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 ...
