Aims: This study aimed to evaluate and compare the reliability and quality of the information about gingival enlargements on YouTube and TikTok. Methods: Two popular video sites, YouTube and TikTok, were searched for gingival enlargement and gingival hyperplasia. The reliability and quality of the first 300 videos for each search term, which is 1200 videos in total, were evaluated by social media video content evaluation tools: Global Quality Score (GQS) for quality and modified DISCERN for reliability. Results: Health professionals uploaded 68.6% of the videos on YouTube and 54.5% on TikTok. It was observed that 50% of TikTok videos and 65.9% of YouTube videos were educational. In terms of quality, 2.7% of the videos on YouTube are of excellent quality, while in TikTok there are no videos of perfect quality. TikTok videos had considerably more views, likes, viewing rates, and interaction index scores than YouTube videos (P < 0.01). Conclusions: The videos and pieces of information on YouTube are more reliable and accurate in terms of gingival enlargement when compared to TikTok. Nevertheless, it was discovered that videos on both platforms were of poor reliability and quality in general. [ABSTRACT FROM AUTHOR]

Objectives: Even though tooth sensitivity is a prevalent dental issue today, more information is available to patients via social media concerning the subject. This study aimed to examine what patients may learn about tooth sensitivity from online videos on YouTube™ and evaluate the accuracy of the information given. Methods: In this cross‐sectional investigation, two experienced periodontologists used the keyword 'tooth sensitivity' to conduct an organized search into YouTube videos containing knowledge regarding dentin hypersensitivity. Videos' type, origin, number of days since upload, duration, number of views, likes and dislikes, and comments were all noted; the viewing rate and interaction index were calculated. Videos were graded based on their content. The DISCERN and Global Quality Scales were used to rate each video's level of quality and reliability. Results: After the initial 260 videos were examined, 199 were kept for additional study. Healthcare professionals, hospitals, and colleges posted the great majority of the videos. There was a significant positive relationship between the number of views and Total Content scores of the videos, the viewing rate, comments, and likes (p < 0.05). Significant relationships were obtained between total discernment, video type, source of upload, and global quality variables, and Total Content scores (p < 0.05). Conclusions: When looking for information on dentin hypersensitivity, patients might find watchable, reliable, and helpful videos on YouTube™. [ABSTRACT FROM AUTHOR]
