Quality, reliability, and content of YouTube videos in Portuguese language about dental trauma

Objective: To evaluate the quality, reliability and content of YouTube videos in Portuguese about dental trauma. Method: An infodemiological study was developed in which the first 60 videos found on YouTube with the terms “dental traumatism”, “dental trauma” and “broken tooth” were analyzed. Repeated videos, longer than one hour, in a language other than Portuguese, not intended for the lay public, resolution of questions, songs, interviews, shorts, and other subjects were excluded. The content of the videos was rated using a 23-point scale that classified them into low, moderate, and high content. Reliability was assessed using the modified DISCERN scale and the overall quality was assessed using the Global Quality Score (GQS) scale. The numbers of likes, dislikes, comments and engagement were also accounted. Data were analyzed by Mann-Whitney and Spearman’s correlation test (α= 5%). Result: A total of 55 videos were included in the study. Most were posted by healthcare professionals (92.7%) and just over half (63.7%) were of good overall quality. There were moderate, positive, and statistically significant correlations between DISCERN and GQS scores (r=0.454), duration (r=0.575), and trauma content (r=0.510). Overall quality correlated moderately, positively, and significantly with content scores (r=0.604) and video length (r=0.467). Conclusion: A significant proportion of Portuguese videos on YouTube about dental trauma had low content, quality and reliability information.
