Submitted manuscripts should not contain any previously published materials and should not be under consideration for publication elsewhere.
A manuscript that is potentially redundant includes the following characteristics:
(1) at least one of the authors has contributed to both or all reports (if there are no common authors, plagiarism is more likely than redundant publication);
(2) the subject or study populations are often the same or similar;
(3) the methodology is typically identical or nearly so; and
(4) the results and their interpretation generally vary little, if at all.
If authors believe their manuscript may be redundant, they should ask the editor about this in a cover letter accompanying their submission and should clearly state the reuse/overlap of study materials in Materials and Methods of the manuscript.
In the letter, the manuscript authors should explain how their report overlaps with already published material, or how it differs.
To help the editor determine the possibility of redundant publication, a copy of such material previously published or being considered for publication elsewhere should be included. Any investigations involving humans and animals should be approved by the Institutional Review Board and Animal Care Committee, respectively, of the institution where the study took place.
The Journal of the Korean Academy of Pediatric Dentistry will not consider any studies involving humans or animals without the appropriate approval. Informed consent should be obtained, unless waived by the institutional review board, from patients who participated in clinical investigations.
Original articles submitted to the Journal of the Korean Academy of Pediatric Dentistry, which address any investigation involving humans and animals should include a description about whether the study was conducted under an approval by the Institutional Review Board (with or without patient informed consent) and Animal Care Committee, respectively, of the institution where the study was conducted.
The Journal of the Korean Academy of Pediatric Dentistry can request an approval by Institutional Review Board or Animal Care Committee for the other types of articles when necessary.
For the policies on the research and publication ethics not stated in these instructions, "Good Publication Practice Guidelines for Medical Journals (http://kamje.or.kr/publishing_ethics.html)" or "Guidelines on good publication (http://www.publicationethics.org.uk/guidelines)" can be applied.
Descriptions appearing in each article are the responsibility of the authors and not of the Journal of the Korean Academy of Pediatric Dentistry.
