Reference values for the Unsupported Upper Limb Exercise test in healthy adults in Brazil

J. bras. pneumol; 46 (1), 2020
ABSTRACT Objective: To establish reference values for the Unsupported Upper Limb EXercise (UULEX) test, which measures peak arm exercise capacity, in healthy adults in Brazil. Methods: This was a cross-sectional study, involving presumably healthy individuals ≥ 30 years of age who completed quest...

Reference values for spirometry in Brazilian children

J. bras. pneumol; 46 (3), 2020
ABSTRACT Objective: To generate reference values for spirometry in Brazilian children 3-12 years of age and to compare those values with the values employed in the equations currently in use in Brazil. Methods: This study involved healthy children, 3-12 years of age, recruited from 14 centers (primary ...

Validation of a new water-perfused high-resolution manometry system

ABCD (São Paulo, Impr.); 33 (4), 2020
ABSTRACT Background: High-resolution manometry is more costly but clinically superior to conventional manometry. Water-perfused systems may decrease costs, but it is unclear if they are as reliable as solid-state systems, and reference values are interchangeable. Aim: To validate normal values for a ...

Socioeconomic status and cardiovascular risk factors in young adults: a cross-sectional analysis of a Brazilian birth cohort

Rev. bras. epidemiol; 23 (), 2020
ABSTRACT: Introduction: In high-income countries, persons of high socioeconomic status (SES) have a lower cardiovascular risk. However, in middle and low-income countries, the results are controversial. Objective: To evaluate the association between family income and cardiovascular risk factors in yo...

Direct resin composite restoration of endodontically-treated permanent molars in adolescents: bite force and patient-specific finite element analysis

J. appl. oral sci; 28 (), 2020
Abstract Objective To evaluate the influence of three levels of dental structure loss on stress distribution and bite load in root canal-treated young molar teeth that were filled with bulk-fill resin composite, using finite element analysis (FEA) to predict clinical failure. Methodology Three first ...

Resin-dentin bond stability of etch-and-rinse adhesive systems with different concentrations of MMP inhibitor GM1489

J. appl. oral sci; 28 (), 2020
Abstract Enzymatic degradation of the hybrid layer can be accelerated by the activation of dentin metalloproteinases (MMP) during the bonding procedure. MMP inhibitors may be used to contain this process. Objective To evaluate the degree of conversion (DC%), dentin bond strength (µTBS) (immediate and ...

Class II malocclusion treatment changes with the Jones jig, Distal jet and First Class appliances

J. appl. oral sci; 28 (), 2020
Abstract Objective Maxillary molar distalization with intraoral distalizer appliances is a non-extraction orthodontic treatment used to correct molar relationship in patients with Class II malocclusion presenting maxillary dentoalveolar protrusion and minor skeletal discrepancies. This study compares th...

Correlation between the cephalometric measurements and acoustic properties of /s/ sound in Turkish

J. appl. oral sci; 28 (), 2020
Abstract Objectives To evaluate the acoustic properties of the /s/ sound in individuals with different occlusion types and to investigate relationships between these properties and cephalometric measurements. Methodology Sixty patients were divided into three groups based on malocclusion. Group 1 inclu...
