Abstract
Background: Brazil is a rich resource in oral health research largely as a result of its many dental schools. Much of this research is not indexed to the larger international databases and thus is not available to the global community. Some reports of trials may have also been ‘buried’ as a result of indexing bias, lack of cover-to-cover indexing, or language bias. Objectives: To provide a comprehensive report of the number and scope of Brazilian dental journals which are currently in publication in addition to those that have ceased publishing. Data retrieved will be the foundation for future handsearching strategies of these journals as well as transmit reports of trials to the Cochrane Oral Health Group for inclusion in the CENTRAL database. Methods: The following databases were searched by two investigators: Qualis System; Brazilian Dental Bibliography; LILACS; Bireme’s Catalogue of Scientific Journals; SciELO; PubMed and Web of Science. Only those with a focus on general dentistry or dental specialty or on related topics were included. Journals were summarized according to geographic location, and investigated according to indexing, final publication year (if applicable), language and frequency. A questionnaire was sent to the editor of all journals seeking information on total or partial funding, type of funding (grants, government, advertisements, subscriptions), number of referees, country of residence of referees, and journals major problems. Results: One-hundred and sixty-nine oral health journals were included. They are concentrated in the states of Sao Paulo (52), Parana(12), Rio de Janeiro (12) and Rio Grande do Sul (11). Most journals were related to a University or to dental associations. Further variables are to be collected but preliminary results confirm that the majority of the journals were written in Portuguese and are not indexed in PubMed or Scielo. Conclusions: There is a vast number of oral health journals published in Brazil concentrated in the southeastern and southern portion of the country which are the most developed regions. Handsearching of these journals has the potential of unveiling a significant number of reports of trials which could provide value sources of evidence for Cochrane reviews.
