YouTube and Root Canal Irrigation Activation: Are We Learning Quality Content?

Abstract

This study aimed to evaluate the quality, reliability, and educational value of YouTube videos related to irrigation activation in endodontics. A total of 70 videos were analyzedusing the keyword ‘irrigation activation methods’. Videos were assessed using JAMA, DISCERN and GQS. Additional popularity metrics were recorded. Statistical analyses were performed using the Kruskal–Wallis and Spearman correlation tests (p < 0.05). The majority of videos demonstrated low content quality (68.6%, GQS ≤ 2) and weak accuracy (47%, JAMA ≤ 1). Longer videos were associated with higher quality scores, while popularity metrics did not show significant correlations with educational quality. A weak but statistically significant correlation was found between DISCERN and II (r = 0.261, p = 0.029). Positive correlations among JAMA, DISCERN, and GQS confirmed the consistency of these scales. Overall, the findings indicate that the quality of YouTube videos on irrigation activation varies considerably. While video length may enhance content quality by allowing for more comprehensive explanations, popularity indicators are not reliable measures of educational accuracy.
