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 ...

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.

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

Post-cementation sensitivity of bridges cemented with different adhesive resin cements

Journal of Clinical and Experimental Dentistry
Post-cementation sensitivity remains a common clinical concern in fixed partial dentures (FPDs), with variations in adhesive resin cement formulations influencing patient discomfort and long-term success. This study aimed to compare post-cementation sensitivity in FPDs cemented with three different resin cements: self-adhesive resin cements, resin ...

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 ...

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.

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

The effects of desensitizing resin, resin sealing, and provisional cement on the bond strength of dentin luted with self-adhesive and conventional resincements [PDF]

, 2012
STATEMENT OF PROBLEM: Self-adhesive resin cements were designed to bond without any pretreatment of dentin. However, pretreatments such as the application of desensitizing resin or the resin sealing of dentin with priming/bonding solutions might ...
