhA on immediate (IM) and 6-months (6…
Highlights • No adequate CIELAB-based indices are available for whiteness evaluation in dentistry. • Visual data optimization methods allowed the development of a new whiteness index-WI D . • WI…
Graphical abstract Highlights • Mono or polycrystalline alumina particles were added to a dental porcelain. • Particle coating was carried out by heat treatment of a silica precursor. • The…
Highlights • Capacity of crown restorations to sustain high bite force has been measured on manufactured, anatomically-correct specimens for three classes of monolithic materials. • Extended finite element modeling has…
Highlights • Mechanical performance of air-abraded or acid-etched ceramic was investigated. • Abrasion and acid-etching reduced ceramic mechanical strength and reliability. • Abraded ceramic had the poorest mechanical performance among…
Abstract Objectives Bioactive glass forms a bone mineral apatite interface and can be engineered to promote optimal bone regeneration. Strontium (Sr 2+ ) stimulates osteoblast and inhibits osteoclast activities in…
Abstract Objectives This study evaluated the endogenous matrix metalloproteinase (MMP) activity of demineralized dentin matrix following 1 or 5 min pretreatment by various collagen crosslinkers. Generic MMP activity assay, total…
