YouTube™ has become a widely used source of health information. This cross-sectional study aimed to analyze the quality of English language videos on oral leukoplakia available on YouTube™.
A YouTube™ search for oral leukoplakia was performed, leading to 1,690 videos. The first 100 results were examined for exclusion criteria, yielding 28 videos. The source, duration, views, likes, and dislikes of each video were recorded. Two oral medicine residents scored the videos for visibility, popularity, quality, utility, and reliability.
Videos were categorized into two groups: independent users or company advertisements (n = 21) and professional organizations or government agencies (n = 5). Analysis showed that, in general, videos were of low quality, usefulness, and reliability. Higher quality videos had more likes (p < .05, Mann-Whitney test). More reliable videos received more likes and presented a higher viewing rate and interaction index (p < .05, Mann-Whitney test).
There are few high-quality videos about oral leukoplakia on YouTube™. Oral medicine professionals and students should attempt to correct this deficit, as they are the holders of evidence-based knowledge and clinical experience.
YouTube 已成为广泛使用的健康信息来源。本横断面研究旨在分析 YouTube 上关于口腔白斑病的英文视频质量。
对 YouTube 上的口腔白斑病进行了搜索，共获得 1690 个视频。对前 100 个结果进行排除标准检查，得到 28 个视频。记录每个视频的来源、时长、浏览量、点赞和不喜欢。两名口腔医学住院医师对视频的可见性、知名度、质量、实用性和可靠性进行评分。
视频分为两组：独立用户或公司广告（n=21）和专业组织或政府机构（n=5）。分析表明，总体而言，视频质量、实用性和可靠性较低。质量较高的视频获得更多点赞（p<0.05，Mann-Whitney 检验）。更可靠的视频获得更多点赞，并且具有更高的观看率和互动指数（p<0.05，Mann-Whitney 检验）。
YouTube 上关于口腔白斑病的高质量视频很少。口腔医学专业人员和学生应尝试纠正这一不足，因为他们掌握着循证知识和临床经验。
