Human and Animal Rights:

• All patients and volunteers in a research project must be carefully informed about the aims of the research, the nature of the procedure, and any possible side effects or complications of the drugs/materials and interventions.

• Written informed consent from the participants or their legal guardians is necessary for any such studies. All patients who participated in the experimental investigation and subjects should be able to freely withdraw from the study any time without restrictions.

• When animals are used: a statement protocol approval by the official animal care and use committee must be included. All animal experiments should comply with the guidelines. Manuscripts may be rejected if the editor considers that the research has not been carried out within an appropriate ethical skeleton. In rare cases, the editor may contact the ethics committee for further information. 

• Acknowledgment of sources: Appropriate acknowledgment of the project of others must always be given.
• Disclosure and conflicts of interest: All manuscripts must contain disclosure of all relationships that could be observed as presenting a potential conflict of interest.
• Fundamental mistakes in the manuscripts: if an author discovers a significant error or inaccuracy in the published work, it is the author's obligation to sharp inform the journal editor or publisher (the Egyptian association of Endodontists) and collaborate with the journal editor to retract or correct the manuscript.
• Hazards and human or animal subjects: Statements of compliance are required when the project involves any chemicals, events, or equipment that have any unusual hazards inherent in their use, or if it involves the use of animal or human subjects.
• Use of patient photographic images or patients’ details: experiments on patients or volunteers require ethics committee approval in addition to informed consent, which should be reported in the manuscript. 

The corresponding author should also send a short declaration affirming that he/she receives all the responsibilities for authorship and takes primary responsibility for communication with the journal during the manuscript submission and publication process. And typically ensures that all the journal’s administrative requirements, such as providing details of authorship, ethics committee approval, clinical trial registration documentation, and gathering conflict of interest statements, are properly completed. The corresponding author should respond to editorial queries throughout the submission and peer review process in the appropriate time and should cooperate with any requests from the journal after publication. 

Each individual listed as an author should fulfill the authorship criteria recommended by the International Committee of Medical Journal Editors. (ICMJE - www.icmje.org). The ICMJE suggests that authorship be based on the following 4 criteria:

1. Significant contributions to the origin or design of the project; or the acquisition, study and interpretation of data for the work;
2. Drafting the effort or reviewing it critically for important intellectual content;
3. Final agreement of the version to be published;
4. approval to be accountable for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of the project are appropriately investigated and resolved.

All those designated as authors should meet all four criteria for authorship. Those who do not meet all four criteria should be acknowledged in the title page of the manuscript. In addition to being a part of the effort he/she has completed, an author should be able to identify which co-authors are responsible for specific other parts of the project.
