To assess the coverage of information about early childhood caries (ECC) available on YouTube videos in three different languages, regarding technical characteristics of videos and interaction metrics.
Search strategies were developed in English, Spanish, and Portuguese to make a comprehensive collection of videos from YouTube, encompassing 60 samples for each language, regarding all video types. The videos were assessed by a thematic checklist regarding 17 items on ECC. Videos were dichotomized according to the median of the thematic score and the nature of their authorship (health and non-health authors) to compare groups. The statistical analysis was performed using the Statistical Package for Social Science (version 25.0), applying Spearman's rank correlation coefficient and Mann-Whitney U test. P < 0.05 values were considered significant.
Among 120 videos meeting inclusion criteria, ECC aetiology and prevention information proved incomplete, with a median score of 5 (Q1-Q3 = 3-7). No correlation emerged between this score and other video characteristics. However, interaction metrics like views, likes, dislikes, and viewing rates displayed significant correlations. Health authors primarily created these videos, yet non-health author channels had more subscribers. Surprisingly, videos focused on the impact of regular sugary food and beverage consumption on ECC progression received the most attention.
Videos that presented information about the aetiology and prevention of ECC invariably focused on partial aspects of the disease. This highlights the need for better-quality educational videos and the importance of dental professionals in guiding patients toward reliable sources of information.
评估三种不同语言的 YouTube 视频中有关幼儿龋病 (ECC) 的信息覆盖范围，包括视频的技术特征和交互指标。
用英语、西班牙语和葡萄牙语制定了搜索策略，以便从 YouTube 上全面收集涵盖所有视频类型的每种语言 60 个样本的视频。使用主题清单评估视频中有关 ECC 的 17 个项目。根据主题评分中位数和作者身份（健康和非健康作者）对视频进行分类，以比较组间差异。使用社会科学统计软件包（版本 25.0）进行统计分析，应用 Spearman 等级相关系数和 Mann-Whitney U 检验。P 值<0.05 被认为具有统计学意义。
在符合纳入标准的 120 个视频中，ECC 的病因学和预防信息不完整，中位数评分为 5（Q1-Q3=3-7）。该评分与其他视频特征之间没有相关性。然而，交互指标如浏览量、点赞、差评和浏览率之间存在显著相关性。这些视频主要由健康作者创作，但非健康作者的频道拥有更多的订阅者。令人惊讶的是，聚焦于定期摄入含糖食物和饮料对 ECC 进展影响的视频获得了最多的关注。
呈现 ECC 病因学和预防信息的视频总是侧重于疾病的部分方面。这突显了需要更好质量的教育视频，以及口腔专业人员在引导患者获取可靠信息源方面的重要性。
