Differently from scientific journals that undergo a rigorous peer review process prior to publication, the same level of demand is not found on social media.

Treatment of Class II malocclusion with anterior open bite and posterior crossbite with the aid of mini-implants in a patient with Down syndrome: Clinical case report.

Objective: We report the orthodontic treatment of a class II malocclusion with anterior open bite and posterior crossbite in a patient with Down syndrome (DS) treated with mini-implants.

Results: The results obtained at the end of the treatment were satisfactory, with improvements in occlusion, including bite closure; maxillary expansion; and the correction of dental relationships.

Astrocyte Reaction to Catechol-Induced Cytotoxicity Relies on the Contact with Microglia Before Isolation.

Astrocytes preserve the brain microenvironment homeostasis in order to protect other brain cells, mainly neurons, against damages. Glial cells have specific functions that are important in the context of neuronal survival in different models of central nervous system (CNS) diseases. Microglia are among these cells, secreting several molecules that can modulate astrocyte functions.

Does dental trauma and its consequences influence the professional hiring process? Development, validation and application of an assessment tool.

Objectives: To develop and validate a questionnaire concerning the aspects evaluated during the hiring process by human resources professionals (HRPs); to apply the validated questionnaire; and to evaluate the perceptions and judgment of HRPs regarding different traumatic dental injuries (TDIs) and their consequences (TDI-Cs).
