PURPOSE: To depict and evaluate the characteristics, engagement, content, and quality of YouTube videos containing information about silver diamine fluoride (SDF).
METHODS: A total of 200 YouTube™ videos were selected and screened, and the video characteristics and engagement indicators were recorded. They were then reviewed for consistency with current professional guidelines on this topic. Two independent reviewers scored the videos using a customized 8-point scoring and 5-point Global Quality Scale (GQS) to assess the content information and the overall quality of each video. These videos were further classified into good, moderate, and poor videos. Kruskal-Wallis, Chi-squared, and Spearman's correlation tests were used for the statistical analysis.
RESULTS: 110 videos met the inclusion criteria. The median total content score was 3 (IQR = 4) and the median GQS score was 2 (IQR = 2). Less than half (n = 49; 45.5%) of the videos were uploaded by healthcare professionals. The video content was classified as good (n = 26; 23.64%), moderate (n = 43; 39.09%), and poor (n = 41; 37.27%). Good-quality videos have a significantly higher information content score than the other groups (P = 0.001). A strong correlation was found between the total content score and GQS score (rho = 0.970, P = 0.001). Longer duration, higher interaction index, and recent upload are associated with higher content and quality scores.
CONCLUSION: A considerable number of videos are available on YouTube about SDF treatment and are attracting public interest. The content and quality of these videos vary widely and are related to several factors.
