YouTube as an information and education source for use of mineral trioxide aggregate in endodontics: Quality and content analysis

Purpose: This study aimed to evaluate the content and educational quality of videos on YouTube about mineral trioxide aggregate (MTA) in endodontics.
Methods: YouTube (https: //www.youtube.com/) was searched for videos using the search term “endodontics, MTA,” which was determined using Google Trends. The video contents were analyzed under three categories (etiology, procedure, and prognosis) and the Global Quality Score (GQS). The descriptive statistics were evaluated, and the statistical analyses included Fleiss Kappa, Kruskal-Wallis, and Tamhane’s T2 test.
Results: The total number of videos, 67.5% were uploaded by specialists. The content completeness was significantly different among the uploaders (4.2±1.69). The highest mean GQS was found for videos published by specialists (4.03±1.09). The videos generally shared content about furcation perforation repair, management of teeth with open apex and apical plug technique, and product presentations.
Conclusion: Specialists should post more videos focused on information about MTA in root canal treatment and regenerative endodontics.
