Reliability and quality of videos available on YouTube™ on bruxism

Abstract

Objective: To evaluate the reliability and quality of YouTube™ videos about bruxism. Methods: Google Trends was used to determine the widely used search term on YouTube™. A playlist was created(N=100) and the number of views(NV), like/dislike(G/NG), presenter, treatments, interaction rate(TI) and views(VZ), the quality criteria for consumer health information(DISCERN) and the global quality scale index(GQS) were used. Spearman's correlation coefficient was calculated. Results: 88 videos with NV 30572.72 and G/NG 1153.76/18.31; 68(77.3%) presenters were dentists. The most cited treatment was muscle-relaxing plates; TI was 6.4 and VZ was 3658.5. Reliability was 2.82(±0.852); 21 (23.9%) were of good/excellent quality. A weak correlation between reliability/NV(rs=-0.254), the GQS/likes(rs=0.270) and the GQS/dislikes(rs=0.292). Conclusion: Content about bruxism on YouTube™ is diverse. Most of the content is presented by dentists. The information provided is moderately reliable.
