Purpose: To evaluate the content and quality of videos on Youtube about the gummy smile. Materials and Methods: The keyword “gummy smile” was searched on Youtube.Videos were categorized as useful, misleading or personal experience based on their content. Videos were analysed to evaluate the quality and scientific reliability of the information using Global Quality Scale (GQS) and DISCERN criteria; and the understandability of this information using a tailormade custom comprehensiveness index (CI). The source and user interaction information for each video were recorded. Results: A total of 98 videos were included for analysis. The videos of 64 (65.3%) were considered as useful, 18 (18.4%) provided by misleading information, and 16 (16.3%) described personal experiences. The source of the videos was 66 (67.3%) of dentists/specialist, 8 (8.2%) of clinics/hospitals, 8 (8.2%) of TV channel/news agencies and 16 (16.3%) of were other.The GQS was <4 in most of the videos (92.9%). Based on 0-2 CI scores, 36, 51 and 11videos had a score of 0, 1 and 2, respectively. 87 (88.8%) and 71 (72.4%) videos showed clear aims and reliable sources of information according to DISCERN criteria, respectively. The mean GQS and CI were significantly higher in useful video content compared to misleading and personal experience videos (p<0.001). The mean GQS and CI in dentist-sourced videos were significantly higher than in TV and other-sourced videos (p<0.001). Conclusions: Although most of the videos were uploaded by dentists and contain accurate information, the content and quality of the information were insufficient. This study demonstrated that Youtube could still not be considered as a fully reliable source of information for patients on gummy smile.
