Novel bilayered zirconia systems using recycled 3Y-TZP for dental applications.

Objective: To synthesize bilayer zirconia systems based on commercial or recycled 3Y-TZP obtained from non-milled remnants and to compare their optical and mechanical properties before and after aging.

Methods: Bilayer zirconia samples were fabricated using either recycled 3Y-TZP (3Y-R/4Y and 3Y-R/5Y) or commercial powders (3Y/4Y and 3Y/5Y). Microstructure and phase composition were analyzed using ScanningElectronMicroscopy (SEM) and X-Ray Diffraction (XRD).

Effectiveness of a physiotherapist-led triage and treatment service on WAITing time for adults with musculoskeletal pain referred to Australian public hospital physiotherapy clinics: a protocol for the WAIT-less trial.

Introduction: Musculoskeletal pain is the second leading cause of disease burden in Australia, and there is a need to investigate new models of care to cope with the increasing demand for health services. This paper describes the protocol for a randomised controlled trial investigating whether a physiotherapist-led triage and treatment service is non-inferior for improving function at 6 months and superior for reducing treatment waiting times, compared with usual care for patients with musculoskeletal pain referred to public hospital outpatient physiotherapy clinics.

Methods And Analysis: A total of 368 participants (184 per arm) will be recruited from six public hospitals located in metropolitan Sydney, Australia.

Experimental bilayer zirconia systems after aging: Mechanical, optical, and microstructural characterization.

Objectives: To characterize two experimental zirconia bilayer materials compared to their monolithic controls, before and after hydrothermal aging.

Methods: Commercial zirconia powders were utilized to fabricate two bilayer materials: 3Y-TZP+ 5Y-PSZ (3Y+5Y/BI) and 4Y-PSZ+ 5Y-PSZ (4Y+5Y/BI), alongside control groups 3Y-TZP (3Y/C), 4Y-PSZ (4Y/C), and 5Y-PSZ (5Y/C). Compacted specimens were sintered (1550 °C- 2 h, 3 °C/min), and half of them underwent hydrothermal aging (134 °C-20h, 2.

Interrelation of Stress, Eating Behavior, and Body Adiposity in Women with Obesity: Do Emotions Matter?

Background/objectives: Obesity is influenced by biological, hormonal, and social factors, contributing to chronic diseases and burdening the healthcare system. Chronic stress and emotional eating are linked to weight gain, affecting eating behaviors and metabolism. This study aimed to assess the association between stress, eating behavior, and adiposity in obese women.

Fatigue behavior of sintered, glazed and glass-infiltrated surfaces of 5Y-PSZ bonded plates.

This study evaluated the effect of different occlusal surface finishes (glaze and silica glass infiltration) on surface characteristics and fatigue behavior of partially stabilized zirconia (PSZ) plates adhesively bonded onto epoxy resin discs. PSZ disc specimens (n = 15; Katana blocks STML, Kuraray Noritake Dental) were produced (Ø = 10 mm; thickness = 1.2 mm) and allocated into 3 groups: As sintered (S), silica glass infiltration (SGI), and glaze application (G).
