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, EarlyView.
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.

A Study on DNN-Based Practical Model for Predicting Spot Color

Applied Sciences, 2023
The color of product packaging plays an important role in brand awareness and consistency. Given the importance of consistent color reproduction, the use of standardized spot colors is essential.

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, EarlyView.
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.

Post‐curing effects on mechanical properties staining resistance of a 3D‐printed resin versus a direct composite for definitive restorations

European Journal of Oral Sciences, EarlyView.
Abstract This study evaluated the mechanical performance and staining resistance of a three‐dimensional (3D)‐printed resin (VarseoSmile Crown Plus) subjected to different post‐curing times (0, 5, 10, 15, and 20 min), compared with a conventional nanofilled resin composite (Filtek Z350XT).

Perceptual Analysis of Tone Mapping Operators

JISR on Computing
Tone mapping is a crucial step in rendering, as it maps the High Dynamic Range (HDR) images to a Lower Dynamic Range (LDR) for display on standard devices. In this research, we address the challenge of selecting the most appropriate Tone Mapping Operator

Effect of in‐office bleaching on the color stability of bulk‐fill resin composites immersed in staining beverages

European Journal of Oral Sciences, EarlyView.
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 ...

The influence of post‐curing protocols on the optical properties of provisional and long‐term 3D‐printable resin composites

European Journal of Oral Sciences, EarlyView.
Abstract This study determined the influence of post‐curing protocols on the color stability of provisional and long‐term 3D‐printable resin composites. Disc‐shaped specimens were fabricated from a provisional (Prov) and long‐term (Crown) 3D‐printable resin composites using a digital light processing printer.

Effects of Substructure Color and Restoration Thickness on the Final Color of Ultra‐Translucent Zirconia Ceramics

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective This in vitro study aimed to evaluate the effects of substructure color and restoration thickness on the final color of shade‐gradient ultra‐translucent zirconia ceramics. Material and Methods A total of 180 flat‐shaped ultra‐translucent zirconia specimens (5Y‐PSZ) with thicknesses of 0.4, 0.6, and 0.8 mm (n = 60) were fabricated and
