This present study aimed to evaluate the education of YouTube videos about wisdom tooth surgical removal for viewers. In this study, the term "wisdom tooth surgical removal" was searched on YouTube. After excluding duplicates, irrelevant videos, non-English-language videos; 92 relevant videos in English were independently examined by 3 reviewers. The videos were categorized as 'poor', 'moderate' and 'excellent' by scoring 9 points in order to evaluate the information they provided to the audience. Chi-square test was performed for categorical variables and differences between groups were compared with ANOVA-Kruskal Wallis. Correlations were analyzed using Pearson and Spearman test. Statistical significance was set P < 0.05. Majority of the videos (63%, n = 58) were uploaded by layperson for sharing personal experience, 19.6%, (n = 18) healthcare professionals (dentist, orthodontist, surgeon). There were 64 (69.6%) not useful videos, 19 (20.7%) moderately useful videos, and 9 (9.8%) very useful videos. There is no significant correlation between efficiency ratio and source of upload (P > 0.05). There is a significant relationship between efficiency ratio and interaction index (P = 0.019 < 0.05). Interaction indexes of poor useful videos are more than others. There is a significant relationship between the type of video and video demographics (all data' significant values < 0.05). Mean values of patient's experience are more than others. Healthcare professionals should be aware of the accuracy of information on the internet in order to guide patients.
