Purpose: This study aimed to assess the content, educational quality, and reliability of YouTube videos on endodontic retreatment to determine their usefulness for patients, students, and dental professionals.Methods: On February 15, 2025, a YouTube search was performed using the terms "retreatment, " "repeat root canal treatment, " and their Turkish equivalents.Among 85 videos screened, 35 met the inclusion criteria.Two observers independently evaluated them using a 13-item content checklist, the Modified DISCERN (mDISCERN) tool, and the Global Score for Educational Value (GSEV).Descriptive statistics, normality tests, Spearman correlation, t-tests, and Kruskal-Wallis tests were used for analysis (p<0.05). Results:The mean GSEV score was 5.07±3.21,suggesting moderate educational value.The average mDISCERN score was 2.44±0.95,indicating low reliability.Retreatment indications were the most commonly discussed topic (91.4%), while contraindications and intraoperative pain were rarely mentioned.Longer videos had higher GSEV scores.No link was found between video popularity and quality.Most videos were uploaded by independent dentists (57.1%).Conclusion: YouTube videos on endodontic retreatment show inconsistent quality and limited reliability.They can offer visual support but should not replace scientific resources.Dental professionals should help direct audiences to accurate, evidence-based content.
