Submission of manuscripts
Manuscripts for publication and correspondence relating to them should be sent to:
The Virtual Journal of Orthodontics publishes articles about original researches and clinical observations; review articles about Orthodontics and related subjects; editorials; news, comments, and service announcements.
Manuscripts are accepted for publication with the stipulation that they are original, written in English, Italian or Spanish, and have not been published or submitted for publication elsewhere.
Manuscripts will be reviewed by the VJO Reading Committee and are subject to editorial revision.
Statements and opinions expressed in the articles and communications herein are those of the author(s) and not necessarily those of the editor, and the editor disclaims any responsibility or liability for such material. The editor does not guarantee, warrant, or endorse any product or service advertised in this publication; neither does he guarantee any claim made by the manufacturer of such product or service. Each reader must determine whether to act on the information contained in the publication, and neither the Journal nor its sponsoring organizations shall be liable for any injury due to the publication of erroneous information.
A cover letter signed by all the authors should identify the person (with his/her street address, telephone/fax numbers and e-mail address) responsible for negotiations concerning the paper. The letter should clearly state that the final manuscript has been seen and approved by all the authors and that they have taken due care to ensure the integrity of the work.
Authors are required to grant Virtual Journal of Orthodontics a formal written Consent to Publish and an exclusive licence in respect of their contributions to the Journal.
This helps the Virtual Journal of Orthodontics to protect the published material against unauthorized copying and other misuse and to properly authorize dissemination of the work by means of Internet, electronic files, translations, and secondary information sources including converting the text into machine readable form and storing it in electronic databases. Furthermore, it ensures that requests from third parties to publish all or part of the material we publish can be efficiently dealt with.
Even though the Copyright Licence is exclusive, the Virtual Journal of Orthodontics will agree to any reasonable request for permission to republish contents if accompanied by a suitable acknowledgment of first publication by the Virtual Journal of Orthodontics. Authors will be consulted, when possible, regarding republication of their material.
The Authors are hereby requested to complete and return the enclosed form via fax promptly so that the manuscript may be readied for publication.
Conflict of interest
Authors will be asked to sign a conflict of interest declaration, in which they report any commercial association that might pose a conflict of interest, such as ownership, stock holdings, equity interests and consultant activities, or patent-licensing situations.
Such information is confidential and will not be disclosed to editorial consultants (VJO staff) or to the scientific committee. It does not play a part in the decision of the quality or timeliness of the manuscript.
If the manuscript is accepted, the disclosed information will be published with the article. The usual and customary listing of sources of support and institutional affiliations on the title page is proper and does not imply a conflict of interest.
- send via e-mail text and images to: ti.oj1488300958v@rot1488300958ide1488300958
The text should be in English, Italian, or Spanish and without formatting characters and saved as only text (.txt), when possible compressed in zip format.
Images should be in GIF format for drawings or charts and JPEG for photos.
- send all text and images via traditional mail on a computer readable media (e.g. floppy disks or CD rom). Disks should be labeled with the computer type (IBM or Macintosh), word-processing program, title of paper, and first author’s name.
- send the typed manuscript via traditional mail, submitting the original and two copies, typewritten with double spacing on one side of white or recycled paper (each page containing no more than 350 words).
In any case the author should retain another copy for personal reference. (See paragraph on Illustrations for submission of these.)
The word processor’s default typeface and type size should be used. Text formatting capabilities should not be used.
- The title page should include the title of the article, full name(s) of the author(s), academic degrees, and institutional affiliations and positions; in the interest of anonymity, the information pertaining to the author should appear only on the original manuscript. The corresponding author’s address, business and home telephone numbers, fax numbers, and e-mail address should be given.
- Provide an abstract of 225 words or less. Briefly state the problem or purpose, the major observations, the methods, and the principal conclusions.
- Provide an introduction stating the study’s objective and omit extensive review of the literature, which is normally found in a thesis.
- The materials or subjects and methods/case histories section describe the experimental design procedures and subjects used. Give the details only if the methods are original or essential for understanding; otherwise, give references. Never mix discussion with this section or with the Results section.
- Present the results with a minimum of discussion. Use tables, charts, and photographs to clarify the findings. Finally, check the statistics, and quote statistical jargon only if you are personally familiar with it.
- Point out the significance of the data and the limitations in the discussion section. Speculation should be clearly identified as such. Do not repeat the introduction in this section. Keep this section to approximately one third of the total manuscript. It should not exceed one half of the complete article’s length.
- All measurements should be expressed in metric units, or metric equivalents may appear in parentheses after the original measurement. To avoid confusion caused by varying tooth-numbering systems, provide the full name of the tooth and its upper or lower quadrant position.
- Be sure to include a clearly labeled conclusion.
- References (1): References should be numbered consecutively in the order in which they are first mentioned in the text. Identify references in text, tables, and legends by Arabic numerals in parentheses. References cited only in tables or figure legends should be numbered in accordance with the sequence established by the first identification in the text of the particular table or figure.
Use the style of the examples below, which are based on the formats used by the NLM in Index Medicus. The titles of journals should be abbreviated according to the style used in Index Medicus. Consult the List of Journals Indexed in Index Medicus, published annually as a separate publication by the library and as a list in the January issue of Index Medicus. The list can also be obtained through the library’s web site.
References: how to cite
Avoid using abstracts as references. References to papers accepted but not yet published should be designated as “in press” or “forthcoming”; authors should obtain written permission to cite such papers as well as verification that they have been accepted for publication. Information from manuscripts submitted but not accepted should be cited in the text as “unpublished observations” with written permission from the source.
Avoid citing a “personal communication” unless it provides essential information not available from a public source, in which case the name of the person and date of communication should be cited in parentheses in the text. For scientific articles, authors should obtain written permission and confirmation of accuracy from the source of a personal communication.
The references must be verified by the author(s) against the original documents.
The Uniform Requirements style (the Vancouver style) is based largely on an ANSI standard style adapted by the NLM for its databases. Notes have been added where Vancouver style differs from the style now used by NLM.
