Human and animal research

All researchers must ensure that the conduction for research in humans is in accordance with the Declaration of Helsinki and in accordance with the 2013 review of the document. All authors must seek approval to conduct research from an independent local, regional, or national review committee — such as a Regional Board of Dentistry or an ethics committee.

If there is any doubt as to whether the research was conducted in accordance with the statement, the authors should explain the reason for their approach and demonstrate that the review committee has explicitly approved aspects that may be questionable in relation to the study. Approval by a responsible review committee does not preclude Dental Press Publishing editors from making their own judgment as to whether the conduct of the research was appropriate. When reporting animal experiments, authors should indicate whether institutional and national standards for the care and use of laboratory animals have been followed. Additional guidelines, adopted by Dental Press Publishing, on ethics in animal research are available in the Guidelines for Authors, Consensus on Ethics and Animal Welfare, of the International Association of Veterinary Publishers, at the following link:

Informed consent policy 

For all research involving human participants, informed consent to participate in the study should be obtained from participants (or their parent or legal guardian in the case of children under 16) and a statement to this effect should appear in the manuscript. Consent must be obtained for all forms of personally identifiable data. Documentary evidence of consent must be supplied if requested.

Corrections and retractions

Corrections to, or retractions of, published articles will be made by publishing a Correction or a Retraction note bidirectionally linked to the original article. Any alterations to the original article will be described in the note. The original article remains in the public domain and the subsequent Correction or Retraction will be widely indexed. In the exceptional event that material is considered to infringe certain rights or is defamatory, we may have to remove that material from our site and archive sites.

Authors, readers or organizations who become aware of errors or ethics issues in a published article are encouraged to contact the individual journal in the first instance via the contact details available on the journal website. All reports will be considered by the Editors; additional expert advice may be sought when deciding on the most appropriate course of action. Dental Press Publishing provides support to Editors in addressing publication ethics issues in a COPE (Committee on Publication Ethics)-compliant manner.


Changes to published articles that affect the interpretation and conclusion of the article, but do not fully invalidate the article, will, at the Editor(s)’ discretion, be corrected via publication of a Correction that is indexed and bidirectionally linked to the original article.


On rare occasions, when the interpretation or conclusion of an article is substantially undermined, it may be necessary for published articles to be retracted. Dental Press Publishing will follow the COPE guidelines in such cases. Retraction notices are indexed and bidirectionally linked to the original article. The original article is watermarked as retracted and the title is amended with the prefix “Retracted article:”

Editorial Expressions of Concern

When an Editor becomes aware of serious concerns regarding interpretation or conclusion of a published article, they may choose to publish a statement alerting the readership. Scenarios in which Editorial Expressions of Concern may be published include prolonged investigations of very complex cases and when the concerns may have a significant and immediate impact on public health or public policy. An Editorial Expression of Concern may be superseded by a subsequent Correction or Retraction, but will remain part of the permanent published record.
