Evaluation of the Content Quality of YouTube Videos Related to Endocrown

Aim: The purpose of this study was to evaluate and validate the popularity, content, reliability, and educational contribution of endocrown-related YouTube videos. Material and Methods: Two researchers systematically searched about endocrown on YouTube on April 10, 2023, by using the term “endocrown”. The top 250 of the search results were later added to the watchlist. Finally, 30 videos were included for analysis. Time since upload, duration, number of views, likes, number of subscriptions, number of views were recorded. The DISCERN instrument, the benchmarks established by the Journal of the American Medical Association (JAMA), and Global Quality Scores (GQS) were used to evaluate these 30 videos. Assumptions were checked and Kruskal Wallis tests were used to examine the differences between the averages of video features according to GQS and DISCERN scores. Results: According to the results of the analysis, a statistically significant difference was found between the averages of video features according to GQS groups and DISCERN scores (p<0.05). As a result of the analysis, a statistically significant difference was found between the video duration averages according to the JAMA scores (p<0.05). Kendal's Tau correlations were applied to examine the relationships between YouTube features and GQS, DISCERN, and JAMA scores. As a result of the analysis statistically significant relationships were found between time and GQS, DISCERN, and JAMA scores Conclusions: Despite the limited number of related videos, YouTube has shown similarity in the reliability and quality of videos on the topic of endocrown. As the duration of the videos increased, their reliability increased.
