YouTubeTM as an Information Source for Regenerative Endodontic Treatment Procedures: Quality and Content Analysis

• The findings of the present study revealed that YouTube™ videos about REPs provide predominantly clinical information about patient chairside practice of REPs. • Majority of the videos about REPs were created by dental professionals. • Limited number of the videos were targeted at patients; therefore, informative videos for the patients about REPs are needed. Regenerative endodontic procedures (REPs) are one of the most important developments in dental practice, and in the era of Covid 19 pandemic, audio-visual contents of YouTube TM could be an information source for dental students, practitioners and patients. The aim of this study was to evaluate the quality, content and the demographics of YouTube TM videos about REPs. A search on YouTube™ was performed for REPs using “endodontic regeneration”, “pulp regeneration”, “regenerative endodontics”, “regenerative endodontic procedures”, “revascularization” and “revitalization” keywords. Totally 531 videos were found and 60 videos met the inclusion criteria. Following the assessment of the demographic features of the videos and the viewing rate of the videos were calculated. The content of the videos was evaluated based on the selected headings. The quality of the videos was assessed using the video information, quality index (VIQI), Global Quality Score (GQS) and DISCERN. The statistical analysis was performed using Spearman Correlation and linear regression analysis. Majority of the videos about REPs were created by dental professionals (91.7%). The most commonly covered topic was “clinical application” (76.7%). Total content score showed a positive correlation with total VIQI (r=0.795; p <0.001) and GQS (r=0.952; p <0.001). There were significant relationships between total content score, duration, GQS, total VIQI score and DISCERN. The findings revealed that YouTube™ videos about REPs provide predominantly clinical information about patient chairside practice of REPs and they could be considered as a supplementary information source for dental students and practitioners.
