TMJ Online: Investigating Temporomandibular Disorders as “TMJ” on YouTube

Abstract

Aim

As the understanding of temporomandibular disorders' (TMDs) etiologies and treatments develops from non-evidence-based to evidence-based approaches, the availability of sound information will likewise grow and need to be disseminated. The purpose of this study is to describe the content most commonly viewed in YouTube videos related to TMDs or "TMJ" and see if videos from different sources have different content

Methods

Video information was gathered by searching YouTube for the term "TMJ" and data was recorded related to descriptive information as well as content. Statistical analyses included Kruskal-Wallis H Test, Spearman's Rho, and univariate logistic regression

Results

The sources of upload were Consumer (n=62), Professional (n=29), and News (n=9). There were almost no statistically significant differences in content distribution among video sources. Videos garnered a total of 4,749,360 views, with an overall median of 7,014.5 views. About two thirds of the videos (68/100) explained what "TMJ" is, with a surprising third of Professional videos (9/29) not covering the subject. Roughly half of the videos mentioned at least one reason "TMJ" occurs (55/100) and seven in ten mentioned some kind of treatment (70/100). Video names mentioned a cure or treatment in 64 cases, while the other 36 referred to TMJ anatomy or "TMJ" etiology

Conclusion and Significance

Future research should focus on ways to popularize professional videos with reliable information for those who are searching on YouTube for advice related to "TMJ."
