1. Peer review policy

All papers are subject to peer review, typically involving at least two independent, expert reviewers. RDE uses a double-blind process, where author and reviewer identities are concealed from each other but visible to the decision-making editor. Reviewers interact only with an editor, ensuring an 'independent review.' Reviewers must inform the Editor-in-Chief if they have a conflict of interest with the manuscript.

An initial decision is usually made within 6-8 weeks after reviewers agree to review. Reviewers must maintain confidentiality and cannot share manuscript details without prior permission from the Editor-in-Chief. Manuscripts are not returned to authors, regardless of the publication decision, and no review process details are published on the article page.

Manuscripts from editors, employees, or Editorial Board members are processed like other unsolicited manuscripts, with those authors excluded from the review and decision process. Editors do not handle their manuscripts, even if commissioned.

• Screening after submission
After submission, manuscripts undergo a screening process. If a manuscript does not fit the journal's aims and scope or fails to follow the guidelines for authors, it may be returned immediately without review. All submissions are checked for plagiarism using 'Similarity Check powered by iThenticate' (https://www.crossref.org/services/similarity-check/).

• Peer review process
Submitted manuscripts are reviewed by two or more field-specific reviewers who assess relevance, creativity, importance, academic significance, clarity, and medical ethics compliance. Reviewers make one of four recommendations: accept, minor revision, major revision, or reject. Authors should revise based on reviewer feedback and provide explanations for any noncompliance. The Editorial Board makes the final publication decision and may request further changes. Statistical editing is performed if necessary. Once rejected, the manuscript does not undergo another round of review.

• Appeals of decisions
Appeals against editorial decisions must be made within 2 weeks of the decision letter. Authors should contact the editor-in-chief with detailed reasons for the appeal. Appeals are discussed with at least one associate editor and, if needed, at a full editorial meeting. The process follows COPE guidelines (https://publicationethics.org/appeals). RDE does not consider second appeals.

• Postpublication discussions
To correct errors in published articles, the corresponding author should contact the journal’s editorial office with a detailed description of the proposed correction. Errors can be corrected through an erratum (publisher's errors), corrigendum (author's errors), or retraction.

2. Copyright & open access policy

• Copyright
Authors must declare that their work is original and that copyright is not breached. Copyright for all published material is owned by the Korean Academy of Conservative Dentistry. Each author must sign the authorship responsibility and copyright transfer agreement, attesting to authorship criteria. The corresponding author submits the Copyright Transfer Agreement form during submission. Authors must obtain and provide written permission for any previously published material. Submitted material will not be returned unless requested.

• Open access license
RDE is an open-access journal. Articles are distributed under the terms of the Creative Commons Attribution Non-Commercial License (http://creativecommons.org/licenses/by-nc/4.0/), which permits unrestricted noncommercial use, distribution, and reproduction in any medium, provided the original work is properly cited. Authors do not need permission to use tables or figures published in RDE in other periodicals, books, or media for noncommercial purposes. For any commercial use of material from this open-access journal, permission must be obtained from the Korean Academy of Conservative Dentistry (email: kacd@kacd.or.kr).

3. Article sharing policy

RDE is an open-access journal published under the terms of the Creative Commons Attribution Non-Commercial License (http://creativecommons.org/licenses/by-nc/4.0/), allowing articles to be shared freely without embargo.

• Accepted version
The accepted version, which incorporates all peer review amendments prior to final publication, may be shared on non-commercial websites and repositories. Authors who previously uploaded their article to a preprint server should update the preprint with the accepted manuscript following peer review.

• Published version
The final, published version can be shared immediately upon publication. Under the CC BY-NC 4.0 license, this version permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited.

4. Archiving policy

RDE ensures electronic backup and preservation of journal content through archiving in the National Library of Korea and PubMed Central from the 37th volume, 2012 (https://pmc.ncbi.nlm.nih.gov/journals/?term=%22Restorative+Dentistry+%26+Endodontics%22). This allows for permanent preservation of RDE papers and ensures access in the event the journal ceases publication.

5. Data sharing policy

RDE encourages data sharing wherever possible unless this is prevented by ethical, privacy, or confidentiality matters. Authors wishing to do so may deposit their data in a publicly accessible repository and include a link to the DOI within the text of the manuscript. RDE accepts the ICMJE Recommendations for data sharing statement policy (https://www.icmje.org/recommendations/). All manuscripts reporting clinical trial results should submit a data sharing statement following the ICMJE guidelines. Authors may refer to the editorial, “Data Sharing Statements for Clinical Trials: A Requirement of the International Committee of Medical Journal Editors,” in the Journal of Korean Medical Science (https://doi.org/10.3346/jkms.2017.32.7.1051).

6. Preprint policy

RDE is open to the possibility of publishing manuscripts containing information initially shared on reputable non-profit preprint platforms, such as medRxiv, bioRxiv, arXiv, ScienceOpen, and ResearchSquare. It is necessary for authors to retain the copyright to posted preprints. Disclosure of preprint details is required during the submission process for reviewers and editors to be able to assess the preprint content and compare it to the submitted text. Articles undergoing peer review should not be uploaded to preprint servers. Upon acceptance, it is necessary for the authors to acknowledge publication in RDE by adding a link to the published version in any earlier posted versions of the manuscript, using the following text: “This article has been published in Restorative Dentistry and Endodontics after undergoing peer review and can also be viewed on the website at [insert DOI].”

7. Disclosure of generative AI in scientific writing

When authors use generative artificial intelligence (AI) and AI-assisted technologies in the writing process including figures, images and artwork, they should limit their use to enhance readability and language. Please be aware that authors are ultimately responsible and accountable for the content. As AI can produce authoritative-sounding content that may be incorrect, incomplete, or biased, authors must carefully review and edit the results. AI and AI-assisted technologies should not be credited as authors or co-authors, nor should they be cited as authors. Authors should disclose their use of AI and AI-assisted technologies in the writing process within their manuscript. A statement will be included in the published work.

8. Advertising policy

RDE accepts advertising and sponsorship according to the following principles:

• • Advertising is separate from content. Advertisers and sponsors have no advanced knowledge of our editorial contents, nor do the editors have advanced knowledge of advertisers. Content is never altered, added, or deleted to accommodate advertising. Advertisers and sponsors have no input regarding any of our editorial decisions or advertising policies.
• • We reserve the right to decline or cancel any advertisement at any time.
• • Advertisements for pharmaceutical products must conform to all regulations and policies of the Ministry of Food and Drug Safety, Republic of Korea in every respect.

9. Registration of clinical trial research

All research involving clinical trials must be registered with a primary national clinical trial registry, such as the Korea Clinical Research Information Service (CRiS, http://cris.nih.go.kr), another primary national registry accredited by the World Health Organization (https://www.who.int/clinical-trials-registry-platform/network), or ClinicalTrials.gov (http://clinicaltrials.gov), a service of the United States National Institutes of Health.
