Biomodification of dentin collagen with hydroalcoholic propolis extract: Impact on resin–dentin adhesion

open access: yesEuropean Journal of Oral Sciences, EarlyView.
Abstract This in vitro study evaluated the effect of hydroalcoholic propolis extract (HPE) as a collagen cross‐linking agent for preserving the dentin–adhesive interface. Dentin beams from human third molars were demineralized with 10% phosphoric acid and assigned to five treatments: distilled water (control), 6.5% grape seed extract (GSE), and HPE at ...

Evaluation of Creep Life and Damage for AISI 304 Under Combined Tension/Torsion Multiaxial Loading

open access: yesFatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT In the present study, to investigate the effects of temperature and principal stress ratio on the multiaxial creep rupture time of AISI 304 stainless steel, creep tests were conducted under various principal stress ratios at 650°C and 700°C.

Influence of Finish Line and CAM Unit on the Marginal Adaptation and Margin Trueness of Lithium Disilicate Glass‐Ceramic and Composite Resin Onlay Restorations

open access: yesJournal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To evaluate the marginal adaptation and margin trueness of lithium disilicate glass‐ceramic (LDS) and glass‐filler reinforced composite resin (CR) onlays fabricated using three different finish lines and two chairside CAM units (4‐ and 5‐axis). Methods LDS (e.max CAD) and CR (Tetric CAD) onlays were fabricated on butt joint, chamfer,

Leveraging modified ex situ tomography data for segmentation of in situ synchrotron X‐ray computed tomography

open access: yesJournal of Microscopy, EarlyView.
Abstract In situ synchrotron X‐ray computed tomography enables dynamic material studies. However, automated segmentation remains challenging due to complex imaging artefacts – like ring and cupping effects – and limited training data. We present a methodology for deep learning‐based segmentation by transforming high‐quality ex situ laboratory data to ...

Trueness of the apical and middle root portion segments of 3D‐printed removable die and alveolar cast designs manufactured using stereolithographic 3D printing

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose The present study evaluated the effects of the root portion design, segment (middle vs. apical), and part (die vs. cast) on the trueness of three‐dimensional (3D)‐printed removable die‐cast complex. Material and Methods The trueness of apical and middle segments of the root portion of 45 3D‐printed removable dies and casts with three ...
