<p>The aim of this study is to evaluate the quality and reliability of the content in Turkish and English YouTube videos regarding the treatment of gingival recession. The terms “gingival recession treatment,” “receding gum treatment,” and “gingival recession surgery” were searched on the YouTube video platform using Turkish and English. 42 Turkish and 67 English videos that met the inclusion criteria were evaluated. Video title, origin, content type, duration, upload date, number of views, number of likes/dislikes, viewing rate and interaction index of the videos were recorded. The Global Quality Scale (GQS) and the DISCERN tool were used to evaluate the quality and reliability of the videos. In the study, the reliability scores of Turkish and English videos were found to be 2 and 3, respectively, according to DISCERN criteria. Both the content evaluation score and reliability scores of Turkish videos were found to be lower than those of English videos. The majority of Turkish videos were scored as GQS 1, while the majority of English videos were scored as GQS 2. 97% of both Turkish and English videos had low-quality content. In this study, we found that 97% of the evaluated videos had low-quality content. In order to prevent the spread of misinformation and to ensure that patients can access accurate information, it would be beneficial for educational institutions and specialists to prepare interesting videos with comprehensive content that are easy to understand for patients and share them on internet platforms such as YouTube.</p>
