Abstract Objectives To determine the post-cure depth of cure of bulk fill resin composites through using Vickers hardness profiles (VHN). Methods Five bulk fill composite materials were examined: Tetric EvoCeram…
Abstract Objectives Oral bacteria have evolved to form biofilms on hard tooth surfaces and dental materials. The antibiofilm effect of materials used for the restoration of oral function affects oral…
Abstract Objectives The objective of the present work was to study the curvature of very thinly, veneered Y-TZP discs of different framework thicknesses submitted to different firing times. Methods Fifteen…
Abstract Objectives To determine, by means of static fracture testing the effect of the tooth preparation design and the elastic modulus of the cement on the structural integrity of the…
Abstract Objectives Camphorquinone (CQ) is a widely used photoinitiator in dental visible light (VL)-cured resinous materials. However, little is known about the toxicity of CQ in human cells. This study…
Abstract Objectives To evaluate the effect of EDC on elastic modulus (E), MMPs activity, hydroxyproline (HYP) release and thermal denaturation temperature of demineralized dentin collagen. Methods Dentin beams were obtained…
Abstract Objectives The objective of this study was to demonstrate a successful binding of Doxy hyclate onto a titanium zirconium alloy surface. Methods The coating was done on titanium zirconium…
Abstract Objectives To analyse the influence of irradiation time, aging before bleaching, and bleaching technique (home bleaching vs. in-office bleaching) on the amount of elutable substances from modern nano-hybrid resin-based…
Abstract Objectives Antibacterial primer and adhesive are promising to inhibit biofilms and caries. Since restorations in vivo are exposed to saliva, one concern is the attenuation of antibacterial activity due…
Abstract Objectives The objectives of this study were to develop a chitosan bilayer membrane containing microspheres with sustained TGF-β 1 release to enhance odontoblast-like cell function in vitro, and to…
Abstract Objective This in vitro study was designed to investigate the influence of the veneer and cyclic loading on the failure behavior of lithium disilicate glass-ceramic (LDG) crowns on maxillary…
Abstract Objectives To synthesize and characterize different molar weight urethane multimethacrylates with a single stage (one-pot) procedure. To prepare and characterize the properties of related composites. Methods Two methacrylate precursors…
Abstract Objective To evaluate the extent and rate of hygroscopic expansion of resin composites at 37 °C. Methods Eight resin composites were examined: 1 micro-hybrid (Bright Light ® ), 5…
Abstract Objective The aim of this study was to develop a novel dental implant abutment with a micro-motion mechanism that imitates the biomechanical behavior of the periodontal ligament, with the…
Abstract Objectives In this work long term stability of a zirconia toughened alumina (ZTA) composite was investigated. Methods Accelerated aging tests under hydrothermal environment, in autoclave and hot water, at…
Abstract Objectives This in vitro study should assess the fracture resistance of veneered zirconia-based crowns with either luted or fused veneer. Methods Thirty-two identical zirconia frameworks (IPS e.max ZirCAD; Ivoclar/Vivadent),…
Abstract Fluorapatite glass-ceramics have been shown to be excellent candidates as scaffold materials for bone grafts, however, scaffold production by sintering is hindered by concurrent crystallization of the glass. Objective,…
Abstract Objectives The residual stress profile developed within the veneering ceramic during the manufacturing process is an important predicting factor in chipping failures, which constitute a well-known problem with yttria-tetragonal-zirconia…
