Background:
To analyze the content, reliability, and quality of relevant TikTok videos regarding orthodontic retention.
Methods:
Six relevant terms were searched on the TikTok social media Web site. Uploaded videos satisfying inclusion/exclusion criteria were assessed for the presence of nine predetermined content domains and categorized as "high-content" (≥5) or "low-content" (<5). Reliability was determined using the DISCERN instrument and quality by the Global Quality Score (GQS). Layperson videos were evaluated for themes using discourse analysis. Intraclass coefficients for content, DISCERN scores, and GQS were calculated for intrarater reliability. Statistical analysis was via IBM SPSS Statistics (version 27.0.0.0; SPSS Inc. Chicago, IL).
Results:
Orthodontists uploaded 37.8% and laypersons 34% of the 209 assessed videos. Just 22.1% of videos were considered to be 'high-content.' Quality of life issues related to retainer wear was the domain that was present least often in the videos provided by orthodontists (13.9%) and most often in those uploaded by laypersons (53.5%). High-content videos recorded greater mean GQS and DISCERN scores compared with low-content videos (P < 0.001). Strong positive associations existed between the number of domains present and DISCERN scores (rho = 0.808; P < 0.01) and between GQS and DISCERN scores (rho = 0.67; P < 0.01). Intraclass coefficient scores ranged between 0.92 and 0.98. Dissatisfaction with the need for long-term retainer wear was a prevalent negative theme in layperson videos.
Conclusions:
The content, reliability, and quality of TikTok videos regarding orthodontic retention were poor. The orthodontic profession must use TikTok effectively to ensure it delivers high-quality information relevant to laypersons' concerns.
