Abstract

YouTube has emerged as a popular platform for accessing educational content. However, its effectiveness has been a topic of debate in dental education. This study aimed to analyze the content and quality of YouTube videos focusing on Class II resin composite restorations. The first 100 videos of Class II resin composite information on YouTube were evaluated. The overall quality of the videos was assessed using the video information and quality index (VIQI) and Content Score based on Class II resin composite criteria. Videos with a score of less than the mean were recognized as low-content. No significant differences were observed between high- and low-content videos when the number of views, likes, duration, days since upload, viewing rate, and interaction index were investigated (p>0.05). The number of subscribers revealed a marginally significant difference (p=0.053). The high-content videos demonstrated higher mean values compared to the low-content videos in flow (4.6 vs. 3.8; p=0.0004), accuracy (4.3 vs. 3.3; p<0.0001), value (3.7 vs. 2.9; p=0.002), and precision (4.8 vs. 4.2; p=0.0002). The overall VIQI score was significantly higher (p<0.0001) in high-content videos (Mean 17.4; SD 1.5) compared to the low-content videos (Mean 14.2; SD 2.2). When the Content Score was assessed, high-content videos (Mean 9.9; SD 1.3) revealed a higher score (p<0.0001) than low-content-videos (Mean 4.2; SD 2.3). Most YouTube videos showcasing Class II resin composites serve as effective teaching tools. However, a significant number of videos with low content exist. Therefore, dental students should exercise caution when utilizing YouTube videos for learning purposes.
