The Nigerian Dental Journal, the official publication of the Nigerian Dental Association publishes peer reviewed, scientific articles relevant to the needs of dental, medical and other health professionals in Nigeria and other parts of the world. The Nigerian Dental Journal is published biannually and the contributions that are accepted for publications include clinical papers, research papers, review papers, technical notes (surgical techniques, technical innovations), case reports and letters to the Editor. Author(s) sending an article for submission should do so on the premise that the document has been perused and endorsed by all the authors and that all authors consented to the submission of the manuscript to the Journal. All the named authors must have made an effective input to the idea and design and/or analysis and interpretation of the data and/or the writing of the paper. All the authors must have judiciously checked its contents and have certified the final version presented for publication. Contribution merely in the acquisition of financial support or the gathering of data does not substantiate authorship.
Any manuscript concerned with human subjects, medical records, or human tissue that is submitted to the Nigerian Dental Journal should comply with the principles stated in the Declaration of Helsinki “Ethical Principles for Medical Research Involving ‘Human Subjects”, adopted by the 18th World Medical Assembly, Helsinki, Finland, June 1964, and as amended most recently by the 64th World Medical Assembly, Fontaleza, Brazil, October 2013.
The manuscript should contain a statement that the work has been approved by the appropriate Ethical Committee related to the institution(s) in which the work was performed, and that subjects gave informed consent to the work. The Nigerian Dental Journal requires institutional Ethics Committee approval for all human studies. For retrospective studies of records either a statement of approval or a statement of exemption from the Committee is appropriate. This statement should be provided upon submission of the manuscript. Studies involving experiments with animals must state that their care was in accordance with institution guidelines.
Written consents of the use of patient’s images in form of photographs, videos or any other form of description must be obtained from the patient (or parent, guardian or next of kin where applicable ) before submission of the manuscript. This must be provided to the Editorial Office on request. Even where consent has been given, identifying details should be omitted if they are not essential. If consent for publication has not been taken, private information on the patient included in any part of the paper (including all illustrations and videos) must be removed before submission.
Format of Journal
The format of the Nigerian Dental Journal follows the uniform requirements for manuscripts submitted to Biomedical Journals. These should be accompanied by a covering letter signed by all the authors and stating that the manuscript is not being considered for publication elsewhere and should be sent to the Editor –in-Chief of the Nigerian Dental Journal. All manuscripts submitted to Nigerian Dental Journal should be typed, double-spaced, on one side of A4 paper leaving at least 2.5cm margins all round. Pages should be numbered on the upper right corner beginning with the title page. Each manuscript component should begin on a new page in the following sequence: include Title Page, Abstract, Main Text, Acknowledgements, References, Tables, Figure Legends and Figures as appropriate.
Title Page: Should contain the following information in the following order : 1) the article title; 2) authors' full names with degrees or titles; 3) authors' institutional affiliations including city and country and e mail addresses and 4) name, address, telephone, fax and e-mail addresses of the author responsible for correspondence.
Abstract: Abstract of original research should be structured with objectives, materials and methods, results and conclusions briefly stated and not more than 400 words. Abstracts of case reports should not be structured but should briefly describe the case(s) reported, highlighting the unique features, treatment method employed, and conclusions drawn. The abstract page should bear 4-5 key words and a short running title of no more than 40 characters.
The Main Text: Should include Introduction, Methods, Results, Discussion and References.
Introduction: Should be brief and end with a statement of the objective of the study. A review article should be a major didactic article that clarifies and summarizes the exhaustive review of the literature.
Methods: Methods should describe clearly and concisely the method, including selection of observational and experimental subjects, apparatus and procedures in sufficient detail to allow the results to be duplicated.
Results: Results should be presented in a logical sequence in the text of the manuscript. Repetition of data in the text and in the tables should be avoided. Emphasis should only be on important observations.
Discussion: Discussion. Repetition of results should be avoided. Rather, there should be analytical discussion of the implications of the results and other observations as related to the study.
Acknowledgements: Authors are responsible for obtaining permission and approval from any one acknowledged by name, as readers may infer his/her endorsement of the data and conclusion. Only persons who have made contributions to the study and/or to the preparation of the manuscript should be acknowledged. Contributors to the article other than the authors credited should be specified. The source of funding for the study and any potential conflict of interests should be stated appropriately. Suppliers of materials/equipment should be mentioned and their address (town, state/county, country) included.

Tables and Figures
Tables: Tables should be consecutively numbered in Arabic numerals as cited in the text with a brief explanatory title supplied for each. Tables should be used only to show important points. Dual documentation in the form of tables and figures is not appropriate. Tables should be double spaced on separate pages and contain only horizontal rules. Tables should not be submitted as photographs and a concise descriptive title should be placed appear above each table, with any appropriate footnotes below. Care must be taken to ensure that all units are included and each table is cited in the text.
Figures: All illustrations (e.g. graphs, drawings or photographs) are considered to be figures, and should be numbered in sequence with Arabic numerals. They should be numbered and itemized after the Tables. All figures (abbreviated to Fig(s).) should spell out the text and their number be kept to a minimum. The features must be large enough to preserve their clarity after a decrease in size. Illustrations should preferably fill single column width (54 mm) after reduction, although in some cases 113 mm (double column) and 171 mm (full page) widths will be accepted
Line illustrations: All line illustrations should present a crisp black image on an even white background (127 x 178 mm (5 x 7 in), or no larger than 203 x 254 mm (8 x 10 in). The size of the lettering should be appropriate, taking into account the necessary size reduction. Line drawings should be professionally drawn; half-tones should exhibit high contrast.
Photographs and radiographs: The photomicrographs should show magnification and details of any staining techniques used. The radiographs should be clear and the area(s) of interest must be clearly indicated with arrows or other symbols.
Preparation of Electronic Figures for Publication: Although low quality images are adequate for review purposes, print publication requires high quality images to prevent the final product being blurred or fuzzy. Submit EPS (lineart) or TIFF (halftone/photographs) files only. MS PowerPoint and Word Graphics are unsuitable for printed pictures. For scanned images, the scanning resolution (at final image size) should be as follows to ensure good reproduction: lineart: >600 dpi; half-tones (including gel photographs): >300 dpi; figures containing both halftone and line images: >600 dpi.
Permissions: Permission of author(s) and publisher(s) must be obtained for the use of previously published material (text, photographs, illustrations) and must accompany the manuscript when it is submitted for consideration for publication. The Journal bears no responsibility for authors violating such rule.
