Quality Assessment of Apical Resection Videos on YouTube: A Joint Study of Oral Surgery and Endodontics

This report evaluated the content quality of videos about the apical resection on YouTube, which is a complex procedure to understand for untrained people. A YouTube search was conducted using the keywords ''apical resection'', 'root-end resection'' and ''apicoectomy'' and the first 100 videos that appeared in the relevance sort for each keyword were listed. The results were evaluated for inclusion and categorized by source, purpose, target, teller, and technical procedure information. An evaluation was made by one oral and maxillofacial surgeon and one endodontist independently. The quality of the videos was measured using Global Quality Score (GQS) and content via usefulness score (US). The adapted DISCERN was used to score the accuracy and reliability of the information source, which ranged from 0 to 5. Results were analyzed and interpreted statistically. Results from 89 videos showed that the doctor was the video source for 53.9% and professional information was the purpose for 70.8%. Root-end cutting information was given in 92.1% and retrograde cavity was mentioned in 38.2%. The usefulness score (US) of 69.3% was poor, 29.5% moderate and 1.1% excellent. Scoring tables analyzing among themselves showed a statistically significant correlation between US and DISCERN (r=0.623; p
