TikTok contains many videos about bruxism that may help raise the level of awareness on the topic. However, the quality of these videos' information represents the greatest concern.
The present cross-sectional analysis aimed to systematically assess the reliability and educational suitability of TikTok videos as a source of information on bruxism.
TikTok was searched for relevant videos uploaded until 6 March 2024, using the hashtags #bruxism, #grindingteeth and #jawclenching. Independent pre-calibrated operators conducted video inclusion and data collection, noting videos' characteristics, source, popularity, content, reliability (assessed through the DISCERN scoring system) and educational value (assessed through the Global Quality Score [GQS]). The Kruskal-Wallis test was adopted to compare videos from different sources. Videos with low and high educational value were compared using the Mann-Whitney U-test. Tests were considered significant when the p-value was < 0.05.
A total of 105 bruxism videos were analysed. Most videos covered bruxism management and clinical features, and more than 60% were uploaded by healthcare professionals. According to the DISCERN and GQS scoring, the videos' reliability and educational value were judged to be very poor and low, respectively, but on average they were higher for videos uploaded by healthcare professionals compared to those uploaded by laypeople. When comparing videos with high educational value to those with low educational value, differences were found in popularity, content and reliability.
The present results suggest the need for greater control of information disseminated on social media to fulfil its potential role in educating laypeople about bruxism.
TikTok上有许多关于磨牙症的视频，这可能有助于提高人们对该主题的认识。然而，这些视频信息的质量是最令人担忧的。
本横断面分析旨在系统评估TikTok视频作为磨牙症信息来源的可靠性和教育适用性。
在TikTok上搜索截至2024年3月6日上传的相关视频，使用标签#磨牙症、#磨牙和#紧咬牙。独立的预校准操作人员进行视频纳入和数据收集，记录视频的特征、来源、受欢迎程度、内容、可靠性（通过DISCERN评分系统评估）和教育价值（通过全球质量评分[GQS]评估）。采用Kruskal-Wallis检验比较不同来源的视频。使用Mann-Whitney U检验比较教育价值低和高的视频。当p值<0.05时，检验被认为具有显著性。
共分析了105个磨牙症视频。大多数视频涵盖了磨牙症的管理和临床特征，超过60%是由医疗保健专业人员上传的。根据DISCERN和GQS评分，视频的可靠性和教育价值分别被判定为非常差和低，但总体而言，医疗保健专业人员上传的视频比非专业人员上传的视频更高。在比较教育价值高的视频和教育价值低的视频时，发现受欢迎程度、内容和可靠性存在差异。
目前的结果表明，需要加强对社交媒体上传播的信息的控制，以充分发挥其在向非专业人员普及磨牙症知识方面的潜在作用。
