Content analysis of YouTube videos regarding splint therapy for temporomandibular joint disorders

YouTube, like many other healthcare settings, is a widely used platform by patients. However, despite this popularity, variability in content quality and low reliability are significant challenges. This study aims to analyze the content quality and reliability of videos on YouTube™ regarding splints used in the treatment of temporomandibular dysfunction (TMD). The YouTube™ database was searched using the keywords "TMJ splint treatment" and "TMJ and splint." After applying the exclusion criteria, 100 videos were categorized based on the uploader's profile (healthcare professional/individual user). Video content was analyzed by two independent orthodontists using quantitative quality scales and standardized DISCERN and VIQI indices. The majority of the evaluated videos (64%) were uploaded by experts, and these videos were found to be statistically significantly superior to videos from individual users in terms of both overall content scores and DISCERN scores (p<0.05). The focus of the video content was observed to be predominantly patient experiences (60%). Importantly, high-quality videos also scored higher on measures such as views, likes, duration, and engagement index (p<0.05). Videos on TMJ and splint treatment on YouTube™ were found to be moderate in terms of content. The high reach of low-quality and potentially misleading videos has the potential to negatively impact patient perceptions and decisions about treatment. In light of these findings, physicians must play a significant role in patient education by producing evidence-based, accurate, and high-quality digital content.
