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

European Journal of Oral Sciences, EarlyView.
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).

Color image quality metric s-cielab and its application on halftone texture visibility

, 1997
We describe experimental tests of a spatial extension to the CIELAB color metric for measuring color reproduction errors of digital images. The standard CIELAB E metric is suitable for use on large uniform color targets, but not on images, because color ...

Mechanisms underlying the protective effects of San‐Bai decoction against UV radiation on the skin

International Journal of Cosmetic Science, EarlyView.
Combining conventional differential expression analysis with differential network analysis offers a promising strategy to uncover the mechanistic basis of the holistic benefits provided by herbal blends. Our findings demonstrated that San‐Bai decoction modulates multiple pathways—not only those related to skin pigmentation, such as ET‐1 signalling, but

The influence of parametric effects on the appearance of small colour differences [PDF]

, 1997
The effects of the two physical parameters, background and gap, on the perception of small colour differences (AE* < 5) were investigated by use of 248 colour-difference pairs around 21 colour centres made from painted samples.

Effects of repeated exposure to ozonated water on hair fibre structure and integrity: Part I

International Journal of Cosmetic Science, EarlyView.
Repeated exposure to ozonated water caused cumulative oxidative changes in hair, altering structural integrity, thermal behaviour and mechanical properties. The findings reveal a distinct ozone‐induced damage profile that progresses beyond the cuticle, challenging claims of hair‐revitalizing benefits. Abstract Objective Ozone has recently been marketed
