The submission file must be prepared in Microsoft Word document file format. The text is single-spaced; uses a 12-point font; Times New Roman format and tables are placed within the text at the appropriate points.

The manuscript should be submitted in separate files:

  1. title page file;
  2. main text file;
  3. figures files. 

The information below details the section headings that you should include in your manuscript and what information should be within each section.

  • Title page file

The title page should include:

  • Title of the manuscript which must be concise, descriptive, as short as possible without loss of clarity and abbreviations.
  • Keywords: authors are asked to provide up to five keywords, to be used as an aid to indexing. 
  • list the full names and institutional addresses for all authors.
  • Corresponding author name, full postal address, telephone and e-mail address.
  • Main Text File

The text is single-spaced; uses a 12-point font; Times New Roman format, All text should be in the form of paragraphs beginning with an indent, with no underlining in text divided into:

  1. Title
  2. Abstract structured (Aim/materials and methods/results/conclusions)
  3. Main body: formatted as introduction, materials & methods, results, discussion, conclusion
  4. References;
  5. Tables (each table complete with title and footnotes);
  6. Figure legends must be added at the end of the manuscript.


The Abstract should not exceed 250 words. Please minimize the use of abbreviations and do not cite references in the abstract.:

  • Aim: the purpose of the study
  • Materials and Methods: how the study was performed and statistical tests used
  • Results: the main findings
  • Conclusions: brief summary and potential implications

Main body


The introduction section should explain the background to the study, its aims, a summary of the existing literature and why this study was necessary or its contribution to the field.

-Materials and Methods

The materials and methods section should include:

  • the aim, design and setting of the study
  • the characteristics of participants or description of materials
  • a clear description of all processes, interventions and comparisons. Generic drug names should generally be used. When proprietary brands are used in research, include the brand names in parentheses
  • the type of statistical analysis used, including a power calculation if appropriate
  • ethical considerations should be mentioned here.


This should include the findings of the study including, if appropriate, results of statistical analysis which must be included either in the text or as tables and figures.


This section should discuss the implications of the findings in context of existing research and highlight the limitations of the study.


This should state clearly the main conclusions and provide an explanation of the importance and relevance of the study reported. 


In text citations should cite references in consecutive order using Arabic superscript numerals. Example for references writing within text: Hatem et al12 showed that SDF resulted in a 54% reduction in new caries experience. SDF is the most concentrated fluoride product commercially available for caries management.13

Cite references selectively, and number them in the order cited. Make sure that all references have been mentioned in the text. All references should be numbered consecutively in order of appearance and should be as complete as possible in Vancouver style.

  • Figures files

 Digital images should be in TIF or Jpg format at least 5 inches wide and at least 300 pixels per inch (118 pixels per cm). Do not embed images in a word processing program. For best results, avoid screening, shading, and colored backgrounds; use the simplest patterns available to indicate differences in charts.
