Microhardness of bulk-fill composite materials

, 2016
The aim of the study was to determine microhardness of high- and low-viscosity bulk-fill composite resins and compare it with conventional composite materials. Four materials of high-viscosity were tested, including three bulk-fills: QuiXfi l (QF), x-tra

Crash Behavior of DP800–DP1000 Advanced High‐Strength Steel’s Dissimilar Resistance Spot Welded Joints Under Quasi‐static and High Strain Rates

steel research international, EarlyView.
The high‐strain‐rate behavior of resistance spot‐welded DP800–DP1000 joints is investigated. Results show that microstructural gradients across BM–HAZ–FZ govern hardness, strain rate sensitivity, and failure modes. While strength increases with strain rate, energy absorption is controlled by ductility, with DP800–DP800 joints showing superior ...

Influence of Surface Roughness and Temperature on Niobium Cathodic Cage Duplex Treatment Applied to VP20TS Steel

steel research international, EarlyView.
Niobium cathodic cage duplex treatment is applied to VP20TS steel to evaluate the influence of surface roughness and temperature on coating performance. Results show that higher temperatures promote thicker nitride layers and increased microhardness, while finer surface preparation enhances adhesion and wear resistance, revealing optimal conditions for

Surface Micro‐Discharge Plasma for Multiple Teeth Bleaching: Efficacy, Mechanism and Safety

High Voltage, EarlyView.
ABSTRACT Hydrogen peroxide (H2O2) is the commonly‐used bleaching chemical in clinical practice, but its excessive concentrations can cause tooth damage. Atmospheric pressure cold plasma is considered a promising new technique for tooth bleaching. Surface micro‐discharge (SMD) devices can generate large‐scale plasma, which holds potential for treating ...

Surface Physical and Mechanical Properties of Short Fibre Reinforced Composite Resins in Direct Restorative Dentistry: A Systematic Review

Australian Dental Journal, EarlyView.
ABSTRACT Background Short Fibre Reinforced Composite resins may be used to restore odontogenic tissues and have enhanced physical and mechanical properties compared with conventional resins. However, their surface characteristics remain a concern, and this has limited their use as direct dental restorative materials.
