A comprehensive study on MDP effects: Microshear bond strength and fatigue resistance in 4YSZ ceramics.

The aim of this study is to assess the presence of MDP at various stages of the bonding procedure, enhance the adhesive and mechanical behavior of cemented zirconia ceramics. Fifty ceramic slices (15 × 15 × 2 mm) and 48 discs (Ø= 10 mm, 1 mm thickness) were prepared, sintered, air-abraded with aluminum oxide, and allocated considering: 1) microshear bond strength (µSBS) between ceramic slices and luting agent cylinders (height= 1 mm, Ø= 1.2 mm); 2) fatigue behavior, ceramic discs paired and bonded onto fiber-epoxy resin discs (Ø= 10 mm, 2.

Translation, Cross-Cultural Adaptation, and Validation of the Fear of Dependency Scale Into European Portuguese.

Background: Dependency is defined as a person's inability to meet basic human needs. In the context of aging, biopsychosocial changes compromise functionality, predisposing older adults to rely on others to perform daily activities. Fear of dependency describes the fear people have of appearing and/or being weak and/or reliant on others.

Evaluating mechanical and surface properties of zirconia-containing composites: 3D printing, subtractive, and layering techniques.

This study assessed the monotonic and fatigue flexural strength (FS), elastic modulus (E), and surface characteristics of a 3D printed zirconia-containing resin composite compared to subtractive and conventional layering methods. Specimens, including discs (n = 15; Ø = 15 mm × 1.2 mm) and bars (n = 15; 14 × 4 × 1.

3D printed, subtractive, and conventional acrylic resins: Evaluation of monotonic versus fatigue behavior and surface characteristics.

This study assessed the mechanical properties and surface characteristics of dental prosthetic acrylic resin fabricated by 3D printing, comparing it with subtractive, pressing, and molding techniques. Bar-shaped specimens (N= 90; 65 × 10 × 3.3 mm; ISO:207951) were prepared and assigned into six groups: PRINT (3D printing vis stereolithography with PriZma 3D Bio Denture, Makertech Labs); SUB (subtractive manufacturing with Vipiblock Trilux, Vipi); PRESS Base (pressing using muffle with Thermo Vipi Wave, Vipi for base); PRESS Tooth (pressing with Onda-cryl, Clássico for tooth); MOLD Base (molding using addition silicone with Vipi Flash, Vipi for base); and MOLD Tooth (molding with Dencor, Clássico for tooth).

Leg stiffness and muscle power vs manometer in sportswomen with symptoms of stress urinary incontinence.

Background: Pelvic floor muscle training can cure or alleviate stress urinary incontinence. This study aimed to evaluate maximum voluntary contractions of the pelvic floor muscle in sportswomen and verify the association with leg stiffness and muscle power, both maximal and submaximal.

Methods: The sample consisted of 41 sportswomen between 18 and 42 years of age.

Effects of pelvic floor muscle training in pregnant women.

Objective: The aim is to verify the effectiveness of the pelvic floor muscle training (PFMT) program in pregnant women, by analyzing the amount of urine leakage.

Design: Experimental study.

Location: Care units in the Vila Real district, Portugal.

Prevalence of Urinary Incontinence in High-Impact Sport Athletes: A Systematic Review and Meta-Analysis.

The aim of this study was to systematize the scientific evidence that assessed the prevalence of urinary incontinence in female athletes and determine which modality is most predisposed to stress urinary incontinence. From September to December 2018, a systematic literature search of current interventional studies of stress urinary incontinence of the last ten years was performed using PubMed, EMBASE, Scopus and Web of Science databases. The methodological quality was assessed by the Downs and Black scale, while the data collected from the studies were analyzed through meta-analysis.

Assessment of pelvic floor muscles in sportswomen: Quality of life and related factors.

Objectives: To evaluate Maximum Voluntary Contraction (MVC) of the Pelvic Floor Muscles (PFM) in sportswomen, to observe the urinary symptoms and their impact on the Quality of Life (QoL).

Design: Observational cross-sectional study.

Setting: Gyms and teams in the North of Portugal.

Pelvic Floor Muscle Training in Female Athletes: A Randomized Controlled Pilot Study.

The aim of this study was to investigate the effects of pelvic floor muscles training in elite female volleyball athletes and whether it is an effective therapy for stress urinary incontinence. Fourteen athletes, both continent and incontinent, between 18 and 30 years of age, were randomly assigned to an experimental group or a control group. The experimental group received a protocol for pelvic floor muscle training for 4 months.
