Policy of Screening for Plagiarism

Plagiarism Screening

Bali Dental Journal — Originality Verification and Integrity Standards

Bali Dental Journal (BDJ) is committed to publishing only original research. All manuscripts submitted to BDJ are screened for plagiarism prior to peer review using dedicated plagiarism detection software. Manuscripts that contain unacceptable levels of similarity with previously published work, without proper attribution, will be rejected without peer review.

Screening Process

All submitted manuscripts undergo plagiarism screening using industry-standard software (such as iThenticate or Turnitin) at the editorial stage, before being sent for peer review. The screening checks for textual similarity against a broad database of published articles, books, conference proceedings, theses, and internet content.

Similarity Level

Editorial Action

0 – 20% (overall similarity)

Acceptable. Proceeds to peer review.

21 – 30% (overall similarity)

Borderline. Editor reviews sources; author may be asked to revise and resubmit.

Above 30% (overall similarity)

Rejected outright without peer review.

Note: Similarity percentages are assessed on the overall manuscript. A high match to a single source (e.g., more than 5% from one source) may also trigger concern, even if the total similarity is below 20%. Context is considered: similarity from properly cited quotations, reference lists, and standard methods sections is evaluated differently from similarity in the results or discussion sections.

Forms of Plagiarism

BDJ considers the following to be forms of plagiarism, all of which are unacceptable:

Direct Plagiarism

Copying text word-for-word from another source without quotation marks and citation.

Self-Plagiarism

Reusing substantial portions of one's own previously published work without disclosure, citation, or permission.

Paraphrasing Plagiarism

Restating another author's ideas in different words without proper attribution.

Mosaic Plagiarism

Piecing together text from multiple sources, with or without minor rewording, without attribution.

Data Duplication

Submitting data, figures, or results that have already been published elsewhere as part of a new manuscript without disclosure.

AI-Generated Content (Undisclosed)

Presenting text generated by an AI tool as one's own original writing without disclosure, which constitutes a form of academic dishonesty.

Author Responsibilities

Authors are expected to screen their own manuscripts for originality before submission. Recommended tools include iThenticate, Turnitin, Grammarly, or similar software. BDJ recommends that authors ensure a similarity index of less than 20% on their final submitted draft.

Authors must honestly represent all sources, including their own prior work. Prior publications that overlap substantially with the submitted manuscript must be cited and disclosed in the cover letter.

By submitting to BDJ, authors confirm that the manuscript represents original, unpublished work and that all sources have been properly cited.

Post-Publication Plagiarism Detection

If plagiarism is detected in a published article, BDJ will investigate in accordance with COPE guidelines. Depending on the severity of the violation, actions may include issuance of a Correction, Expression of Concern, or formal Retraction of the article. Retracted articles remain visible on the BDJ website with a clear retraction notice attached.

Suspicion of plagiarism or misconduct in any BDJ publication may be reported to the Editor-in-Chief. All reports are treated confidentially and investigated systematically.
