Mapping evidence on implementation research in oral health: a global scoping review protocol

Oral health is an integral part of overall health and well-being, yet oral diseases remain highly prevalent, affecting an estimated 3.7 billion people worldwide. The greatest burden arises from periodontitis, tooth loss and oral cancers, while untreated dental caries continue to be the most common condition globally. Despite advances in preventive technologies, community-based programmes and clinical innovations, the global burden of oral diseases has not proportionately declined. This highlights a persistent evidence-practice gap in oral health, where effective interventions have not been translated into routine practice at scale. Implementation research provides a valuable lens to understand how oral health interventions can be adopted, adapted and sustained in diverse real-world contexts. However, evidence on implementation strategies, frameworks and contextual factors in oral health remains fragmented, with no comprehensive synthesis to date.

The review will follow Joanna Briggs Institute methodology for scoping reviews. A three-step search strategy will be applied to locate published and unpublished literature, including PubMed, Scopus, PsycINFO, Embase and grey literature sources such as World Health Organisation and Centers for Disease Control and Prevention publications, government and non-governmental organisation reports and academic theses. No date restrictions will be applied. Duplicates will be removed using Zotero. Following screening and full-text review in JBI SUMARI, data will be extracted using a predesigned tool and synthesised descriptively. Results will be presented in evidence tables and a narrative synthesis, supported by figures and thematic mapping of strategies, frameworks and contextual factors.

Ethics approval is not required for this scoping review. The findings will be disseminated through peer-reviewed journal publications and conference presentations.
