Quality and content analyses of YouTube videos related to medication-related osteonecrosis of jaws

Introduction
Medication-related osteonecrosis of jaws (MRONJ) is a condition that can cause pain and poor quality of life, requires professional approach for the maintenance of affected area, and is difficult to treat.

Objectives: The aim of this study was to analyze the accuracy and quality of information provided about MRONJ of YouTube videos.

Material and methods
A systematic search was conducted on YouTube using two keywords, including MRONJ and bisphosphonate-related osteonecrosis of the jaw. A total of 80 videos were evaluated. Video information and quality index (VIQI) were used to evaluate overall quality of videos. Comparison of categorical variables was performed with c2 and Fisher’s exact tests. Correlation between characteristics of videos was analyzed using Kendall’s tau-b correlation coefficient.

Results
Most of the videos were found to be uploaded by doctors/dentists or maxillofacial surgeons (38.8%). The majority of videos were low-content videos. Most of high-content score videos were loaded by academic health institutions/professional organizations. Relationship between VIQI and usefulness (r = 0.801, p = 0.000) was found to be high. A positive correlation was observed between length of the video and interaction index (r = 0.226, p = 0.005).

Conclusions
The majority of videos related to MRONJ contain videos with low-content/scores. Healthcare providers should be more engaged in providing accurate and reliable evidence-based information, and present their best practices information about MRONJ on YouTube.
