QUINTESSENCE INTERNATIONALGUIDELINES FOR AUTHORS
Quintessence International publishes only clinically relevant scientificpapers, topic reviews, systematic reviews, case reports, and method
presentation articles in the field of dentistry. Original articles are published in all dentistry-related disciplines, relevant to dental and oral diseases and management. The journal aims to serve dentists in their practice by sharing and improving knowledge and experience.
Please read the instructions below for details on the submission ofmanuscripts and the journal’s requirements and standards.
Original articles are considered for publication on the condition thatthey have not been published, posted on a preprint repository site, or
submitted for publication elsewhere.
All articles should be clinically relevant to all dentistry-related disciplines
and addressed to the general dentist. The journal publishes several
types of peer-reviewed original articles:
1. Topic review and Systematic review articles. The review can be a
topic review or systematic review. It should cover a topic of interest for
the general practitioner and should address a clinical problem, diagnosis, or treatment. Reviews should offer a broad view of the field. The
review Abstract should have not more than 250 words and include:
Objectives, Data Sources, and Conclusion. The main text should be
divided into Introduction, Data Sources, Resources Selection, Review,
Discussion, and Conclusion. Search strategies must be described and theuse of evidence-based systematic approaches is expected. The Discussion and Conclusion should address the relevance to the general practitioner and should be supported with clinically relevant photographs.
Фю-$"$)'.$ )/$‫ݦ‬-/$' .юOriginal scientific articles must reach thehighest international standards in the field and should be relevant todental practice. The articles should describe significant and original
experimental observations and provide sufficient details so that theobservations can be critically evaluated and, if necessary, repeated. The
article Abstract should be no more than 250 words giving details of what
was done, using the following structure: Objectives: A clear statement of
the main goal of the study and any tested hypotheses. Method andMaterials: Describe the methods, study design, and data analysis. Results:
Main results of the study, including the outcome of any statistical analysis.
Conclusion: State the major conclusions of the study and their implications and relevance to the practice of dentistry.
The main text should include Introduction, Method and Materials,
Results, Discussion, and Conclusion sections. The Introduction shouldsummarize the background of the research objectives and shouldemphasize the relevance of the study to the practice of dentistry. The
Method and Materials section must contain sufficient detail such that, in
combination with the references cited, all clinical trials and experiments
reported can be fully reproduced. Manufacturers of materials should be
named, known methods should be referenced, and data analysis should
be described. The Results section should be presented in a logicalsequence in the text, tables, and illustrations. The Discussion section
should include association to previous studies, and implications of thefindings to the practice of dentistry should be included. The Conclusion
section should not summarize the findings. Instead, the conclusions
should relate to the aims of the study and the relevance to dental
practice. The conclusions should be supported by the data.
3. Case reports and short case presentation articles. Case reports
should have importance and significance to the practitioner; repetitionof well-known and extensively published conditions or methods will not
be accepted. Case reports should include: Abstract, Introduction, Case
Presentation, Discussion, and Conclusion/Recommendation when necessary. The Abstract should have not more than 250 words and summarize the case. The article should emphasize the new information provided and the relevance to general practitioners. Sufficient follow-up
period is required, and high-quality images should be included.

4. Short case presentations. These should be used for interesting but simpler cases, which the authors would like to share with the readers. The
abstract should include not more than 150 words and the main text is limited to 800 words. Only four illustrations and five references can be included.
5. Method presentation articles. The method presentation must offer
significant improvements in clinical practice (a novel technique, technological breakthrough, or practical approaches to clinical challenges). The
main text should be divided into an Introduction, Report, and Discussion.
All parts should be well-illustrated with clinical images, radiographs, diagrams, and, where appropriate, supporting tables and graphs.
Review/editing of manuscripts. Manuscripts will normally be reviewed
by the editor-in-chief, one associate editor, and at least two reviewers
with expertise in the article’s subject matter. The journal operates a conventional double-blind reviewing policy in which the reviewer’s name isalways concealed from the submitting author, and the authors’ names
are always concealed from the reviewers (although not from the editorin-chief or associate editors). External peer review is not mandatory inthe journal. After review by the editor-in-chief and/or an associate editor,
a decision is made whether to reject the work or to continue the review
process. Any works where the editor-in-chief is a contributor will be handled and decided upon by an associate editor. Any works where an associate editor is a contributor will be handled and decided up by an alternative associate editor and editor-in-chief. We attempt to begin thereview process as rapidly as possible, and a decision is reached as soon
as the reviewer’s comments are received, typically within 8 to 10 weeks.
The publisher reserves the right to edit manuscripts to ensure conciseness, clarity, and stylistic consistency, subject to the author’s final
approval.
Manuscripts are reviewed and selected in a blinded process byeditors and appropriate content experts. Therefore, it is important that
submitted manuscripts and illustrations do not contain information thatwill identify the paper’s origin (except for the title page, which will not besent to reviewers).
The editorial board’s decision is final and cannot be appealed.
Publication. Every effort is made to publish accepted articles expediently.
Authors should address all inquiries regarding this process to the Managing Editor, Ms Elizabeth Ducker (ducker@quintessence-publishing.com).
Advertising policy. All advertising appearing in Quintessence International must be approved by the editorial staff. The publication of an
advertisement is not to be construed as an endorsement of approval by
QI or its publisher.
Correction/retraction/expressions of concern policy. All expressions ofconcern, correction, or retraction should be directed to the Managing Editor (Ms Elizabeth Ducker, ducker@quintessence-publishing.com). Accepted manuscripts are part of the permanent scholarly record. They canbe withdrawn or retracted as per the version of record only. Retracted articles remain online with a retraction notice to ensure transparency. Copyright continues to apply to retracted articles.
Copyright assignment. The Mandatory Submission and CopyrightForm, available at https://www.quintessence-publishing.com/deu/en/journal/quintessence-international#downloads, must be signed by all
authors and uploaded to complete the submission process.
The submission of the manuscript by the authors means that theauthors agree to assign exclusive copyright to Quintessence Publishing
if and when the manuscript is accepted for publication. The work shallnot be published elsewhere in any language without the written consent
of the publisher. The articles published in this journal are protected bycopyright, which covers translation rights and the exclusive right to reproduce and distribute all of the articles published in the journal. No
material published in the journal may be stored physically or in electronic databases and the like, or reproduced photographically without
the prior written permission of the publisher.

Manuscript preparation
The Journal will follow as much as possible the recommendations of theInternational Committee of Medical Journal Editors in regard to preparation of manuscripts and authorship (Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly Work in Medical
Journals; www.icmje.org/recommendations).

In the submission letter, authors will be required to guarantee thatthe submission represents original work for first publication in the journal and that it is not being considered for publication elsewhere. The
work cannot have been already published other than in abstract form
(please acknowledge such), and permissions for the reproduction of any
copyright inclusions not owned by the author/s must have beenobtained. Submission to the journal explicitly implies that the author/s
own all rights to the work. The journal regards copyright infringement,
plagiarism, and other related publication malpractice very seriously.
Presentation. The presentation must clearly convey clinical reports,
research findings, or review objectives. Try to avoid using technical jargon, but clearly explain where its use is inevitable. Titles, abstracts, andmain text should be written in language readily intelligible to any dentist. The structure should reflect the manuscript type.
Title page. This should include the title of the article and the names,
academic degrees, and professional affiliations for all authors. An email
address and postal address must also be provided for the corresponding
author. If the paper was presented before an organized group, the nameof the organization, location, and date should be included. Please selecttitles that reflect the core aspects of the work, are easy to read, anddescribe the study design if relevant (ie, randomized controlled trial,
case-control study, cohort study, etc). Concise titles are preferred.
Abstract/keywords. Please include a maximum 250-word structured
abstract (with headings Objectives, Method and Materials, Results, andConclusion, depending on manuscript type) and up to 6 key words inalphabetical order.
' .)‫"ݦ‬0- .ю All figures and tables should be numbered and citedin the text in order of appearance. Figure legends should begin with abrief title for the whole figure and continue with a short description ofeach panel and the symbols used. Legends should be grouped at the endof the text. Figures and tables can be grouped at the end of the manuscript or uploaded individually.
■ Clinical images should be at least 300 dpi at 9 cm wide.
■ Images grouped together (eg, 1a to 1c) must be saved as individual
files (eg, 1a, 1b, 1c).
■ Line art (eg, graphs, charts, line drawings) should be provided as
editable vector art (eg, Illustrator or EPS files).
■ Images containing type should either be saved as a layered file orprovided along with a second file with type removed.
Note that article acceptance is pending receipt of acceptable originalart.
Statistical methods. Indicate the statistical methods used, if applicable,
in a separate section. Describe all details of the statistical analyses. Useof one-tailed analyses requires clear justification. Indicate the alpha(cut-off) value set for statistical significance. Report all P values as “.XX”
and do not use “not significant” or its abbreviation. For P values between.001 and .10, report the value within three decimal places. For P values
greater than .10, please report the value with two decimal places. For
P values less than .001, report as “ P < .001,” except for genomewide
association studies. For group differences, show the appropriate effectmeasure (eg, relative risk, absolute risk, difference of means).
Abbreviations/acronyms. Abbreviations should be kept to a minimum,
particularly those that are not standard. Terms and names referred to as
abbreviations or acronyms should be written out when first used withthe abbreviation in parenthesis. Standard units of measurement neednot be spelled out.
Tooth numbering. The complete names of individual teeth must be
given in the text. Only in tables and figures, individual teeth can be identified using the FDI 2-digit system if full tooth names are too unwieldy.
Trade names. Generic terms are to be used whenever possible, but trade
names and manufacturer should be included parenthetically at firstmention.
