Content Analysis of YouTube Videos That Demonstrate Panoramic Radiography

Abstract

In this digital era, dental students often search for online resources for self-directed learning. YouTube is one of the most commonly sought online platforms for educational or instructional videos. No prior study has examined the validity of panoramic radiography videos available on YouTube. This study provides a content analysis of these YouTube videos. A search for relevant YouTube videos was conducted in April 2022. The search string was: (panoramic OR pan OR OPG) AND (dental OR dentistry OR X-ray). The first 100 videos that resulted from the search and their related videos were screened. Exclusion criteria included irrelevance (e.g., no demonstration of panoramic radiography procedures) and non-English videos. For each included video, the following parameters were recorded: image receptor type, patient age, patient type (real patient, animation, or phantom head), patient preparation procedures, machine preparation, patient positioning, and operator safety. The number of views, comments, likes, and channel subscribers were recorded, as well as the video duration and the age of the video. Forty videos were included and analyzed. Most of the videos demonstrated digital panoramic radiography with an adult patient. Procedures on the patient and machine preparations as well as patient positioning were generally explained well. However, most videos did not well-demonstrate operator safety details concerning the use of adequate personal protective equipment. View count, comment count, and channel subscriber count positively correlated with the like count. Clinicians and students should carefully critique the content of such instructional videos and refer to the contents from other sources such as user manuals and latest recommendations from local authorities.

Content Analysis of YouTube Videos on Radiographic Anatomy on Dental Panoramic Images

“…The view count only correlated to like count, channel subscriber count, and video age. In a previous study by our research team, the correlation between view count and like count was similarly reported for YouTube videos on demonstrating panoramic radiography [ 27 ]. These metrics did not necessarily reflect the content quality.…”

Is YouTubeTM the right address to get information on providing hygienic care for dental prostheses users?

“…Many studies evaluate the quality of the information provided by different social media platforms (16,17). Most of these studies investigated Youtube™ videos (18)(19)(20). Because of its rich content and easy access to information, most individuals prefer Youtube™ as a source for all kinds of information, including scientific opinions.…”

Are dental x-rays safe? Content analysis of English and Chinese YouTube videos

“…He has also previously published three articles that analyzed YouTube videos of dental radiography on radiographic procedures and radiographic anatomy. 12 – 14 …”

“… 6 – 11 Previous studies have evaluated the YouTube videos of dental radiography targeted for the professionals, such as radiographic procedures and radiographic anatomy. 12 – 14 However, it was of paramount importance to evaluate the videos dealing with the safety issue of dental x-rays targeted at the public. Therefore, this study aimed to reveal whether the videos reassured the public about the safety of dental radiographic examinations, assess the content covered by them and check for the presence of any inaccurate information.…”
