YouTube As an Information Source for Bioceramic‐Based Root Canal Sealers in Endodontics: A Cross‐Sectional Study

This study aimed to evaluate the content and quality of YouTube videos on bioceramic-based root canal sealers. A total of 43 videos were assessed using the Journal of the American Medical Association (JAMA), Global Quality Score (GQS) and Modified DISCERN (mDISCERN) measurement tools. Statistical analyses were conducted using the Kruskal-Wallis test, Spearman correlation analysis and multiple linear regression (p < 0.05). Videos uploaded by dentists had significantly higher GQS, mDISCERN, JAMA and Total Content Score (TCS) scores than those from other sources (p < 0.05). Videos with rich content showed higher GQS, mDISCERN and JAMA scores than those with poor content (p < 0.05). Although the number of comments demonstrated an individual association with GQS, the overall regression model was not statistically significant (p > 0.05). In conclusion, most videos on bioceramic-based root canal sealers were of poor to moderate quality and could have limitations in reliability.
