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, 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 (

The Revista Científica do CRO-RJ (Rio de Janeiro Dental Journal) publishes original articles, clinical case reports, protocols, 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.

Discussion: This must interpret the results and compare them with data previously described in the literature, emphasizing the new and important aspects of the study. Discuss the implications of the findings and their limitations, as well as the need for additional researches. Avoid repetition of the results and/or superimposition between results and discussion. The conclusions must be presented at the end of the discussion, and must respond to the aims of the study, by avoiding information if inferences were not supported by the findings. The authors must place equal emphasis on favorable and unfavorable findings that have similar scientific merits. Include recommendations, when these are pertinent.

Conclusion: The conclusion section must correlate the main ideas of the review with the possible clinical applications, limiting generalization to the domains of the review.

- In cases of systematic reviews, with or without meta-analyses,        the       authors must follow the PRISMA statement ( These reviews must contain: Introduction: that demonstrates the pertinence of the subject and the existent controversy with respect to the topic. At the end of the introduction, the authors should raise the focal question of the review. Materials and Methods: must present the search strategy; eligibility criteria of the studies; risk of bias analysis of the included studies; data extraction, and when pertinent, the strategy used for quantitative data synthesis.

Result: must respond in an orderly manner to the data searched according to the methodological design with respect to the qualitative and quantitative synthesis of the primary studies included.

Discussion: must consider interpreting the results, emphasizing resolution of the controversies related to the topic, with this being directed towards answering the focal question of the review, showing whether or not there is need for further research.
