This study aimed to analyze the videos available on YouTube related to dentistry and the novel coronavirus (COVID-19), as there is no such analysis in the existing literature. The terms "dental" and "COVID-19" were searched on YouTube on May 9, 2020. The top 116 English-language videos with at least 300 views were analyzed by two observers. Data was saved for each video, including target audience, source, country of origin, content, number of views, time watched, average views, duration, like/dislike ratio, and usefulness. Total video information and quality index (VIQI) scores were calculated, consisting of flow, information, accuracy, quality, and precision indices. Non-parametric tests were used for analysis. The analyzed videos were viewed 375,000 times and totaled 20 h of content. Most videos were uploaded by dentists (45.7%), originated from the United States (79.3%), and contained information targeted towards patients (48.3%). Nearly half of the videos (47.4%) were moderately useful. For the usefulness of the videos, statistically significant differences were found for all indices as well as total VIQI scores. A comparison of the indices according to the relevance of the videos showed statistically significant differences in the videos' information and precision indices and total VIQI scores. The results of this study showed that dentistry YouTube videos related to COVID-19 had high view numbers; however, the videos were generally moderate in quality and usefulness.
本研究旨在分析YouTube上与牙科和新型冠状病毒（COVID-19）相关的视频，因为现有文献中尚无此类分析。2020年5月9日在YouTube上搜索了“牙科”和“COVID-19”这两个术语。两名观察者对浏览量至少为300次的前116个英语视频进行了分析。保存了每个视频的数据，包括目标受众、来源、原产国、内容、浏览量、观看时长、平均浏览量、时长、点赞/差评率以及有用性。计算了总视频信息和质量指数（VIQI）得分，包括流畅性、信息性、准确性、质量和精确性指数。采用非参数检验进行分析。分析的视频总浏览量为37.5万次，内容总计20小时。大多数视频由牙医上传（45.7%），来自美国（79.3%），且包含针对患者的信息（48.3%）。近一半的视频（47.4%）有一定用处。对于视频的有用性，在所有指数以及总VIQI得分方面均发现了统计学上的显著差异。根据视频相关性对指数进行比较，结果显示视频的信息性和精确性指数以及总VIQI得分存在统计学上的显著差异。本研究结果表明，YouTube上与COVID-19相关的牙科视频浏览量很高；然而，这些视频的质量和有用性总体上处于中等水平。
