Core Outcome Set for trials on the prevention and treatment of enamel White Spot Lesions (COS-WSL)

Aim: To develop a core outcome set for trials on the prevention and treatment of enamel white spot lesions.
Background: Enamel white spot lesions (WSLs) are common in dental and especially orthodontic practice, which can impair both the health and aesthetics of affected teeth. Lots of different outcome measures have been used on trials on the prevention and treatment of enamel WSLs. Such heterogeneity in outcome measures hampers the comparison and synthesis of findings from different studies, which is essential for a better evidence base. It is therefore necessary to develop a core outcome set for trials on the prevention and treatment of enamel WSLs.
Methods: To summarise and analyse the current situation, all existing outcomes that have been used in trials on the prevention and / or treatment of enamel white spot lesions will be identified and summarised in a scoping review. Thereafter, qualitative interviews with patients who are undergoing or have had WSLs, as well as relevant dentists and orthodontists will be conducted to identify the outcomes that they consider important as a supplement to existing outcomes in the literature. For the Delphi process, the opinions of key stakeholders including patients, dentists / orthodontists, researchers, editors, policy-makers and industry representatives will be collected to determine the conceived importance of different outcomes. In the last stage, consensus meetings will be held to produce the final core outcome set
Dissemination: The final COS will be disseminated through academic journals and conferences.
