Objectives: To quantify, characterize and analyze e-mail from predatory journals (PJ) received by an academic in dentistry.

Methods: E-mails received in 2019 and suspected of being potentially predatory were pre-selected. The Ottawa Hospital Research Institute (OHRI) checklist was applied to identify the suspected biomedical PJ, including the following criteria: article processing charge (APC), fake impact factor, the journal being listed in the Directory of Open Access Journals (DOAJ) and the Committee on Publication Ethics (COPE). We also extracted information on the lack of an impact factor on Journal Citations Reports, non-journal affiliated contact e-mail address, flattering language, article and/or personal citation, unsubscribe link, being listed in the National Library of Medicine (NLM) current catalog and indexed on Medline.

Results: A total of 2,812 unsolicited suspected e-mails were received, and 1,837 requested some sort of manuscript; among these, 1,751 met some of the OHRI criteria. Less than half (780/1,837, 42%) referred to some area of dentistry. The median APC was US$399. A false impact factor was mentioned in 11% (201/1,837) of the e-mails, and 27% (504/1,837) corresponded to journals currently listed in the NLM catalog. Journals listed in DOAJ and COPE sent 89 e-mails.

Conclusions: The email campaign from PJs was high and recurrent. Researchers should be well informed about PJs' modus operandi to protect their own reputation as authors and that of science.

Clinical Significance: Peer review and established academic practices and etiquette contribute to ensuring scientific progress, which is essential to protect the health of patients in particular and of people in general. Predatory journals constitute a threat to peer review and scientific etiquette and, as such, may hinder scientific progress and public health.

Fluoride Varnish and Dental Caries in Preschoolers: A Systematic Review and Meta-Analysis.

Caries Res 2019 20;53(5):502-513. Epub 2019 Jun 20.

Department of Community and Preventive Dentistry, School of Dentistry, Rio de Janeiro State University, Rio de Janeiro, Brazil.

The aim of this study was to assess the effectiveness of fluoride varnish (FV) in reducing dentine caries at the patient, tooth, and surface levels as well as caries-related hospitalizations in preschoolers. We performed a systematic review of clinical trials of FV, alone or associated with an oral health program, compared with placebo, usual care, or no intervention. Bibliographical search included electronic searches of seven databases, registers of ongoing trials, and meeting abstracts, as well as hand searching. We performed random-effects meta-analyses and calculated confidence and prediction intervals. The search yielded 2,441 records; 20 trials were included in the review and 17 in at least one meta-analysis. Only one study had low risk of bias in all domains. We found no study reporting on caries-related hospitalizations. At the individual level, the pooled relative risk was 0.88 (95% confidence interval [CI] 0.81, 0.95); this means that in a population of preschool children with 50% caries incidence, we need to apply fluoride varnish in 17 children to avoid new caries in one child. At the tooth level, the pooled weighted mean difference was -0.30 (95% CI -0.69, 0.09) and at the surface level -0.77 (95% CI -1.23, -0.31). Considering the prediction intervals, none of the pooled estimates were statistically significant. We conclude that FV showed a modest and uncertain anticaries effect in preschoolers. Cost-effectiveness analyses are needed to assess whether FV should be adopted or abandoned by dental services.
