Analysis of Mechanical Properties and Printing Orientation Influence of Composite Resin for 3D Printing Compared to Conventional Resin.

This study aimed to compare the flexural strength, surface roughness, and microhardness of a resin for three-dimensional (3D) printing and a conventional composite resin and to evaluate whether the printing orientation influences these properties. To evaluate the flexural resistance, test specimens were produced and divided into four groups: three groups of resins for 3D printing with inclinations of 0°, 45°, and 90° and one group of conventional composite resin. Forty discs were produced and subjected to a sandpaper-polishing sequence, and the surface roughness was measured using a roughness meter.

Laypersons' Esthetic Perception of Different Dentogingival Characteristics Based on Smile Dynamics: Cross-Sectional Study.

This study aimed to evaluate laypersons' esthetic perception of different dentogingival characteristics based on smile dynamics. Six voluntary models were selected, with only one presenting dentogingival characteristics within esthetic standards: white teeth, good alignment, and adequate gingival contour. Two videos were then produced.

Healthy living behaviors in youth: a comparative study in Brazil, Colombia and Mexico.

The physical, mental and social well being, refers to a new concept of health, far from a conceptualisations of absence of disease Additional challenges emerge as individuals face deep social inequities depending on their ethnicity, rural residence or low educational level, as these translate to poor access to health services and more difficulties to adhere to healthy living behaviors. The objective of this study was to assess the perception that adolescents and young adults in Latinamerica have of the importance of healthy living behaviors (HLB) in the physical, emotional and lifestyle spheres. The approach is considered quantitative and descriptive with a cross sectional design.

Results and effects of patients who have recovered from COVID-19: identifying the relationship with risk factors and comorbidities.

The number of deaths from COVID-19 is closely associated with multimorbidities. This study aimed to review the clinical and functional conditions of patients who recovered from COVID-19. Additionally, identify the relationship with risk factors and comorbidities.

Correlation between baropodometric variables, disability, and intensity of low back pain in pregnant women in the third trimester.

Background: Growth of uterus, enlargement of breasts and weight gain result from the development and growth of the fetus during pregnancy. The posture and the displacement of the center of gravity change.

Objective: Correlate baropodometric variables with low back pain in pregnant women in the third trimester of pregnancy.
