The effects of material thicknesses and substrates on the translucency and color masking ability of additively manufactured definitive crown materials

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose To investigate the translucency of the new 3D‐printable materials concerning thickness and the color masking ability of each material against different substrate colors. Materials and Methods Ninety square‐shaped specimens (12.0 mm × 12.0 mm) of two new 3D‐printable materials: ceramic‐infiltrated hybrid resin composite (VS) and light ...

Effect of denture cleansers and surface treatments on the color stability, gloss, and wettability of CAD‐CAM denture bases

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate the impact of surface treatments and chemical denture cleansers on the surface color stability, gloss, and wettability of compression‐molded, 3D‐printed, and milled denture base materials. Materials and Methods Specimens (12 × 16 × 7 mm) were fabricated from a standardized STL file in three denture base materials ...

The Ecology of Human Sleep (EcoSleep) Cohort Study: Protocol for a longitudinal repeated measurement burst design study to assess the relationship between sleep determinants and outcomes under real‐world conditions across time of year

open access: yesJournal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary The interplay of daily life factors, including mood, physical activity, or light exposure, influences sleep architecture and quality. Laboratory‐based studies often isolate these determinants to establish causality, thereby sacrificing ecological validity.

Search for impact ejecta at the Paleocene–Eocene boundary

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Almost 10 years have passed since microtektites and microkrystites were reported for the Paleocene–Eocene (P–E) boundary in drill cores and outcrop in New Jersey and in ODP Hole 1051B in the western North Atlantic. The glassy spherules were interpreted to reflect an impact trigger for the Paleocene–Eocene Thermal Maximum (PETM).

Comparative Analysis of the Mechanical, Surface, and Dimensional Properties of 3D‐Printed Aligners: Influence of Printer Type and Nitrogen‐Assisted Post‐Curing

open access: yesOrthodontics &Craniofacial Research, EarlyView.
ABSTRACT Objectives This study aimed to compare the mechanical, surface, and dimensional properties of 3D‐printed clear aligners (CA) fabricated using liquid crystal display (LCD) and digital light processing (DLP) 3D printing systems with nitrogen treatment. Materials and Methods Specimens were manufactured using LCD (Uniz NBEE) and DLP (Nextdent 5100)

Evaluation of HSYA and Carthamin Accumulation in Safflower (Carthamus tinctorius L.) Induced by Chemical Mutagens (EMS and SA) in M1 and M2 Generations

open access: yesPlant Breeding, EarlyView.
ABSTRACT Historically cultivated for medicinal and dyeing purposes, safflower (Carthamus tinctorius L.) saw a shift towards widespread oilseed production after the 1920s due to the growing importance of oils. However, there is a renewed interest in its medicinal and dyeing properties today.
