Editorial Process

Submissions are assessed by the Editorial Board and, if necessary, are subject to external peer-review using the double-blind method whereby the authors are blinded to the identity of the reviewers and editors.

Plagiarism Detector‘s main task is the automated detection of digital plagiarism (that is unauthorized copy-paste of textual material) that originated from the world wide web. It was designed to use the biggest digital publicly open database in the world.

Preprint Policy

Please find the P4 preprint policy here.

This journal accepts articles previously published on preprint servers.

Periodontology 4 will consider for review articles previously available as preprints. The authors may also post the submitted version of a manuscript to a preprint server at any time. The authors are requested to update any pre-publication versions with a link to the final published article.

For help with submissions, please contact: office@periodontology.com


The aim of the Periodontology 4 is to provide the platform for the exchange of scientific and clinical progress in the field of Periodontology and allied disciplines and to do so at the highest possible level. The Journal also aims to facilitate the application of new scientific knowledge to the daily practice of the concerned disciplines and addresses both practicing clinicians and academics. The Journal is the official publication of the European Federation of Periodontology but wishes to retain its international scope.

Periodontology 4 publishes original contributions of high scientific merit in the fields of Periodontology and Implant Dentistry. Its scope encompasses the physiology and pathology of the periodontium, the tissue integration of dental implants, the biology and the modulation of periodontal and alveolar bone healing and regeneration, diagnosis, epidemiology, prevention and therapy of periodontal disease, the clinical aspects of tooth replacement with dental implants, the comprehensive rehabilitation of the periodontal patient, periodontal surgeries, and biomaterials. Review articles by experts on new developments in basic and applied periodontal science and associated with dental implants, advances in periodontal or implant techniques and procedures, and case/series reports which illustrate important new information are also welcome.


Periodontology 4 publishes original research articles, clinical innovation trials/reports, case reports/series, and reviews. The latter will be published only if they provide new fundamental knowledge and if they use language understandable to the clinician. It is expected that any manuscript submitted represents unpublished original research.

a. Original Research Articles

Original research articles must describe significant and original experimental observations and provide sufficient detail so that the observations can be critically evaluated and, if necessary, repeated. Original articles will be published under the heading of periodontology, implant dentistry, pre-clinical sciences, and must conform to the highest international standards in the field.

Word limit: 4,000 words maximum, excluding references and abstract. Abstract: 250 words maximum; it must be structured, under the sub-headings: Objective(s), Materials and Methods, Results, and Conclusion(s). Figures/Tables: Total of no more than 8 figures and tables.

Introduction: should be focused, outlining the historical or logical origins of the study and not summarize the results; exhaustive literature reviews are not appropriate. It should close with the explicit statement of the specific aims of the investigation.

Material and Methods: must contain sufficient detail such that, in combination with the references cited, all clinical trials and experiments reported can be fully reproduced, and prior approved by the Ethics Committee. As a condition of publication, authors are required to make materials and methods used freely available to academic researchers for their own use.

Results: should present the observations with minimal reference to earlier literature or to possible interpretations.

Discussion: it may usefully start with a brief summary of the major findings, but the repetition of parts of the abstract or of the results section should be avoided. Statements and interpretation of the data should be appropriately supported by original references.

Conclusion(s): it should do a brief conclusion and a comment on the potential clinical relevance of the findings.

  • Summary of the key finding: Primary outcome measure(s); Secondary outcome measure(s); Results as they relate to a prior hypothesis.
  • Strengths and Limitations of the Study: Study Question; Study Design; Data Collection; Analysis; Interpretation; Possible effects of bias on outcomes.
  • Interpretation and Implications in the context of the totality of evidence: Is there a systematic review to refer to?; If not, could one be reasonably done here and now?; What this study adds to the available evidence; Effects on patient care and health policy; Possible mechanisms.
  • Controversies Raised by This Study Future Research Directions: For this particular research collaboration; Underlying mechanisms; Clinical research.

b. Clinical Innovation Trials/Reports 

Clinical innovation trials/reports are suited to describe significant improvements in clinical practice such as the report of a novel surgical technique, a breakthrough in technology or practical approaches to recognized clinical challenges. They should conform to the highest scientific and clinical practice standards.

Word limit: 3,500 words maximum, excluding references and abstract. Abstract: 180 words maximum; it must be structured, under the sub-headings: Objective(s), Clinical Trial/Report, and Conclusion(s). Main text: should be organized following with the Introduction; Clinical Innovation Trial/Report; Discussion, and Conclusion. Figures/Tables: Total of no more than 12 figures and tables.

c. Case Reports/Series

Case Reports/Series illustrating unusual and clinically relevant observations are acceptable, but their merit needs to provide high priority for publication in the Case Reports P4 Journal. On rare occasions, completed cases displaying non-obvious solutions to significant clinical challenges will be considered.

Word limit: 2,000 words maximum, excluding references and abstract. Abstract: 180 words maximum; it must be structured, under the sub-headings: Objective(s), Case Report/Series, and Conclusion(s). Main text: should be organized with Introduction; Case report/Series; Discussion and Conclusion. Figures/Tables: Total of no more than 15 figures and tables.

d. Reviews

Reviews are selected for their broad general interest; all are refereed by experts in the field who are asked to comment on issues such as timeliness, general interest, and balanced treatment of controversies, as well as on scientific accuracy. Reviews should take a broad view of the field rather than merely summarizing the authors’ own previous work, so extensive citation of the authors’ own publications is discouraged.

Wherever possible, reviews should be constructed and submitted as Systematic Reviews, or at the very least provide robust descriptions of the methods that would allow readers to reproduce these. The use of state-of-the-art evidence-based systematic approaches is expected.

Reviews are frequently commissioned by the editors and, as such, authors are encouraged to submit a proposal to the P4 Journal. Review proposals should include a full-page summary of the proposed contents with key references.

Note: For Systematic Reviews, the Journal adheres to the PRISMA reporting guidelines – PRISMA checklists should be included in submissions and it is expected the register in the PROSPERO platform.

Word limit: 5,000 words maximum, excluding references and abstract. Abstract: 300 words maximum; it must be structured, under the sub-headings: Objective(s), Materials and Methods, Results, and Conclusion(s). Main text: should be organized with Introduction; Review; Discussion and Conclusion. Figures/Tables: Total of no more than 8 figures and tables.

E. Editorial and Letters to the Editor

Even though they are not the focus of Periodontology 4, this type of articles are also accepted. The EDITORIAL should provide commentary and analysis concerning an article in the issue of the Journal in which they appear. It may include figures and tables (up to 4). It is always solicited. The editorials would be limited to 1000 words with up to 10 references.

The Letters to the Editor should raise some issues related to recently published articles (in the last 6 months) in Periodontology 4. The letters should not exceed (1000 words) of text and up to 5 references. While not all “Letters to the Editor” will be published, those that are judged worthwhile will be forwarded to the authors of the articles in question or to selected experts in order to provide the opportunity for a response. Whenever possible, they will be published with the reply of the author of the published article.

Revisions and Resubmissions: Please note that all revisions and resubmissions of papers should also include a separate rebuttal and a tracked changes document to assist in peer-review.


Manuscript submission: must be submitted by the P4’s submission system, in Word (.doc/.docx) or Rich Text Format (.rtf) files (not write-protected) plus separate TABLE(S) and FIGURE(S) files (high-resolution of JPG, JPEG, JPE, TIF, or TIFF). For some parts of the submission, it will be requested a ZIP file with all documents (pay attention during the submission).

One text file must include only the title page, for double-blind review. Another text file must contain the entire manuscript including the abstract (with the title above), text, references, and figure legends. Another text file per table. Manuscripts should be formatted as described in the Author Guidelines below.

Please note that all unpublished papers (submitted or in press) included in the reference list should be provided in a digital version at submission. The unpublished paper should be uploaded as a supplementary file for review.

Figure Legends: Legends should be concise but comprehensive. The figure and its legend must be understandable without reference to the text. Include definitions of any symbols used and define/explain all abbreviations and units of measurement.


The authors are encouraged to send the highest-quality figures possible, for peer-review purposes, in JPG, JPEG, JPE, TIF, TIFF formats. The legends or captions, under the figure, should use Arabic numerals, follow the order in which they appear in the manuscript, and explain any abbreviations or symbols that appear in the figure. The file naming should be to facilitate ease of review, naming the figure files only with the word “figure” and the appropriate number (e.g., Figure1.tif”).

  • Include your figure legends as a separate section in your main text file, numbered in Arabic sequentially;
  • Ensure all figures are numbered in the order in which they appear;
  • Follow the high resolution for the best presentation, because higher-quality figures are more useful to readers;
  • Use the preferred file types for the best image quality. If in doubt, write for office@periodontology4.com;
  • Remove excess white space surrounding figures for smaller file sizes;
  • Using only figure numbers in the file names ensures correct typesetting.

Image size: For small images – 80 mm canvas size or Pixel dimensions (width): 1800px minimum; for large images – 180 mm canvas size or Pixel dimensions (width): 1800px minimum.

Resolution: For Line arts (larger fonts make for easier reading): 600-1000 dpi; Images: 300-600 dpi.

Colour Figures. Figures submitted in colour may be reproduced in colour online free of charge. Please note, however, that it is preferable that line figures (e.g. graphs and charts) are supplied in black and white so that they are legible by a reader in black and white.


Tables should be self-contained and complement, not duplicate, the information contained in the text. They should be supplied as editable text files, not pasted as images. Legends should be concise but comprehensive – the table, legend, and footnotes must be understandable without reference to the text. All abbreviations must be defined in footnotes.

Footnote symbols: †, ‡, §, ¶ should be used (in that order) and *, **, *** should be reserved for significant P-values. Statistical measures such as SD or SEM should be identified in the headings.


The authors will be asked to provide a conflict of interest statement (title page) during the submission process, and a single text file with all conflict for each author. All authors must disclose any financial and personal relationships with other people or organizations that could inappropriately influence (bias) their work.

Examples of potential competing interests include employment, consultancies, stock ownership, honoraria, paid expert testimony, patent applications/registrations, and grants or other funding. Authors must disclose any interests in two places:

1. A summary declaration of interest statement in the title page file after acknowledgments. If there are no interests to declare then please state this: ‘Declarations of interest: none’. This summary statement will be ultimately published if the article is accepted.

2. Detailed disclosures as part of a separate Declaration of Interest form, which forms part of the journal’s official records. It is important for potential interests to be declared in both places and that the information matches. Submitting authors should ensure they liaise with all co-authors to confirm agreement with the final statement. Authors are required to disclose all sources of funding for their research and any possible conflict of interest. These include financial conflict of interests (for example patent, ownership, stock ownership, consultancies, speaker’s fee).

The above policies are in accordance with the Uniform Requirements for Manuscripts Submitted to Biomedical Journals produced by the International Committee of Medical Journal Editors (http://www.icmje.org/). It is the responsibility of the corresponding author to have all authors of a manuscript fill out a conflict of the interest disclosure form, and to upload all forms together with the manuscript on submission. Please find the form below: Conflict of Interest Disclosure Form


Appendices/Supplementary material: it will be published after the figure(s) legend. For submission, they should be supplied as separate files but referred to in the text.

Supporting Information: It is information that is not essential to the article but provides greater depth and background. It is hosted online and appears without editing or typesetting. It may include tables, figures, videos, datasets, etc.

If data, scripts, or other artifacts used to generate the analyses presented in the paper are available via a publicly available data repository, authors should include a reference to the location of the material within their paper.

General Style Points: The following points provide general advice on formatting and style.

  • Abbreviations, Symbols, and Nomenclatures: Periodontology 4 adheres to the conventions outlined in Units, Symbols, and Abbreviations: A Guide for Medical and Scientific Editors and Authors. Abbreviations must be completely written in the text when first used. After, only use the abbreviation.

Article Preparation: It is strongly encouraged to review the article with an expert in the English Language, as well as correct translation(s), manuscript formatting, figure illustration/formatting, and graphical abstract design. Afterward, you can submit your manuscript with confidence.
Also, check out all the AUTHOR guidance about writing and preparing your manuscript.


Peer Review and Acceptance: The acceptance criteria for all papers are the quality and originality of the research and its significance to journal readership. Manuscripts are single-blind peer-reviewed. Papers will only be sent to review if the Editor-in-Chief determines that the paper meets the appropriate quality and relevance requirements or within the journal’s scope.

The appeal of decision: Under exceptional circumstances, authors may appeal to the editorial decision. Authors who wish to appeal the decision on their submitted paper may do so by e-mailing the editorial office at office@periodontology4.com with a detailed explanation for why they find reasons to appeal the decision.

Please note that all revisions and resubmissions of papers should also include a separate rebuttal and a tracked changes document to assist in peer review.

Human Studies and Subjects: For manuscripts reporting studies that involve human participants, a statement identifying the ethics committee that approved the study and confirmation that the study conforms to recognized standards is required, for example, Declaration of Helsinki; US Federal Policy for the Protection of Human Subjects, or European Medicines Agency Guidelines for Good Clinical Practice. It should also state clearly in the text that all persons gave their informed consent prior to their inclusion in the study. It is encouraged to attach as supplementary material, the letter of approval of the ethics committee, which can be requested by the editors.

Patient anonymity should be preserved. When detailed descriptions, photographs, or videos of faces or identifiable body parts are used that may allow identification, authors should obtain the individual’s free prior informed consent. The authors do not need to provide a copy of the consent form to the publisher. However, in signing the author’s license to publish, authors are required to confirm that consent has been obtained. P4 has a standard Patient Consent Form available for use. Where photographs are used they need to be cropped sufficiently to prevent human subjects being recognized; black eye bars should not be used as they do not sufficiently protect an individual’s identity.

Animal Studies: A statement indicating that the protocol and procedures employed were ethically reviewed and approved, as well as the name of the body giving approval, must be included in the Methods section of the manuscript. Authors are encouraged to adhere to animal research reporting standards, for example, the ARRIVE guidelines for reporting study design and statistical analysis; experimental procedures; experimental animals and housing, and husbandry. Authors should also state whether experiments were performed in accordance with relevant institutional and national guidelines for the care and use of laboratory animals:

Clinical Trial Registration: The journal requires that clinical trials are prospectively registered in a publicly accessible database and clinical trial registration numbers should be included in all papers that report their results. The authors are asked to include the name of the trial register and the clinical trial registration number at the end of the abstract. If the trial is not registered or was registered retrospectively, the reasons for this should be explained.

Research Reporting Guidelines: Accurate and complete reporting enables readers to fully appraise research, replicate it, and use it. The authors are required to adhere to recognized research reporting standards. The EQUATOR Network collects more than 370 reporting guidelines for many study types, including for:

Species Names: Upon its first use in the title, abstract, and text, the common name of a species should be followed by the scientific name (genus, species, and authority) in parentheses. For well-known species, however, scientific names may be omitted from article titles. If no common name exists in English, only the scientific name should be used.

Genetic Nomenclature: Sequence variants should be described in the text and tables using both DNA and protein designations whenever appropriate. Sequence variant nomenclature must follow the current HGVS guidelines; see varnomen.hgvs.org, where examples of acceptable nomenclature are provided.

Sequence Data: Nucleotide sequence data can be submitted in the electronic form to any of the three major collaborative databases: DDBJ, EMBL, or GenBank. It is only necessary to submit to one database as data are exchanged between DDBJ, EMBL, and GenBank on a daily basis. The suggested wording for referring to accession-number information is: ‘These sequence data have been submitted to the DDBJ/EMBL/GenBank databases under accession number U12345’. Addresses are as follows:

Proteins sequence data should be submitted to either of the following repositories:

Structural Data: For papers describing structural data, atomic coordinates and the associated experimental data should be deposited in the appropriate databank (see below). Please note that the data in databanks must be released, at the latest, upon publication of the article. We trust in the cooperation of our authors to ensure that atomic coordinates and experimental data are released on time.

  • Organic and organometallic compounds: Crystallographic data should not be sent as Supporting Information, but should be deposited with the Cambridge Crystallographic Data Centre (CCDC) at ccdc.cam.ac.uk/services/structure%5Fdeposit.
  • Inorganic compounds: Fachinformationszentrum Karlsruhe (FIZ; fiz-karlsruhe.de).
  • Proteins and nucleic acids: Protein Data Bank (rcsb.org/pdb).
  • NMR spectroscopy data: BioMagResBank (bmrb.wisc.edu).

Statistical Analysis: As papers frequently provide insufficient detail as to the performed statistical analysis, please describe with adequate detail. For clinical trials intention to treat analysis is encouraged (the reasons for choosing other types of analysis should be highlighted in the submission letter and clarified in the manuscript).

Funding: Authors should list all funding sources at submission. The authors are responsible for the accuracy of their funder designation. If in doubt, please check the Open Funder Registry for the correct nomenclature: https://www.crossref.org/services/funder-registry/

Authorship: The journal follows the ICMJE definition of authorship, which indicates that authorship is based on the following 4 criteria:

  1. Substantial contributions to the conception or design of the work; or the acquisition, analysis, or interpretation of data for the work; AND
  2. Drafting the work or revising it critically for important intellectual content; AND
  3. Final approval of the version to be published; AND
  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.

In addition to being accountable for the parts of the work he/she has done, an author should be able to identify which co-authors are responsible for specific other parts of the work. In addition, authors should have confidence in the integrity of the contributions of their co-authors.

All those designated as authors should meet all four criteria for authorship, and all who meet the four criteria should be identified as authors. Those who do not meet all four criteria should be acknowledged. These authorship criteria are intended to reserve the status of authorship for those who deserve credit and can take responsibility for the work. The criteria are not intended for use as a means to disqualify colleagues from authorship who otherwise meet authorship criteria by denying them the opportunity to meet criterion #s 2 or 3. Therefore, all individuals who meet the first criterion should have the opportunity to participate in the review, drafting, and final approval of the manuscript.

Human subject information in databases. The journal refers to the World Health Medical Association Declaration of Taipei on Ethical Considerations Regarding Health Databases and Biobanks.

Publication Ethics: Note this journal uses Turnitin software to detect plagiarism, instances of overlapping, and similar text in submitted manuscripts.

ORCID: As part of the journal’s commitment to supporting authors at every step of the publishing process, the journal requires the submitting authors to provide an ORCID iD when submitting a manuscript. This takes around 2 minutes to complete.

Double-blind review: Periodontology 4 journal uses double-blind review, which means the identities of the authors are concealed from the reviewers, and vice-versa. To facilitate this, please include the following separately:
Title page (with author details): This should include the full title, running title, authors’ names, affiliations, e-mail and ORCID, corresponding author and address, acknowledgments, Statement of clinical relevance. and any Declaration of Interest statement, and a complete address for the corresponding author including an e-mail address.
Blinded manuscript (no author details): The main body of the paper, figures, tables, and any acknowledgments should not include any identifying information, such as the authors’ names or affiliations.


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, they will be required to complete a license agreement on behalf of all authors of the paper. All articles will be published OPEN ACCESS, under the terms of a Creative Commons License.

Accepted Articles

Accepted Articles are published online a few days after final acceptance and appear in PDF format only. They are given a Digital Object Identifier (DOI), which allows them to be cited and tracked. After the final version article is published (the article of record), the DOI remains valid and can still be used to cite and access the article.

Submitting authors should therefore carefully check the names and affiliations of all authors provided on the cover page of the manuscript so it is accurate for indexing. 


The authors will receive an e-mail notification with a link and instructions for accessing the proofs. Page proofs should be carefully proofread for any copyediting or typesetting errors. Online guidelines are provided within the system. No special software is required, all common browsers are supported. Authors should also make sure that any renumbered tables, figures, or references match text citations, and that figure legends correspond with text citations and actual figures. Proofs must be returned within 48 hours of receipt of the email. Return of proofs via e-mail is possible in the event that the online system cannot be used or accessed. 


Access and sharing

When the article is published online: The author receives an email alert (if requested); link to the published article can be shared through social media; the author will have free access to the paper.
