Youtube as an Information Source for Practitioners on Direct Diastema Closure Procedures.

Background: The aim of the study was to analyze the content and quality of clinical diastema closure videos related to the direct resin composite restoration technique available on YouTube^TM. Materials and Methods: The videos were determined using the words "diastema closure," "teeth gap fill," and "teeth gap close" in the YouTube™ search section. 300 videos were reviewed, and 55 of them were included in the study. Demographics of videos, interaction index, and viewing rates were evaluated. The videos were analyzed in three parameters in terms of content score (CS), technical features (TF), and global quality scale (GQS). Results: The dentist accounts took the first place (51%) in the distribution of those who uploaded the videos. The mean values of the videos from the evaluation criteria were 8.3/15p for CS, 3.1/5p for TF, and 2.7/5p for GQS. There was a statistically significant positive correlation between the viewing rates, TF, and GQS values (P < 0.05). Conclusion: Operational videos of diastema closure with direct composite resin restoration treatments should be uploaded to YouTube™ after approval by experts. In addition, the TF of operational videos needs to be better. Students should be warned about videos which contain insufficient information. [ABSTRACT FROM AUTHOR]
