Evaluation of physical, chemical, and color‐matching properties of monochromatic resin composites: An in vitro study

European Journal of Oral Sciences, Volume 134, Issue 4, August 2026.
Abstract The objectives of this study are to evaluate, in vitro, the microhardness, sorption, solubility, color stability, and color‐matching ability of monochromatic resin composites: Palfique Omnichroma / Tokuyama (Mono1) and Vittra APS Unique / FGM (Mono2) compared with the conventional resin composite: Filtek Z250 XT / Solventum (Conv).

Influence of printing orientation and post‐curing on optical and surface properties of definitive three‐dimensional‐printed dental resin with inorganic fillers

European Journal of Oral Sciences, Volume 134, Issue 4, August 2026.
Abstract This study evaluated the influence of printing orientation and post‐curing on the color stability, gloss retention, and surface microhardness of a definitive three‐dimensional (3D)‐printed dental resin, a high‐strength photopolymer with inorganic fillers designed for permanent restorations, after immersion in a staining solution.

In situ evaluation of the bleaching efficacy of experimental hydrogen peroxide hydrogel with MnO‐doped Biosilicate activated by violet LED light

European Journal of Oral Sciences, Volume 134, Issue 4, August 2026.
Abstract Hydrogen peroxide (HP) at 35% is effective for dental bleaching but may reduce enamel mineral content and induce structural changes. This study developed a bleaching‐hydrogel containing 6%HP and manganese‐oxide–doped Biosilicate (MnO_BioS), activated by violet LED, under in situ conditions.

Effect of in‐office bleaching on the color stability of bulk‐fill resin composites immersed in staining beverages

European Journal of Oral Sciences, Volume 134, Issue 4, August 2026.
Abstract This study evaluated the impact of in‐office bleaching on color stability of bulk‐fill composites submitted to staining. Bulk‐fill (Aura, Opus, and Filtek One) and nanofilled (Filtek Z350) composite specimens were submitted to the following: control (CT); bleaching and immersion in distilled water (BL); and bleaching with daily 15‐min ...

Toughening of TiO2 via Femtosecond Laser Shock Peening

Journal of the American Ceramic Society, Volume 109, Issue 8, August 2026.
ABSTRACT Most ceramics have low fracture toughness (<5 MPa m$\sqrt{m}$) at room temperature. This work explores the feasibility of toughening TiO2 via femtosecond laser shock peening (fs‐LSP). Transmission electron microscopy (TEM) analyses reveal LSP‐induced the creation of high‐density stacking faults, dislocation structures, and twin boundaries in ...

Enhancing Strength and Electrical Conductivity in Al–Zr–Sc Conductor Alloys Through Sn and Sr Microalloying and Two‐Step Aging Treatment

Advanced Engineering Materials, Volume 28, Issue 14, 22 July 2026.
Trace additions of Sn and Sr combined with a two‐step aging treatment are shown to enhance the microstructure and performance of Al–Zr–Sc conductor alloys. Strength and electrical conductivity increase concurrently through accelerated precipitation of fine Al3(Sc, Zr) precipitates and improved dislocation resistance, offering a cost‐effective pathway ...
