Therefore, this study assessed the content quality and reliability of YouTube videos related to oral appliance therapy for obstructive sleep apnea (OSA). Methods Videos were systematically searched on August 20, 2023, using terms determined through Google Trends. Videos were included based on predefined criteria and independently assessed by two researchers. Video demographics were extracted. Video quality was evaluated using audio‐visual (AV) quality, video information and quality index (VIQI), global quality score (GQS), and reliability using a modified DISCERN tool (mDISCERN). High and low‐content videos were defined based on the customized 10‐point scoring system. Inter‐ and intra‐examiner reliability of scoring system were calculated.
