Quality of free gingival graft content in youtube videos: Usability in patient information and student education

Background: The aim of our study is to evaluate the usability of the Free Gingival Graft (FGG) procedure, which is included in YouTube videos, in both patient information and student education.Material and Methods: A search was performed on YouTube on December 1, in 2022, using the search term "Free Gingival Graft". First 150 videos were pre-evaluated, and 67 videos were included in the study. The length of the videos, the number of views, the number of likes, the presence of animation and the number of months after uploading were evaluated. The quality of the videos was evaluated and analyzed with The Global Quality Score (GQS), Usefulness Score (US) and The Journal of American Medical Association (JAMA) scores.Results: A positive correlation was found between viewer interaction, video duration and quality scores. The median values of the quality scores were 2 for the GQS, 2 for the JAMA score and 1 for the Usefulness score. The level of quality scores was found to be insufficient (poor quality). There is a high level, positive and statistically significant correlation between the GQS and the Usefulness score (r=0.858 and p<0.001).Conclusions: YouTube videos containing the FGG procedure were found to be insufficient for both student educa-tion and patient information purposes.
