Ultra‐High‐Speed Sintering of 3.5Y‐TZP Zirconia: Time Reduction Without Compromising Translucency

open access: yesJournal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objectives To assess, firstly, the impact of three sintering speeds on translucency and grain size of 3.5Y‐TZP zirconia (Katana HT) across clinically relevant thicknesses, and secondly, the effect of thermocycling on translucency. Materials and Methods Disc specimens were fabricated at six thicknesses (0.7–2.0 mm) and sintered using SLOW (7 h),

Development of portable microfading spectrometers for measurement of light sensitivity of materials

open access: yes, 2011
Microfading was originally designed for efficiently detecting extremely light-sensitive materials on objects in situ to determine the appropriate exhibition lighting conditions. By focusing an intense beam of light to a tiny submillimetre sized spot and

New Insights into Wine Color Analysis: A Comparison of Analytical Methods to Sensory Perception for Red and White Varietal Wines

open access: yes, 2023
The Glories method and CIE L*a*b* color space are poorly correlated in the light red high-saturation color area. Non-uniformities in the CIE L*a*b* color space have led to the CIEDE2000 formula, while the Euclidean color distance is still used in wine ...

Effects of Surface Abrasion With Airborne‐Particles and Surface Etching With Hydrofluoric Acid on Color Difference and Translucency of Nano‐Hybrid Ceramic

open access: yesJournal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objectives To evaluate the effects of alumina airborne‐particle abrasion, glass‐bead airborne‐particle abrasion, and hydrofluoric acid etching of intaglio surfaces on the color difference and translucency of a nano‐hybrid ceramic after cementation to resin abutment specimens, and to analyze the relationships between surface roughness and these

Effect of sintering cycle on the strength and translucency of multilayered zirconia

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose A newly introduced sintering protocol promises to offer higher translucency while not significantly compromising the flexural strength of the material. However, the effect of the novel sintering protocol has not been thoroughly validated.

Developing a Colorimetrically Balanced, Measurement-Based Petal Colour System for Cultivated Rose (Rosa L. Cultivars) and the Resulting Colour Categories

open access: yesPlants
There is no practical and at the same time objective colour system available for describing cultivated roses (Rosa L. cultivars). For this reason, a new colour classification system was developed which is colorimetrically balanced and appropriate for ...

Shade variability and stability in interim and definitive tooth‐colored resin‐based restorative materials: Comparing manufacturer‐claimed shades to a universal shade guide

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate the shade variability and stability of interim and definitive tooth‐colored restorative materials by comparing manufacturer‐claimed shades to a universal shade guide before and after thermocycling. Materials and Methods Eight commercially available tooth‐colored restorative materials were tested, including conventional ...

CONSTRUÇÃO DE ESPAÇOS DE COR EUCLIDIANOS E PERCEPTUALMENTE UNIFORMES COM BASE NA FÓRMULA CIEDE2000

open access: yes, 2012
Nos últimos anos, diversas fórmulas de diferença de cores foram desenvolvidas para o espaço CIELAB, tais como CMC, CIE94 e CIEDE2000. Embora essas fórmulas obtenham maior precisão na medida perceptual entre cores, muitas aplicações não podem usufruir ...

Görsel Renk Eşleştirmede CIE94 ve CIEDE2000 Renk Farkı Formüllerinin Karşılaştırılmas

open access: yes, 2023
Amaç: Son yıllarda renk eşleştirme çalışmalarında temel referans olarak kabul edilen E değerinin tespiti için kullanılan CIELab değerlerine dayalı formülasyon yerine insan gözünün renk algısını daha iyi yansıttığı düşünülen CIEDE2000 formülasyonunun kullanılması önerilmektedir.
