Submission of a manuscript to the Nigerian Journal of Restorative Dentistry indicates that all authors have read and agreed to its content and that the manuscript conforms to the journal’s policies.
Conflicts of interest/competing interests
All authors of a manuscript must disclose any conflicts of interest they may have with the publication of the manuscript or an institution or product that is mentioned in the manuscript, which is important to the outcome of the study presented. Authors should also disclose conflicts of interest with products that compete with those mentioned in their manuscript.
Ethical approval of studies and informed consent
For all manuscripts reporting data from studies involving human participants or animals, formal review and approval, or formal review and waiver by an appropriate institutional review board or committee on ethics is required and should be described in the Method section. In addition, informed consent and assent (as appropriate) must be obtained for studies involving human participants.
Peer review is the system used to assess the quality of manuscripts before they are published. Independent researchers in the respective research areas assess submitted manuscripts for originality, validity, and relevance to help editors determine whether the manuscript should be published in the journal.
Nigerian Journal of Restorative Dentistry operates a transparent peer-review system where two or more content experts in the field of the article are engaged in the review process. Approval by two or more reviewers is needed for the final acceptance by the journal.
All submitted articles will be subjected to “Turn-it-in” for plagiarism check. Any submitted paper with a score above 25% will be deemed as plagiarized work and will not be processed further.New clinical tools and procedures
Authors reporting the use of a new procedure, technique, material, or tool in a clinical setting, e.g. as a case report, must give a detailed justification in the manuscript to support why the new procedure, technique, material, or tool was considered preferable to what is normally used in usual clinical practice to meet patients’ clinical needs. Such justifications will not be necessary in cases where the new procedure, technique, material, or tool has already been approved for clinical use at the authors’ institution. Authors are expected to have obtained ethics committee approval and informed patient consent for any experimental use of a novel procedure, technique, material, or tool where a clear clinical advantage was not evident before treatment.Research involving human embryos, gametes, and stem cells
Manuscripts that report experiments involving the use of human embryos and gametes, human embryonic stem cells, and related materials as well as clinical applications of stem cells, must include confirmation that all experiments were performed in strict compliance with relevant guidelines and regulations. The manuscript must include an ethics clearance certificate identifying the institution’s research ethics committee’s approval of the research work. Authors must confirm that informed consent was obtained from all recipients and/or donors of cells or tissues, where necessary, and describe the conditions of donation of materials for research, such as human embryos or gametes. Copies of approval and redacted consent documents may be requested by the Editor.Consent for publication
For all manuscripts that contain medical details and images of study participants, written informed consent for the publication of these details must be obtained from that participant (or their parent or legal guardian if under the age of 18years). However, in cases where images are unidentifiable and there are no details on individuals reported within the manuscript, consent for publication of images may not be required. If the participant has died, consent for publication must be obtained from their next of kin. The manuscript must include a statement that written informed consent for publication was obtained from the study participants.Trial registration
The Nigerian Journal of Restorative Dentistry requires registration of all clinical trials reported in submitted manuscripts. A list of suitable and publicly available registries is available on the ICMJE website as well as any of the primary registries that participate in the WHO International Clinical Trials Registry Platform, including the ISRCTN registry.
The trial registration number (TRN) and date of registration should be included as the last line of the abstract of submitted manuscripts.Registration of systematic reviews
The journal requires authors to register their systematic reviews in a suitable registry (such as PROSPERO) and the registration numbers must be included in the manuscripts.
