Evaluation of the Quality, Reliability and Usability of YouTube About ‘Guided Tissue Regeneration’

Background: The aim of this study was to evaluate the quality, reliability and usability in student education of videos on YouTube about Guided Tissue Regeneration (GTR). Materials and Methods: The YouTube platform was searched on 22 July 2024 using the term GTR. The first 500 videos were initially evaluated, and 131 videos were included in the study. For all videos, the duration of the video, total number of views, number of likes and dislikes, the number of streams to date since the time of upload, the source of uploads, and the subject of the video were recorded. The viewer interaction index, video power index, and view rate were calculated. The Global Quality Scale (GQS) was used to evaluate the quality of the videos, and the Modified DISCERN tool and Usefulness Scores were analyzed to evaluate reliability. Results: Statistically significant, positive relationships were found between the number of views, number of likes, number of followers, video duration, and GQS. Significant, positive relationships were found between DISCERN and Usefulness Scores and video duration. No statistically significant relationships were found between the video upload source and the GQS, Usefulness and DISCERN scores. Conclusion: It was observed that videos about GTR on YouTube are not of sufficient quality and reliability for the education of dentistry students or for patient information. Students and patients should be made aware that not all information they obtain from online video sources is completely accurate.
