Seismic evaluation of the southbound Stellenberg Interchange Bridge, B5593, in South Africa

open access: yesStructural Concrete, EarlyView.
Abstract This study presents a nonlinear finite element assessment of the seismic vulnerability of Bridge B5593, located in the south‐western region of South Africa. Previous evaluations identified a high likelihood of column failure; however, these were based on linear material models incapable of capturing damage evolution.

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

open access: yesEuropean 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).

Cutaneous T‐cell lymphomas and dupilumab for atopic dermatitis: A systematic review and expert consensus

open access: yesJournal of the European Academy of Dermatology and Venereology, EarlyView.
Systematic review (51 studies; 547 patients) indicates dupilumab may unmask/worsen CTCL (mainly MF/SS). A French Delphi consensus recommends rigorous diagnostic workup, avoiding dupilumab in confirmed CTCL, discontinuing upon diagnosis, and favouring methotrexate or phototherapy.

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

open access: yesJournal 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

Transmission electron microscopy characterisation of Spirulina bioplastics

open access: yesJournal of Microscopy, EarlyView.
Abstract Plastic pollution is impacting global ecosystem health. Bioplastics made from unprocessed biomass, including whole or fragmented tissues, are one potential solution. They are biodegradable and exhibit competitive mechanical performance. Seaweed and microalgae have gained popularity over the last decade as bioplastic feedstocks due to their ...

Influence of nanohydroxyapatite mouthwash on the growth of Candida albicans biofilm on milled denture surfaces: An in vitro study

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose There is a need for effective solutions for the persistent prevalence of denture stomatitis (DS) in denture‐wearing populations. This study assessed the impact of nanohydroxyapatite (nanoHAP) nanoparticles on Candida albicans biofilm formation on milled polymethylmethacrylate (PMMA) denture bases.

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

open access: yesJournal 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?

Effects of printing temperature and post‐curing duration on the dimensional reproducibility and fracture load of 3D‐printed dental prostheses: An exploratory study

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose This in vitro study aimed to evaluate the effects of printing temperature and post‐curing duration on the dimensional reproducibility and mechanical properties of three‐dimensional (3D)–printed dental prostheses. Materials and Methods Photopolymer specimens were fabricated using a stereolithographic 3D printer at two temperatures: room
