Effects of gastric acid on surface roughness, microhardness, fracture strength, and color change of dental ceramics: A systematic review of in vitro studies

Journal of Prosthodontics, EarlyView.
Abstract Purpose This systematic review evaluated the effects of simulated gastric acid (SGA) on surface and mechanical properties of dental ceramics to answer the research question: Does immersion in SGA alter the surface roughness, microhardness, fracture strength, and color of dental ceramics?

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

Journal 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

Journal 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 effect of toothpaste and thermal aging on extrinsically stained additively manufactured zirconia: A comparative study on surface roughness and stain durability

Journal of Prosthodontics, EarlyView.
Abstract Purpose The purpose of this in vitro study was to compare the average surface roughness (Ra) and stain durability of extrinsically stained additively manufactured zirconia, after brushing with different toothpastes and thermal cycling, with those of subtractively manufactured zirconia and lithium disilicate.

A systematic color correction pipeline for controlled‐environment imaging

The Plant Phenome Journal, Volume 9, Issue 1, December 2026.
ABSTRACT We present a stepwise color correction (CC) pipeline for controlled imaging environments. The workflow integrates flat‐field correction (FFC), gamma correction, and white‐balance correction, followed by a color‐mapping (CM) stage using machine‐learning regression—linear, partial least squares, and neural networks (NNs)—to deliver reliable CC ...
