YouTube™ as a source of tooth avulsion information: A video analysis study

Evaluate the informative content in tooth avulsion videos intended for dentists available on YouTube™ and analyse their compliance with the International Association of Dental Traumatology (IADT) guidelines 2020.

Google Trends was used to identify the most searched term for tooth avulsion. Tooth avulsion-related videos in Brazilian Portuguese intended for dentists were searched on YouTube™ with a 12-month filter. Two raters reviewed these videos to extract their features and evaluate and qualify them with two 9-point checklists based on the IADT 2020 guidelines. The emergency steps for tooth avulsion at the accident site were assessed before, during and after clinical management; each step received 1 point if present and 0 points if absent. The final score ranged from 0 to 9 points on each checklist (18 points total), and the total score was used to classify the videos as having poor, moderate or rich content. Reliability and video quality were evaluated by an adapted version of the DISCERN tool and global quality scale (GQS), respectively. The data were analysed with the Mann-Whitney U-test, Pearson chi-square test, and the Kappa statistic (p < .05).

Of 60 videos, 8 were included. All were uploaded by dental professionals or undergraduate students; the average duration was 11 min (range: 0.40-65 min), and the average number of views was 56.75. Half the videos (50%) had maximum completeness scores for questions about emergency dentist referral before clinical management, and more than half (75%) had maximum completeness regarding the steps required during and after treatment. Rich videos had higher GQS scores (p = .049) without significant correlation.

Although most videos in Brazilian Portuguese were considered high-quality according to the IADT checklist, half of them presented partial absence of information regarding orientations at the accident site.
