Perceptions of research integrity and open science practices: a survey of Brazilian dental researchers.

The objective of this study was to evaluate Brazilian dental researchers' perceptions of research integrity and open science practices, as well as their perceptions of the way researchers are evaluated for promotion, hiring, and receiving grants. In a self-administered online survey, the respondents were presented with 3 questions on researcher evaluation in Brazil. Additionally, for 25 academic activities or characteristics, researchers rated their perceived importance for a) career advancement, b) science advancement, c) personal satisfaction, and d) social impact.

Persistent gender disparity in leading dental publications across 4 decades: an observational study.

Objectives: This observational study assessed the differences in the gender of the first and last authors in the most-cited dental articles over the last 4 decades.

Study Design And Setting: Articles were obtained through an electronic search of the most-cited articles in dentistry by decade (total n = 400 articles). The 100 most-cited studies in each decade (1980-1989, 1990-1999, 2000-2009, and 2010-2019), with any study design, with results in dentistry were eligible.

The impact of gender on citation rates: An observational study on the most cited dental articles.

Objective: This cross-sectional study aims to determine whether the gender of the authors plays a role in the position of authorship within the 100 most cited articles in dentistry.

Methods: An electronic search was performed in October 2022 in the SCOPUS database, considering filters by 'subject area' [dentistry], 'document type' [article], and 'source type' [journal]. The search was performed without restriction on the study design, publication yearor language.

Impact of COVID-19 on gender gap in dental publications: a retrospective cohort with three Brazilian journals.

This was a retrospective cohort study to investigate the impact of COVID-19 pandemic on the gender gap in articles submitted to three international dental journals based in Brazil. All submissions performed to Brazilian Dental Journal, Brazilian Oral Research, and Journal of Applied Oral Science before (2019) and during the pandemic (2020) were assessed. Gender of the first, last, and corresponding authors were collected.

Vitamin D Supplementation for Benign Paroxysmal Positional Vertigo: A Systematic Review.

Objective: Benign paroxysmal positional vertigo (BPPV) is commonly attributed to displaced otoconia. These have been shown to have biomineralization close to that of bone, and vitamin D deficiency has been associated with BPPV. We aim to systematically review the available literature on vitamin D supplementation and BPPV intensity and recurrence in adults.

Open science failed to penetrate academic hiring practices: a cross-sectional study.

Background And Objective: To evaluate the current hiring practices of academic institutions around the world, with regard to the mention of advertisements for Open Science (OS) in research based, faculty, and postdoctoral positions.

Study Design: Cross-sectional study, using 189 global institutions from the Center for Science and Technology Leiden ranking of world universities of 2017, including the U15 Group (Canadian Research-Intensive Universities), and five self-selected supplementary institutions.

Methods: The main outcome measure for our study is the level of OS in job advertisements, assessed using the Modified Open Science Modular Scheme.

The impact of gender on researchers' assessment: A randomized controlled trial.

Objectives: This randomized controlled trial aimed to test whether women or men would be preferred with identical curriculum vitae (CV); and the impact of the career stage in the evaluators' choice.

Study Design And Setting: A simulated post-doctoral process was carried forward to be assessed for judgment. Level 1 and 2 Brazilian fellow researchers in the field of Dentistry were invited to act as external reviewers in a post-doctoral process and were randomly assigned to receive a CV from a woman or a man.

The impact of gender on scientific writing: An observational study of grant proposals.

Objectives: This study aimed to determine whether there are differences in the language used in grant applications submitted to a Southern Brazil Research Support Foundation (FAPERGS) according to the gender, career stage, and the number of publications of applicants.

Study Design And Setting: This observational study also evaluated the relationship between gender, career stage, curriculum, and writing characteristics. Summaries of all research proposals in the biomedical field of FAPERGS during the years of 2013 and 2014 were evaluated according to six language patterns (Positive emotions, Negative emotions, Analytic thinking, Clout, Authenticity, and Emotional tone) defined by the LIWC software.

Transparency in clinical trials: Adding value to paediatric dental research.

Background: Even though considered as studies with high methodological power, many RCTs in paediatric dentistry do not have essential quality items in their design, development, and report, making results' reliability questionable, replication challenging to conduct, wasting time, money, and efforts, and even exposing the participants to research for no benefit.

Aim: We addressed the main topics related to transparency in clinical research, with an emphasis in paediatric dentistry.

Design: We searched for all controlled clinical trials published from January 2019 up to July 2020 in the three paediatric dentistry journals with high journal Impact Factor, indexed on Medline.

Factors affecting the color stability and staining of esthetic restorations.

This study aimed to assess the color stability of two composite resins, unprotected or protected with a hydrosoluble gel (oxygen inhibitor) during final polymerization, when subjected to different staining solutions and daily tooth brushing simulation. Nanohybrid composite (IPS Empress Direct) or nanofilled composite (Filtek Z350) were used to produce round samples that were either unprotected or protected with a hydrosoluble gel before the final cycle of polymerization. For 5 days, the samples were immersed for 1 h/day in four different staining solutions: distilled water (control), coffee, soft drink, and red wine.
