![]() ![]() An additional search was performed with the search string: (OPG landmarks). The initial search string was: (panoramic anatomy). On 1 June 2022, a video search was performed on YouTube. The aim of this study was to evaluate YouTube videos that covered the radiographic anatomy in panoramic images, to reveal the common structures described by them and any associated inaccuracies, and to identify exemplar videos as potential learning resources for students and clinicians. There seemed to be few organized playlists on dental radiographic anatomy, and hence an appreciation of the video contents was warranted. Meanwhile, there are also YouTube channels on medical radiology education. However, most YouTube videos focused on the body trunk and the extremities but there was generally a lack of videos on head and neck anatomy. Initiatives such as the Human Anatomy Education Channel were launched to support independent learning on YouTube with reliable videos uploaded. For anatomical education, a recent survey in Ireland found that around 78% of undergraduates consulted YouTube as their primary source of anatomy videos. YouTube videos have been utilized by students to learn endodontic and oral surgical treatments. Besides evaluating the dentition, panoramic images could also visualize the jaw bones and midfacial structures, and hence the potential use for detecting non-dental conditions such as bone resorption under chin implants, osteoporosis and Eagle syndrome. ![]() With a variety of image enhancement options available in the software, the digital armamentarium could partly overcome some of the most common reasons for the rejects, such as lack of sharpness or low contrast. The overall reject rate of panoramic radiographs across the literature was about 4%. Nowadays, most panoramic machines in dental clinics generate digital radiographic images to be evaluated on computer screens. Panoramic radiography can be considered as one of the essential diagnostic tools for dentists. The maxillary sinus was the structure mostly involved in wrong information, particularly the wrong delineation of its posterior wall. The videos were of good quality in general, with some frequent shortcomings being lack of visual aid with skull and schematic diagrams, and lack of discussion on clinical relevance. On average, each video described 26 landmarks, including 12.3 from the midfacial region, 8.2 from the mandible, and 5.2 from soft tissue/air space/others. Most of them showed clear panoramic images and had clear tracing or delineation of the anatomical landmarks. Finally, 38 videos were included and analyzed. Videos were excluded if they were irrelevant (e.g., focusing on radiographic errors without covering the anatomy), elaborating mainly with drawings without showing the landmarks on panoramic images, duplicate videos, and non-English speaking. By screening the resultant videos and their related videos (recommended by YouTube as a list on the right of the screen), a total of 62 videos were screened. The objective of this study was to provide a content analysis on these videos. No prior study has examined the content of YouTube videos with regard to radiographic anatomy on panoramic radiography. The radiographic anatomy on dental panoramic images is essential knowledge for proper diagnosis and treatment planning purposes. ![]()
