Author Guidelines | Turkish Endodontic Journal

Guide for Authors

1. Aims and Scope

Turkish Endodontic Journal (TEJ) is the official scientific publication of Turkish Endodontic Society and open access, peer-reviewed international journal. TEJ is published three times per year (May, August, December). The authors are invited to submit original scientific articles, case reports, review articles regarding endodontology and dental traumatology. Letter to the Editor section is also available for authors to write a comment letter on a previously published article in the journal.

TEJ does not charge authors or authors’ institutions to submit, process or publish articles. There is no fee for extra pages or color images.

2. Editorial Policies and Ethical Considerations

The acceptance criteria for all articles are the article’s quality, originality and its significance to our readership. Except where otherwise stated, manuscripts are peer-reviewed by two anonymous reviewers and the Editor. The final decision is given by the Editorial Board, which reserves the right to refuse any material for publication.

Manuscripts should be written in a clear, concise, direct style. Editor-in-Chief or the Editorial Board reserves the right to change the format, grammar, or sentence structure of any part of the manuscript to comply with the guidelines to fit the standard format and journal style.


TEJ strictly adheres to the International Committee of Medical Journal Editors (ICMJE) standards to define the authorship qualifications. We recommend that an author should provide ALL of the following four criteria:

 (1) Substantial contributions to the conception or design of the work; or the acquisition, analysis, or interpretation of data for the work;

 (2) Drafting the work or revising it critically for important intellectual content;

 (3) Final approval of the version to be published;

 (4) Agreement to be accountable for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of the work are appropriately investigated and resolved.

Contributors who do not qualify as authors should be mentioned under ‘Acknowledgements’.

Authors should take collective responsibility for their work and the content of their publications. Corresponding author should submit Authors Contribution Form before proceeding with further submission and evaluation processes.

6. Publication Process after Acceptance

If your paper is accepted, the author identified as the formal corresponding author will receive an email prompting them to log in to Author Services and they will be required to complete a copyright license agreement on behalf of all authors of the paper.

Once the paper has been typeset, the corresponding author will receive an email alert containing proof to be checked and corrected before publication within seven days. It is, therefore, essential that a working email address is provided for the corresponding author. Proofs should be corrected carefully; responsibility for detecting errors lies with the author.

Articles will generally appear in the order in which they were accepted as publication; however, Editor-in-Chief and Editorial Board reserve the right to modify this schedule in the presence of critical scientific issues.

DOI number

Digital Object Identifier (DOI) number is a unique alphanumeric identifier assigned by a registration agency. Once it is assigned to an article, the DOI will never change; therefore, it is ideal for citing and linking electronic documents. Your article will be assigned a DOI number provided by the CrossRef registration agency.

Correction, Retraction & Removal

A formal correction will be issued in the journal by the Editor-in-Chief if only a small portion of otherwise reliable article is flawed in a way that does not severely affect the findings reported in it (such as mistakes in the spelling of a drug, miscalculation of a formula, mismatch between images and their captions or incorrect author list). Online articles will not be corrected directly. An erratum (for publishing error) or a corrigendum (for author error) will be published in the next issue of the journal.

Articles may be retracted by its authors or by the Editor-in-Chief under the advice of the scientific community. If authors are willing to retract an article before publication(accepted or under review), requests must be sent to the Editor-in-Chief from the corresponding author of the manuscript. This document must include the reason the article should be retracted and written confirmation (email, fax, letter) from all authors that they agree on the retraction. A formal retraction announcement written by the Editor-in-Chief will be published.
