Abstract

Statement of problem: Sleep bruxism, characterized by teeth grinding during sleep, is often managed with an occlusal device. Despite the abundance of YouTube videos discussing occlusal device therapy, their educational quality remains unclear.

Purpose: The purpose of this process-based audit was to assess the educational value (EV), clarity (COI), reliability (ROI), understandability (UOI), and actionability (AOI) of information regarding occlusal device therapy for sleep bruxism in YouTube videos provided by dental professionals.

Material and methods: YouTube was searched systematically using 4 search terms. A total of 19 videos were identified using predetermined criteria. EV was assessed using a 4-point scoring system across 10 predetermined domains. A 3-point scoring system was applied to evaluate COI. Journal of American Medical Association (JAMA) Benchmark Criteria was applied to evaluate ROI. Patient Education Materials Assessment Tool for audio-visual material (PEMAT-A/V) was used to determine UOI and AOI. Descriptive statistics, interrater and intrarater reliability tests were conducted using a statistical software program.

Results: Most videos had been uploaded by general dental practitioners (95%) followed by orthodontists (5%). The mean number of reported domains was 4.68 ±2.73 (out of 10), with the highest scoring domain being "Indications of occlusal device" (1.24 ±0.87), and the lowest being "Cost of occlusal device" (0.00 ±0.00). Overall, the EV score per video was 5.61 ±5.10 (out of 30), while the COI score was 0.55 ±0.50 (out of 2). The ROI averaged 1.95 ±0.40 (out of 4), with "Attribution" scoring lowest (0.026 ±0.11) and "Currency" highest (1). Overall, the videos had a mean understandability of 66.6% and actionability of 45.6%.

Conclusions: Videos uploaded by dental professionals lack sufficient educational value pertaining to the cost of occlusal devices. The videos demonstrated low reliability regarding the credibility of sources and poor understandability and actionability.
