Revista Científica do CRO-RJ (Rio de Janeiro Dental Journal) | Instructions to authors

The Revista Científica do CRO-RJ (Rio de Janeiro Dental Journal), a periodical published quarterly aiming at divulging and promoting scientific production and interchange of information between the Brazilian and International community in the different areas of Dentistry and other fields of Health Care. The entire content of the Revista Científica do CRO-RJ (Rio de Janeiro Dental Journal) is available on the following web site http://revcientifica.cro-rj.org.br, to which there is free access. All the articles published in the Revista Científica do CRO-RJ (Rio de Janeiro Dental Journal) have a publication license CC BY-NC-ND (http://creativecommons.org/licenses/by-nc-nd).

The Revista Científica do CRO-RJ (Rio de Janeiro Dental Journal) publishes original articles, clinical case reports, reviews, letters to the editor and editorials/comments. Researches involving animals and/or human beings must be accompanied by the Certificate of Approval of a Research Ethics Committee. All articles are published in PDF format, in American English and must be submitted in this language. An abstract in Portuguese is demanded at the time of submitting and sending the final version.

Peer Review Process

All the content published by the Revista Científica do CRO-RJ (Rio de Janeiro Dental Journal) goes through the process of review by specialists. Articles submitted for appreciation are sent to the CRO-RJ librarian, who, under the supervision of the Editors-in Chief, initially assesses them with regard to the minimum standards demanded  relative to form of presentation in the Revista Científica do CRO-RJ (Rio de Janeiro  Dental  Journal), with a view to complying with all the guidelines required for sending original articles. Once approved at this stage, the original is submitted for appreciation by the Editorial Board, to assess the merit of the work and decide about the convenience of publishing it, with or without changes. After this, the article is sent to undergo a process of evaluation carried out in the review system, by peers selected from a register of reviewers. The reviewers are always professionals from institutions different from that of the origin of the article; they are blind to the identity of the authors and place of origin of the work. After receiving both reports, the Editorial Council evaluates them, and decides about acceptance of the article without changes, rejection, or return to the authors with the suggestions about changes.  The Editorial Board is responsible for returning the article to the authors for explanations, as many times as necessary, and at any time, the Editors may decide to reject the document. Each version is always analyzed by the Editorial Board that has the power of making the final decision.
