YouTube as a source of information on adult orthodontics: a video analysis study

Abstract

Background: The purpose of this study was to evaluate the content and quality of YouTube videos on the topic of adult orthodontics.

Methods: Four Turkish keywords were searched on YouTube: ``orthodontic treatment in older ages'' (ileri yaşlarda ortodonti tedavisi); ``orthodontic treatment in adults'' (yetişkinlerde ortodonti tedavisi); ``braces treatment in older ages'' (ileri yaşlarda video information and quality index diş teli tedavisi); and ``braces treatment in adults'' (yetişkinlerde diş teli tedavisi). A total of 184 videos, ranked according to their relevance, were examined; out of these, 52 videos on the topic of adult orthodontics were included in the study. The information content score (with a scoring system consisting of 6 questions), reliability score, (VIQI), interaction index, and viewing rate of the videos were evaluated. The Mann-Whitney U test, Student's t test, and Spearman correlation coefficients were used for statistical analysis.

Results: Explanations provided on all videos included in the study were given by orthodontists, to inform patients. The average content score of the videos was 2.55 ± 0.99 out of 6, and the reliability score was 3.07 ± 0.92 out of 5. The VIQI score was found to be 16.05 ± 2.76 out of 20. A total of 34 (65%) of the videos were scored as as having poor content, and 18 (35%) had rich content. Rich-content videos were observed to be significantly longer (P < 0.05) and have higher VIQI scores (P < 0.001).

Conclusions: Although the information provided by YouTube videos about adult orthodontics was only moderately sufficient, this study found that YouTube is a reliable source of information.
