| Abstract: | ObjectivesTo evaluate the content, reliability, and quality of videos about orthodontic clear aligners on YouTube.Materials and MethodsResearchers used the Google Trends website to determine that the most frequently used search term for orthodontic clear aligners on the Internet was: “Invisalign.” A search was then conducted on YouTube using the key word “Invisalign.” From the first 140 results, 100 videos were selected for analysis. A 13-point content score was used to classify poor-content and rich-content videos, and the global quality scale (GQS) was used to examine quality of the videos. To evaluate reliability of the information, a five-question scale was used. The Mann-Whitney U-test, χ2 test, and Pearson correlation coefficients were used for statistical evaluations.ResultsOf the YouTube videos, 33 were classified as rich content and 67 as poor content. Most videos (73%) were uploaded by laypeople, and most uploaders (71%) were women. The most commonly discussed content was instructions (65%), followed by procedure (57%) and pain (52%). Regarding the GQS, most of the videos were evaluated as moderate quality (51%). Compared with the poor-content video group, the rich-content video group had a significantly higher GQS score (P = .004). There was no significant difference between the poor-content and rich-content groups regarding information reliability (P > .05).ConclusionsVideo content on YouTube relating to aligner orthodontics was generally insufficient. The quality of videos was moderate, but the reliability of information was generally poor. Specialists should refer patients to reliable sources of information. |
