Characterization of Dental Composite Resin with Additional TiO2 Nanoparticle Filler

Macromolecular Symposia, EarlyView.
Silanized SiO2‐based dental composite resins with and without TiO2 nanoparticle addition were fabricated using a Bis‐GMA/TEGDMA resin matrix and photopolymerized under 468‐470 nm UV light. The resulting composites, composite I (55% SiO2) and composite II (50% SiO2 + 5% TiO2), were characterized via scanning electron microscopy (SEM), Fourier transform ...

Depiction Fidelity and Specificity in Direct MRI of Collagen: Addressing Signal Decay at the Microsecond Timescale

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Gap‐filled zero echo time (ZTE) acquisitions combined with dedicated short‐T2 hardware enable direct collagen imaging on the timescale of macromolecular (MM) signals, with T2s ˜ 10 μs. However, present methods offer limited depiction fidelity, and their specificity towards MM content is poorly understood. This work presents methodology

Molar incisor hypomineralisation: current knowledge and practice

International Dental Journal, EarlyView., 2020
Background Molar incisor hypomineralisation (MIH) is a common developmental dental condition that presents in childhood. Areas of poorly formed enamel affect one or more first permanent molars and can cause opacities on the anterior teeth. MIH presents a variety of challenges for the dental team as well as functional and social impacts for affected ...

Resin cements: Composite luting cements

, 2004
Resin cements (composite luting cements) are used for cementation all ceramic crowns in contemporary dental practice. These materials which are characterized by type of fillers, initiation system, their viscosity, mechanical properties (wear resistance, elastic modulus, compressive strength, tensile and shear strength), and by their physical properties

A comparative study of solubility between resin cement and self-adhesive resin cement

International Arab Journal of Dentistry, 2013
Resin cements have been largely used for luting indirect restorations due to their bonding abilities to the tooth structures and the increase of the restorations stability; however their solubility can negatively affect the restoration durability. The aim of this in vitro study was to evaluate and to compare water solubility values of conventional ...

Development of Biodegradable Talc‐Filled PBAT/PLA and PBSA/PBAT Binary Blend Films: Effects of Multilayer Architecture and Uniaxial Orientation on Performance

Polymer Engineering &Science, EarlyView.
PBAT‐based PLA and PBSA blend films were developed in single‐ and tri‐layer structures with talc and processed via blown film extrusion followed by uniaxial stretching. Multilayer design and MDO significantly enhanced mechanical strength, stiffness, barrier, and UV resistance through chain orientation and strain‐induced crystallization.

Cement selection for fixing implant restorations [PDF]

Stomatološki glasnik Srbije, 2019
Introduction When intraocclusal space is long enough, and patient has high aesthetic demands, cementing implant restoration is the proper choice. The aim of this study was to assess retentive forces of different cements used for fixing restoration to ...

Resin Content in Cement Liquids of Resin-Modified Glass Ionomers.

Dental Materials Journal, 1999
Qualitative and quantitative analyses were conducted on four kinds of resin-modified glass ionomer (RMGI) cement liquids, LC, LC II, LC III (hereinafter referred to as LCs) and VM, using HPLC and laser Raman spectroscopic methods. HPLC revealed that among the RMGI liquids LCs contain 31-32% HEMA (2-Hydroxyethyl methacrylate), and VM contains 18% of the

Circular Economy Pathways for End‐of‐Life Wind Turbine Blades and Their Environmental Implications and Potential Urban Applications

Sustainable Development, EarlyView.
ABSTRACT The rapid expansion of renewable energy, particularly wind power, is expected to generate large volumes of composite waste from end‐of‐life (EoL) turbine blades in the coming decades. Managing this material represents a significant environmental and logistical challenge worldwide.
