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

Journal 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.

Effect of build orientation on the fabrication trueness of additively manufactured implant‐supported complete arch interim fixed prostheses

Journal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate how build orientation affects the fabrication trueness of additively manufactured implant‐supported complete arch prostheses by comparing them to subtractively manufactured high‐impact polymer‐based prostheses. Materials and Methods An edentulous maxillary model with four implants at canine and first molar regions ...

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

Journal 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 ...

The effects of material thicknesses and substrates on the translucency and color masking ability of additively manufactured definitive crown materials

Journal of Prosthodontics, EarlyView.
Abstract Purpose To investigate the translucency of the new 3D‐printable materials concerning thickness and the color masking ability of each material against different substrate colors. Materials and Methods Ninety square‐shaped specimens (12.0 mm × 12.0 mm) of two new 3D‐printable materials: ceramic‐infiltrated hybrid resin composite (VS) and light ...

Surface roughness, stainability, and translucency of an additively manufactured interim resin reinforced with a commercially available ceramic composite concentrate after coffee thermal cycling

Journal of Prosthodontics, EarlyView.
Abstract Purpose To compare the surface roughness (Ra), stainability, and translucency of a ceramic composite concentrate‐reinforced interim resin with its corresponding non‐reinforced formulation and with a ceramic‐filled resin indicated for definitive use after coffee thermal cycling.

An Escherichia coli Phosphotransferase System Modulates Methylglyoxal Resistance by Regulating Intracellular Potassium

Molecular Microbiology, EarlyView.
Escherichia coli can survive methylglyoxal stress by modulating phosphorylation of a regulatory phosphotransferase system, which, in turn, regulates the activity of a potassium/proton antiporter. The constitutive potassium importer Trk also contributes to intracellular potassium levels.
