Section Scope Statements

The Oral and Maxillofacial Surgery Section aims to publish an extensive range of original articles that advances patient care through enhanced understanding of diagnosis, surgical and adjunctive treatment of diseases, and injuries and defects involving both the functional and esthetic aspects of the hard and soft tissues of the oral and maxillofacial regions. The section also seeks research regarding both the basic science of and management of persons with oral and maxillofacial conditions. Articles presenting ethical, original, well-documented, and reproducible research are given preference.

The Oral Medicine Section aims to publish a broad range of original articles that help clinicians understand more thoroughly the pathobiology, etiology, diagnosis, prevention, and management of oral conditions related to underlying medical conditions, including diseases of the head, neck, and oral mucosal structures, orofacial pain conditions, salivary gland disorders, and taste disorders. The section also seeks research regarding the dental management of persons with medical problems and/or complicated medical conditions. The published findings must contribute substantively to the body of oral medicine literature and should lead to improved clinical decision-making and enhanced care of medically-related disorders or conditions affecting the oral and maxillofacial region. Articles presenting original, well-documented, and reproducible research are preferred.

The Oral and Maxillofacial Pathology Section encourages the submission of original articles of high scientific quality that investigate the pathogenesis, diagnosis, and management of diseases affecting the oral and maxillofacial region. Submitted manuscripts may summarize findings from clinical, translational, or basic research in the broad field of oral and maxillofacial pathology but must contribute substantively to the body of knowledge in this field and should be of obvious clinical and/or diagnostic significance to the practicing oral and maxillofacial pathologist. Areas of focus may include the investigation of disease pathogenesis, the diagnosis of disease using microscopic, clinical, radiographic, biochemical, molecular, or other methods as well as the natural history and management of patients with various conditions of the head, neck, and oral mucosal structures. Diagnostic accuracy studies should conform to the principles of the STARD document http://www.stard-statement.org. Articles presenting novel and reproducible research that introduce new knowledge and observations are especially encouraged. This section also welcomes the submission of topical review papers on relevant subjects.

The Oral and Maxillofacial Radiology Section publishes original peer-reviewed contributions to the advancement of diagnostic clinical oral and maxillofacial radiology and related imaging sciences. The section considers original clinical and experimental research papers, technological developments, extensive systematic reviews of the literature, comprehensive pictorial reviews, special reports, and invited papers on subjects that will appeal to clinicians involved in the diagnostic imaging of hard and soft tissue maxillofacial pathology, selection criteria, computer-assisted diagnosis, craniofacial analysis, image-guided surgical navigation, image processing, dosimetry, radiation physics, biology, and safety.
The section also seeks extensive case series representing various expressions of particular conditions, descriptions of innovative imaging technique applications to these series, and description of novel imaging features to assist imaging specialists develop clinical protocols and interpretive knowledge based on multiple observations. Only papers contributing substantively to the body of knowledge in oral and maxillofacial imaging and performed with scientific rigor will be considered. These papers should assist clinicians in developing evidence-based practice and provide improved clinical decision-making regarding the performance of specific techniques and interpretation of resulting images affecting the oral and maxillofacial region. Diagnostic accuracy studies should conform to the principles of the STARD document http://www.stard-statement.org).

Types of Papers

1. Original Research Article. Reports of original research (preclinical, clinical, or translational) that are well-documented, novel, and significant. Original research manuscripts will be organized into six parts: (1) Abstract; (2) Introduction; (3) Materials and Methods; (4) Results; (5) Discussion; (6) References.

2. Review article. Manuscripts that review the current status of a given topic, diagnosis, or treatment. These manuscripts should not be an exhaustive review of the literature but rather should be a review of contemporary thought with respect to the topic. Systematic reviews and meta-analyses manuscripts should follow PRISMA (http://www.prisma-statement.org) and the Institute of Medicines' guidelines (http://www.iom.edu/Reports/2011/Finding-What-Works-in-Health-Care-Standards-for-Systematic-Reviews/Standards.aspx).

3. Clinicopathologic Conference (CPC). Manuscripts that document interesting, challenging, or unusual cases that present unexpected or interesting diagnostic challenges. The presentation should simulate clinical work-up, including the formulation of a detailed and well thought out differential diagnosis. The complete diagnostic evaluation, management, and follow-up must be included. CPC articles must be organized into six parts: (1) Title: Provide a descriptive clinical title that does not reveal the final diagnosis. (2) Clinical presentation: Describe the clinical and imaging characteristics of the lesion. Use clinical photographs and radiographs as appropriate. (3) Differential diagnosis: List and discuss lesions to be considered as reasonable diagnostic possibilities. The authors are reminded that the most important part of the CPC manuscript is the clinical differential diagnosis, where the authors guide the readership through their own diagnostic thought process. This will require the formulation of a list of the most probable diagnostic possibilities (ideally at least 5-6 entities) based on the clinical presentation, medical history, and/or radiographic studies. (4) Diagnosis: Histopathologic findings illustrated with appropriate photomicrographs. (5) Management: Describe the treatment of the patient and response to treatment. (6) Discussion: Concentrate on the most interesting aspect(s) of the case. No abstract is needed for CPC manuscripts.

4. Medical Management and Pharmacology Update (MMPU). This section is intended to provide concise, current reviews of medical problems and how they relate to dentistry. Manuscripts should include a good review of the clinical aspects of the disease, stressing the impact of the disease on the dental management and dental treatment of the patient. Emphasis should be placed on new developments, new research, or new approaches to therapy or management. Manuscripts should not be an exhaustive review of the literature but rather a review of contemporary thought with respect to the topic. Likewise, the bibliography need not be all inclusive but rather should include only seminal, contemporary references deemed by the author to be most pertinent. The desired format for manuscripts submitted for the MMPU section includes: (1) abstract; (2) topic introduction/overview; (3) epidemiology/demographics; (4) etiology and pathogenesis; (5) clinical presentation/physical findings; (6) diagnosis (laboratory tests, diagnostic imaging, etc.); (7) medical management and treatment; (8) complications; (9) prognosis; oral manifestations/dental implications and significance; and (10) dental management (of patients with the disease). Manuscripts should not exceed 12 pages in 12-point, double-spaced Times New Roman (tables and figures count toward the 12-page limit).

5. Pharmacology Update is a component of the MMPU section that offers the reader the opportunity to obtain concise information regarding drugs used in the practice of medicine, clinical dentistry, and dental specialties. Manuscripts should present clearly and concisely the background information regarding the disease or condition that is managed, the indications, rationale for and approved uses of the specific drugs or class of drugs, the advantages and benefits of the drug or drug class over previous drugs, mechanism of action, criteria for selection, usual dosage, pharmacokinetics, adverse effects, drug interactions, and oral health and dental management considerations. Emphasis should be placed on new developments, effectiveness in clinical trials, therapeutic outcomes, and safety. Manuscripts should reflect contemporary thought with respect to the topic. Use of figures to illustrate the mechanism of action and tables to present therapeutic outcomes, drug interactions, and adverse effects are encouraged. Manuscripts should utilize the MMPU categories for formatting the paper. Text should not exceed 3,000 words. Font should be 12-point, double-spaced Times New Roman. A maximum of 50 references is recommended.

6. Case Reports. These types of publications often add little to the scientific knowledge base. However, excellent case reports may be published as online only papers if they meet certain criteria, such as: (1) rare or unusual lesions/conditions that need documentation, (2) well-documented cases showing unusual or "atypical" clinical or microscopic features or behavior, or (3) cases showing good long-term follow-up information, particularly in areas in which good statistics on results of treatment are needed. A case report should either present unique features of the condition or lesion, novel treatment regimens, or provide the basis for a new plausible medical theory about the pathogenesis of a particular disease or condition so clinicians can provide better care regarding patients with chronic and painful conditions relevant to medical disorders and/or medical therapy.

Ethics in publishing

For information on Ethics in publishing and Ethical guidelines for journal publication see http://www.elsevier.com/publishingethics and http://www.elsevier.com/journal-authors/ethics.

Conflict of interest

All authors must disclose any financial and personal relationships with other people or organizations that could inappropriately influence (bias) their work. Examples of potential conflicts of interest include employment, consultancies, stock ownership, honoraria, paid expert testimony, patent applications/registrations, and grants or other funding. If there are no conflicts of interest then please state this: 'Conflicts of interest: none'. See also http://www.elsevier.com/conflictsofinterest. Further information and an example of a Conflict of Interest form can be found at: http://help.elsevier.com/app/answers/detail/a_id/286/p/7923.

Submission declaration

Submission of an article implies that the work described has not been published previously (except in the form of an abstract or as part of a published lecture or academic thesis or as an electronic preprint, see http://www.elsevier.com/sharingpolicy), that it is not under consideration for publication elsewhere, that its publication is approved by all authors and tacitly or explicitly by the responsible authorities where the work was carried out, and that, if accepted, it will not be published elsewhere including electronically in the same form, in English or in any other language, without the written consent of the copyright-holder.

If there is any overlap between the submission and any other material, published or submitted, detail the nature of and reason for the overlap for the editors' assessment. Although poster presentations and abstracts are not considered duplicate publication, they should be stated on the title page. Further information about Elsevier's standards for publication ethics is available at http://www.elsevier.com/wps/find/intro.cws_home/ethical_guidelines.

Authorship

All authors should have made substantial contributions to all of the following: (1) the conception and design of the study, or acquisition of data, or analysis and interpretation of data, (2) drafting the article or revising it critically for important intellectual content, (3) final approval of the version to be submitted.

All authors must have seen and approved the submission of the manuscript and be willing to take responsibility for the entire manuscript. All persons listed as authors must meet the criteria for authorship according to the "Uniform Requirements for Manuscripts Submitted to Biomedical Journals: Writing and Editing for Biomedical Publication" available at www.icmje.org. All persons who are identified as authors must have made substantial contribution to the manuscript through significantly contributing to the conception, design, analysis or interpretation of data; drafting or significantly revising the manuscript; and providing final approval of the manuscript throughout all its iterations. All three of these conditions must be met by each author. No additional authors can be added after submission unless editors receive agreement from all authors and detailed information is supplied as to why the author list should be amended. Persons who contribute to the effort in supporting roles should not be included as authors; they should be acknowledged at the end of the paper (see Acknowledgments below).

Changes to authorship

This policy concerns the addition, deletion, or rearrangement of author names in the authorship of accepted manuscripts:
Before the accepted manuscript is published in an online issue: Requests to add or remove an author, or to rearrange the author names, must be sent to the Journal Manager from the corresponding author of the accepted manuscript and must include: (a) the reason the name should be added or removed, or the author names rearranged and (b) written confirmation (e-mail, fax, letter) from all authors that they agree with the addition, removal or rearrangement. In the case of addition or removal of authors, this includes confirmation from the author being added or removed. Requests that are not sent by the corresponding author will be forwarded by the Journal Manager to the corresponding author, who must follow the procedure as described above. Note that: (1) Journal Managers will inform the Journal Editors of any such requests and (2) publication of the accepted manuscript in an online issue is suspended until authorship has been agreed.
After the accepted manuscript is published in an online issue: Any requests to add, delete, or rearrange author names in an article published in an online issue will follow the same policies as noted above and result in a corrigendum.

Registration of clinical trials

Registration in a public trials registry is a condition for publication of clinical trials in this journal in accordance with International Committee of Medical Journal Editors (ICMJE, http://www.icmje.org) recommendations. Trials must register at or before the onset of patient enrolment. The clinical trial registration number should be included at the end of the abstract of the article. A clinical trial is defined as any research study that prospectively assigns human participants or groups of humans to one or more health-related interventions to evaluate the effects of health outcomes. Health-related interventions include any intervention used to modify a biomedical or health-related outcome (for example drugs, surgical procedures, devices, behavioural treatments, dietary interventions, and process-of-care changes). Health outcomes include any biomedical or health-related measures obtained in patients or participants, including pharmacokinetic measures and adverse events. Purely observational studies (those in which the assignment of the medical intervention is not at the discretion of the investigator) will not require registration.

Clinical trial results

In line with the position of the International Committee of Medical Journal Editors, the journal will not consider results posted in the same clinical trials registry in which primary registration resides to be prior publication if the results posted are presented in the form of a brief structured (less than 500 words) abstract or table. However, divulging results in other circumstances (e.g., investors' meetings) is discouraged and may jeopardise consideration of the manuscript. Authors should fully disclose all posting in registries of results of the same or closely related work.

Article transfer service

This journal is part of our Article Transfer Service. This means that if the Editor feels your article is more suitable in one of our other participating journals, then you may be asked to consider transferring the article to one of those. If you agree, your article will be transferred automatically on your behalf with no need to reformat. Please note that your article will be reviewed again by the new journal. More information about this can be found here: http://www.elsevier.com/authors/article-transfer-service.

Copyright

Upon acceptance of an article, authors will be asked to complete a 'Journal Publishing Agreement' (for more information on this and copyright, see http://www.elsevier.com/copyright). An e-mail will be sent to the corresponding author confirming receipt of the manuscript together with a 'Journal Publishing Agreement' form or a link to the online version of this agreement.

Green open access

Authors can share their research in a variety of different ways and Elsevier has a number of green open access options available. We recommend authors see our green open access page for further information (http://elsevier.com/greenopenaccess). Authors can also self-archive their manuscripts immediately and enable public access from their institution's repository after an embargo period. This is the version that has been accepted for publication and which typically includes author-incorporated changes suggested during submission, peer review and in editor-author communications. Embargo period: For subscription articles, an appropriate amount of time is needed for journals to deliver value to subscribing customers before an article becomes freely available to the public. This is the embargo period and begins from the publication date of the issue your article appears in.

This journal has an embargo period of 12 months.

Language (usage and editing services)
Please write your text in standard, grammatical English (American or British usage is accepted, but not a mixture of these). Authors who feel their English language manuscript may require editing to eliminate possible grammatical or spelling errors and to conform to correct scientific English may wish to use the English Language Editing service available from Elsevier's WebShop ( http://webshop.elsevier.com/languageediting/) or visit our customer support site ( http://support.elsevier.com) for more information. Such assistance does not guarantee acceptance but may enhance the review, improve the chance of acceptance, and reduce the time until publication if the article is accepted.

Informed consent and patient details

Studies on patients or volunteers require ethics committee approval and informed consent, which should be documented in the paper. Appropriate consents, permissions and releases must be obtained where an author wishes to include case details or other personal information or images of patients and any other individuals in an Elsevier publication. Written consents must be retained by the author and copies of the consents or evidence that such consents have been obtained must be provided to Elsevier on request. For more information, please review the Elsevier Policy on the Use of Images or Personal Information of Patients or other Individuals, http://www.elsevier.com/patient-consent-policy. Unless you have written permission from the patient (or, where applicable, the next of kin), the personal details of any patient included in any part of the article and in any supplementary materials (including all illustrations and videos) must be removed before submission.

Submission

Our online submission system guides you stepwise through the process of entering your article details and uploading your files. The system converts your article files to a single PDF file used in the peer-review process. Editable files (e.g., Word, LaTeX) are required to typeset your article for final publication. All correspondence, including notification of the Editor's decision and requests for revision, is sent by e-mail.

Submit your article
Please submit your article via http://ees.elsevier.com/tripleo.

Use of word processing software

It is important that the file be saved in the native format of the word processor used. The text should be in single-column format. Keep the layout of the text as simple as possible. Most formatting codes will be removed and replaced on processing the article. In particular, do not use the word processor's options to justify text or to hyphenate words. However, do use bold face, italics, subscripts, superscripts etc. When preparing tables, if you are using a table grid, use only one grid for each individual table and not a grid for each row. If no grid is used, use tabs, not spaces, to align columns. The electronic text should be prepared in a way very similar to that of conventional manuscripts (see also the Guide to Publishing with Elsevier: http://www.elsevier.com/guidepublication). Note that source files of figures, tables and text graphics will be required whether or not you embed your figures in the text. See also the section on Electronic artwork.
To avoid unnecessary errors you are strongly advised to use the 'spell-check' and 'grammar-check' functions of your word processor.

LaTeX

You are recommended to use the Elsevier article class elsarticle.cls (http://www.ctan.org/tex-archive/macros/latex/contrib/elsarticle) to prepare your manuscript and BibTeX (http://www.bibtex.org) to generate your bibliography.
For detailed submission instructions, templates and other information on LaTeX, see http://www.elsevier.com/latex.

Article structure

Essential Title Page Information

The title page of the manuscript should include the title of the article, the full name of the author(s), academic degrees, positions, and institutional affiliations. The corresponding author's address, business and home telephone numbers, fax number, and e-mail address should be given. Disclosures must appear on the title page (see Disclosures).

Title. Concise and informative. Titles are often used in information-retrieval systems. Avoid abbreviations and formulae where possible.
Author names, academic degrees, positions, and institutional affiliations. Where the family name may be ambiguous (e.g., a double name), please indicate this clearly. Present the authors' affiliation addresses (where the actual work was done) below the names. Indicate all affiliations with a lower-case superscript letter immediately after the author's name and in front of the appropriate address. Provide the full postal address of each affiliation, including the country name and, if available, the e-mail address of each author.
Corresponding author. Clearly indicate who will handle correspondence at all stages of refereeing and publication, also post-publication. Ensure that phone numbers (with country and area code) are provided in addition to the e-mail address and the complete postal address. Contact details must be kept up to date by the corresponding author.
Present/permanent address. If an author has moved since the work described in the article was done, or was visiting at the time, a 'Present address' (or 'Permanent address') may be indicated as a footnote to that author's name. The address at which the author actually did the work must be retained as the main, affiliation address. Superscript Arabic numerals are used for such footnotes.
Disclosures must appear on the title page (see “Conflict of Interest” above).

Include on the title page a word count for the abstract (if relevant to article type), a complete manuscript word count (to include body text and figure legends), number of references, number of figures/tables, and number of supplementary elements, if any.

Statement of Clinical Relevance

For Original research, Review, and MMPU manuscripts, please provide a brief statement of no more than 40 words that succinctly summarizes the clinical relevance of the findings described in your manuscript.
For example:

"The risk of postoperative bleeding complications in patients in whom anticoagulation is continued for dental surgery is exceedingly small and is outweighed by the small risk of serious and sometimes fatal embolic events when anticoagulation is interrupted for dental surgery." (Wahl et al. 119(2) doi:10.1016/j.oooo.2014.10.011)

Abstract

A structured abstract, limited to 200 words, must be used for data-based research articles. The structured abstract is to contain the following major headings: Objective(s); Study Design; Results; and Conclusion(s). The Objective(s) reflects the purpose of the study, that is, the hypothesis that is being tested. The Study Design should include the setting for the study, the subjects (number and type), the treatment or intervention, and the type of statistical analysis. The Results include the outcome of the study and statistical significance if appropriate. The Conclusion(s) states the significance of the results. For nondata-based submissions, the abstract should be an unstructured summary of less than 150 words. No abstract is needed for submissions to the CPC section.

Subdivision - unnumbered sections

Divide your article into the following clearly defined sections. Each subsection is given a brief heading. Each heading should appear on its own separate line. Subsections should be used as much as possible when cross-referencing text: refer to the subsection by heading as opposed to simply 'the text'.

Introduction

State the problem being investigated, summarize the existing knowledge to place the problem in context, and describe the hypothesis and general experimental design. Avoid a detailed literature survey or a summary of the results.

Materials and Methods

As relevant, the Materials and Methods section should describe in adequate detail the experimental subjects, their important characteristics, and the methods, apparatus, and procedures used so that other researchers can reproduce the experiment. When the manuscript submitted reports on research in which humans are involved as experimental subjects directly or indirectly, the Materials and Methods section must indicate that the protocol was reviewed by the appropriate institutional review board (IRB), is in compliance with the Helsinki Declaration, and that each subject in the project signed a detailed informed consent form. Authors should verify compliance with the Health Insurance Portability and Accountability Act of 1996 (HIPAA) before submission. Provide sufficient detail to allow the work to be reproduced. Methods already published should be indicated by a reference; only relevant modifications should be described.

Animals. Please indicate that protocols were reviewed by the appropriate institutional committee with respect to the humane care and treatment of animals used in the study.

Results

Results should be clear and concise and presented in a logical sequence. Tables and illustrations may be helpful in clarifying the findings and can reduce the length of the manuscript.

Discussion

The Discussion states the significance of the results and limitations of the study. Authors should discuss their findings in the framework of previously published research. They should explain why their results support or contradict existing knowledge. If appropriate, the authors may suggest further research to follow up on their findings.

Units

Follow internationally accepted rules and conventions: use the international system of units (SI). If other units are mentioned, please give their equivalent in SI.

Dental Nomenclature. Because of competing dental nomenclature systems, confusion can be eliminated by identifying teeth by their name, rather than a number or letter. Be consistent throughout the manuscript.

In tables, use the Universal Numbering System to identify the teeth. For example, the maxillary right permanent lateral incisor is designated tooth 7. The mandibular right deciduous second molar is designated tooth T. Identify the numbers/letters in the footnote to the table like any other abbreviations.

Math formulae

Present simple formulae in the line of normal text where possible and use the solidus (/) instead of a horizontal line for small fractional terms, e.g., X/Y. In principle, variables are to be presented in italics. Powers of e are often more conveniently denoted by exp. Number consecutively any equations that have to be displayed separately from the text (if referred to explicitly in the text).

Footnotes

Footnotes should be used sparingly. Number them consecutively throughout the article. Many word processors can build footnotes into the text, and this feature may be used. Otherwise, please indicate the position of footnotes in the text and list the footnotes themselves separately at the end of the article. Do not include footnotes in the Reference list.

Acknowledgments

The names of persons who have contributed substantially to a manuscript but who do not fulfill the criteria for authorship, along with their conflicts of interest, funding sources, and industry relations, if relevant, are to be listed in the Acknowledgment section. This section should include individuals who provided any writing, editorial, statistical assistance, etc. Collate acknowledgments in a separate section at the end of the article before the references and do not, therefore, include them on the title page, as a footnote to the title or otherwise. Do not include statements of the authors' funding, conflicts, or other disclosures in the Acknowledgments; these must appear on the title page.

References

Citation in text
References should be complete and reflect the current state of knowledge on the topic. Make sure all references have been verified and are cited consecutively in the text (not including tables) by superscript numbers. The reference list should be typed double-spaced on a separate page of the manuscript file and numbered in the same order as the reference citations appear in the text.

Please ensure that every reference cited in the text is also present in the reference list (and vice versa). Any references cited in the abstract must be given in full. Unpublished results and personal communications are not to be cited in the reference list but are to be cited in parentheses at the appropriate place in the text. Citation of a reference as 'in press' implies that the item has been accepted for publication, and publication information must be updated if the manuscript is accepted.

Reference links
Increased discoverability of research and high quality peer review are ensured by online links to the sources cited. In order to allow us to create links to abstracting and indexing services, such as Scopus, CrossRef and PubMed, please ensure that data provided in the references are correct. Please note that incorrect surnames, journal/book titles, publication year and pagination may prevent link creation. When copying references, please be careful as they may already contain errors. Use of the DOI is encouraged.

Web references
As a minimum, the full URL should be given and the date when the reference was last accessed. Any further information, if known (DOI, author names, dates, reference to a source publication, etc.), should also be given. Web references can be listed separately (e.g., after the reference list) under a different heading if desired, or can be included in the reference list.

Reference style
If accepted, the reference style used by the journal will be applied to the accepted article by Elsevier at the proof stage. Make sure the information in each reference is complete and correct. To see the format used by the journal, refer to a recent issue.

Journal abbreviation source
Journal names should be abbreviated according to the List of Title Word Abbreviations: http://www.issn.org/services/online-services/access-to-the-ltwa/.

Artwork

Electronic artwork

Illustrations should be numbered with Arabic numerals in the order of appearance in the text and accompanied by suitable legends (see Figure Captions).

A reasonable number of halftone illustrations or line drawings will be reproduced at no cost to the author. At the editors' discretion, color illustrations may be published in grayscale with the color image available in the online edition of the Journal; elaborate tables and extra illustrations, if accepted, may also appear as supplementary material in the online edition only. Typewritten or freehand lettering on illustrations is not acceptable. All lettering must be done professionally, and letters should be in proportion to the drawings or photographs on which they appear.

Figures must be submitted in electronic figure file format. For best reproduction, images should be submitted in .tif format. Figures in .jpg format may be acceptable if they meet minimum resolution guidelines. Images embedded in programs such as PowerPoint or Word will not be accepted. Photographic images must be submitted at 300 ppi (pixels per inch) with the following dimensions: Full page 5" wide (1,500 pixels wide) or half page 3" wide (900 pixels wide). Screen capture resolutions (typically 72 ppi) will not provide adequate reproduction quality. Line-art images (charts, graphs) must be submitted at 1200 ppi with the following dimensions: Full page 5" wide (6000 pixels wide) or half page 3" wide (3600 pixels wide).

Avoid background gridlines and other formatting that do not convey information (e.g., superfluous use of 3-dimensional formatting, background shadings). All images should be cropped to show only the area of interest and the anatomy necessary to establish a regional frame of reference. Although multipart figures are not preferred, if they are used, label multipart figures with capital letters (e.g., A, B, C, etc); do not exceed nine parts to one figure. If images are to be combined in one figure, they should be the same height and magnification to facilitate reproduction.

For advice on image enhancement and annotation refer to Corl FM, et al. A five-step approach to digital image manipulation for the radiologist. RadioGraphics 2002;22:981-992.

Color artwork
If, together with your accepted article, you submit usable color figures then Elsevier will ensure, at no additional charge, that these figures will appear in color on the Web (e.g., ScienceDirect and other sites) in addition to color reproduction in print. For further information on the preparation of electronic artwork, please see http://www.elsevier.com/artworkinstructions. Please note: Because of technical complications that can arise by converting color figures to 'gray scale' (for the printed version should you not opt for color in print), please submit in addition usable black and white versions of all the color illustrations.

Illustration services

Elsevier's WebShop (http://webshop.elsevier.com/illustrationservices) offers Illustration Services to authors preparing to submit a manuscript but concerned about the quality of the images accompanying their article. Elsevier's expert illustrators can produce scientific, technical and medical-style images, as well as a full range of charts, tables and graphs. Image 'polishing' is also available, where our illustrators take your image(s) and improve them to a professional standard. Please visit the website to find out more.

Figure captions

Each illustration must be accompanied by a legend. These should be typed double-spaced on a separate page. Keep text in the illustrations themselves to a minimum but explain all symbols and abbreviations used. If an illustration has been taken from published or copyrighted material, the legend must give full credit to the original source and accompanied by signed, written permission from the copyright holder (see Permissions below).

Artwork: General points

• Make sure you use uniform lettering and sizing of your original artwork.
• Embed the used fonts if the application provides that option.
• Aim to use the following fonts in your illustrations: Arial, Courier, Times New Roman, Symbol, or fonts that look similar.
• Number the illustrations according to their sequence in the text.
• Use a logical naming convention for your artwork files.
• Provide captions to illustrations to appear as a separate page in the manuscript file.
• Size the illustrations close to the desired dimensions of the printed version.
• Submit each illustration as a separate file.
A detailed guide on electronic artwork is available on our website: http://www.elsevier.com/artworkinstructions
You are urged to visit this site; some excerpts from the detailed information are given here.
Formats
Please 'Save as' or convert the images to one of the following formats (note the resolution requirements for line drawings, halftones, and line/halftone combinations given below):
EPS (or PDF): Vector drawings, embed all used fonts.
TIFF (or JPEG): Color or grayscale photographs (halftones), keep to a minimum of 300 ppi.
TIFF (or JPEG): Bitmapped (pure black & white pixels) line drawings, keep to a minimum of 1200 ppi.
Please do not:
• Supply files that are optimized for screen use (e.g., GIF, BMP, PICT, WPG); these typically have a low number of pixels and limited set of colors;
• Supply files that are too low in resolution;
• Submit graphics that are disproportionately large for the content.

Tables

Number tables consecutively using Roman numerals in accordance with their appearance in the text.
Each table should be submitted as a separate file. Tables should be self-explanatory and should supplement, not duplicate, the text. All table reference citations should be repeats of numbers assigned within the text, not initial citations. A concise title should be supplied for each table. All columns should carry concise headings describing the data therein. Type all footnotes immediately below the table and define abbreviations (see also Dental Nomenclature above). If a table or any data therein have been previously published, a footnote to the table must give full credit to the original source and accompanied by signed, written permission from the copyright holder (see Permissions below).

Supplementary Data

To save print pages and/or shorten an article to a readable length while allowing for detailed information to be available to interested readers, authors are encouraged to provide information that is essential for the discussion of the results of the submission in the submission itself and utilize supporting information to describe experimental details and nonessential but useful information as Supplementary Material. If the manuscript is accepted for print publication, a reference to the online material will appear in the print version.

Supplementary files offer the author additional possibilities to publish supporting applications, high-resolution images, background datasets, sound clips and more. Supplementary files supplied will be published online alongside the electronic version of your article in Elsevier Web products, including ScienceDirect: http://www.sciencedirect.com. In order to ensure that your submitted material is directly usable, please provide the data in one of our recommended file formats. Authors should submit the material in electronic format together with the article and supply a concise and descriptive caption for each file. For more detailed instructions please visit our artwork instruction pages at http://www.elsevier.com/artworkinstructions.

Upload material, figures, and tables for online publication under the submission item "Supplementary Material" through the EES system. Be sure to change the description of the Supplementary Material to reflect the content; for example, Supplementary Detailed Methodology, Supplementary Figure Sx, Supplementary Table Sx.

Please order material such as Figures and Supplemental Figures separately in order of the callouts/first mentions in the text. For example: Figure 1, Figure 2; Supplemental Figure S1, Supplemental Figure S2, etc.

In the text be sure that you add behind the reference to the supplemental material "(Supplemental Table Sx; available at [URL/link*])." *To be provided by the production department.

NEW! Virtual Microscope Feature

After submission of your paper, if it contains conventional slide images, you may receive an invitation to complement the slide images with high resolution versions for use with the Virtual Microscope. After accepting the invitation, you will have the opportunity to upload the high resolution slide images using the Virtual Microscope authoring system and will receive instructions on how to include references to the high resolution slides in your manuscript. Readers of your final, published paper will be able to see the slides at their highest resolution using the Virtual Microscope and can link from the article straight to the slides. For more information about the Virtual Microscope: http://www.elsevier.com/about/content-innovation/virtual-microscope.

For uploading of the slide images or for support, please contact virtualmicroscope@elsevier.com

Imaging Data DICOM Viewer

If your paper contains images generated from DICOM data, you may receive an invitation from the Section editor(s) after submission inviting you to complement your online article by providing volumetric radiological data of a case, a specific example, or multiple datasets in DICOM format. Readers will be able to interact, adjust, display, and view the DICOM data using an interactive viewer embedded within your article. Specifically, the viewer will enable users to explore the DICOM data as 2D orthogonal MPR series, 3D volume rendering and 3D MIP. Specific enhancements include zoom, rotate and pan 3D reconstructions, section through the volume, and change opacity and threshold level. Each DICOM dataset will have to be zipped in a folder and uploaded to the online submission system via the "DICOM dataset" submission category. The recommended size of a single uncompressed dataset is 200 MB or less. Please provide a short informative description for each dataset by filling in the 'Description' field when uploading each ZIP file. Note: All datasets will be available for download from the online article on ScienceDirect, so please ensure that all DICOM files are anonymized before submission. For more information see: http://www.elsevier.com/about/content-innovation/radiological-data

Video data

Elsevier accepts video material and animation sequences to support and enhance your scientific research. Authors who have video or animation files that they wish to submit with their article are strongly encouraged to include links to these within the body of the article. This can be done in the same way as a figure or table by referring to the video or animation content and noting in the body text where it should be placed. All submitted files should be properly labeled so that they directly relate to the video file's content. In order to ensure that your video or animation material is directly usable, please provide the files in one of our recommended file formats with a preferred maximum size of 150 MB. Video and animation files supplied will be published online in the electronic version of your article in Elsevier Web products, including ScienceDirect: http://www.sciencedirect.com. Please supply 'stills' with your files: you can choose any frame from the video or animation or make a separate image. These will be used instead of standard icons and will personalize the link to your video data. For more detailed instructions please visit our video instruction pages at http://www.elsevier.com/artworkinstructions. Note: since video and animation cannot be embedded in the print version of the journal, please provide text for both the electronic and the print version for the portions of the article that refer to this content.

Permissions

Upload written permissions from the copyright holder to republish previously published material. Authors are responsible for obtaining and uploading any needed permissions and for clearly and completely identifying any overlapping material and/or quoted or paraphrased passages with proper attribution in the text to avoid plagiarism (including self-plagiarism). The Permissions FAQ for Authors is available at http://www.elsevier.com/authors/permission-seeking-guidelines-for-elsevier-authors. For assistance, please contact Elsevier's Permissions Helpdesk: +1-800-523-4069 x 3808; +1-215-239-3805; permissionshelpdesk@elsevier.com
Written, signed permission(s) from the patient or legal guardian is/are required for publication of recognizable photographs. Clearly state in your cover letter that patient consent has been obtained and is immediately available upon request. If it is impossible to obtain a consent form, the image(s) must be removed or sufficiently cropped to the area of interest only or otherwise changed so the patient cannot be recognized. However, blurring or placing bars over the eyes is no longer acceptable to eliminate the need for a signed consent form. The restrictions for photos have become very strict.

Letters to the Editor

Letters to the Editor should be a succinct comment pertaining to a paper(s) published in the Journal within the past year or to related topics. Provide a unique title for the Letter on the title page with complete contact information for the author(s). Double-space the text of the Letter. References, including reference to the pertinent article(s) in the Journal, should conform to style for manuscripts (see References). If accepted, the author(s) of the pertinent article(s) may be contacted to prepare a response to the comment.

Announcements

Announcements must be received by the Editorial Office at least 10 weeks before the desired month of publication. Items published at no charge include those received from a sponsoring society of the Journal; courses and conferences sponsored by state, regional, or national dental organizations; and programs for the dental profession sponsored by government agencies. All other announcements selected for publication by the Editor carry a charge of $60 US, and the fee must accompany the request to publish.

Virtual Microscope

The journal encourages authors to supplement in-article microscopic images with corresponding high resolution versions for use with the Virtual Microscope viewer. The Virtual Microscope is a web based viewer that enables users to view microscopic images at the highest level of detail and provides features such as zoom and pan. This feature for the first time gives authors the opportunity to share true high resolution microscopic images with their readers. More information and examples are available at http://www.elsevier.com/about/content-innovation/virtual-microscope. Authors of this journal will receive an invitation e-mail to create microscope images for use with the Virtual Microscope when their manuscript is first reviewed. If you opt to use the feature, please contact virtualmicroscope@elsevier.com for instructions on how to prepare and upload the required high resolution images.

Use of the Digital Object Identifier

The Digital Object Identifier (DOI) may be used to cite and link to electronic documents. The DOI consists of a unique alpha-numeric character string which is assigned to a document by the publisher upon the initial electronic publication. The assigned DOI never changes. Therefore, it is an ideal medium for citing a document, particularly 'Articles in press' because they have not yet received their full bibliographic information. Example of a correctly given DOI (in URL format; here an article in the journal Physics Letters B):
http://dx.doi.org/10.1016/j.physletb.2010.09.059
When you use a DOI to create links to documents on the web, the DOIs are guaranteed never to change.

Proofs
One set of page proofs (as PDF files) will be sent by e-mail to the corresponding author or a link will be provided in the e-mail so that authors can download the files themselves. Elsevier now provides authors with PDF proofs which can be annotated; for this you will need to download Adobe Reader version 9 (or higher) available free from http://get.adobe.com/reader. Instructions on how to annotate PDF files will accompany the proofs (also given online). The exact system requirements are given at the Adobe site: http://www.adobe.com/products/reader/tech-specs.html.
If you do not wish to use the PDF annotations function, you may list the corrections (including replies to the Query Form) and return them to Elsevier in an e-mail. Please list your corrections quoting line number. If, for any reason, this is not possible, then mark the corrections and any other comments (including replies to the Query Form) on a printout of your proof and return by fax, or scan the pages and e-mail, or by post. Please use this proof only for checking the typesetting, editing, completeness and correctness of the text, tables and figures. Significant changes to the article as accepted for publication will only be considered at this stage with permission from the Editor. We will do everything possible to get your article published quickly and accurately. It is important to ensure that all corrections are sent back to us in one communication: please check carefully before replying, as inclusion of any subsequent corrections cannot be guaranteed. Proofreading is solely your responsibility.
