Temporomandibular disorders (TMDs) are a prevalent group of musculoskeletal conditions affecting the temporomandibular joint, associated structures and masticatory muscles. The internet has become a primary source of health information for many patients; however, the readability, reliability, content and quality of online information on TMDs vary widely. A comprehensive synthesis of the characteristics and evaluation methods of such content is currently lacking.

This scoping review will follow the Joanna Briggs Institute methodology and be reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews checklist. Peer-reviewed primary and secondary studies assessing online information on TMDs will be included if they report on readability, reliability, content or quality. Eligible information sources include publicly available websites, videos and social media; discussion forums and printed materials will be excluded. No language, date or geographical restrictions will be applied. A three-step search strategy will be implemented across PubMed, Web of Science, Embase, PsycINFO and CINAHL, followed by citation tracking. Screening will be conducted independently by two reviewers using Rayyan. Data will be extracted with a pilot-tested charting tool and synthesised narratively and descriptively in tabular and graphical formats.

As this study will only use data from publicly available sources, ethical approval is not required. Findings will be disseminated through publication in a peer-reviewed journal, conference presentations and professional networks, with the aim of guiding the development of accessible and reliable digital resources for individuals seeking information on TMDs.
