Evaluation of cone beam computed tomography videos on Youtube

Purpose: Cone beam computed tomography (CBCT) is an imaging modality that plays an important role in dental practice. However, it is unclear whether videos with adequate and accurate information are available on a platform such as YouTube. The aim of this study was to determine whether CBCT videos posted on YouTube are indeed a valuable source of information. Methods: During the data collection process, we analyzed Google Trends searches using the keywords "cone beam computed tomography (in Turkish)", "dental tomography (in Turkish)", and "tooh tomography (in Turkish)" over the last 5 years. Then, 168 videos were analyzed as a result of searches on YouTube with these keywords. Among these videos, 48 were included in the study according to certain criteria. The number of view, viewing times, number of like, interaction index and viewing rate of the included videos were calculated. The upload source of the videos was categorized as clinic, dentist, educational channel, commercial, professional organization and TV channel. According to the upload source of the videos, the image quality, sound quality, narrator, purpose of the video, usefulness scoring and Global Quality Scale were evaluated. Results: The average number of views of the analyzed videos was determined as 1559.95, while the standard deviation value was determined as 2435.30. The average interaction index was 1.58, and the standard deviation value was 1.77. The average view rate was 377.55, and the standard deviation value was 956.88. Significant relationships were found between the upload source of the videos and the duration of the video, the number of subscribers of the channel that uploaded the video, and the number of likes (p=0.016, p=0.021, p=0.030, respectively). In addition, when the videos were evaluated in terms of their usability levels, significant relationships were found between the duration of the video, the number of likes, and the interaction index (p=0.001, p=0.009, p=0.015, respectively). Conclusion: This study reveals that CBCT videos posted on YouTube are generally of low quality and not informative. This highlights the need for reliable sources of information for dentists, patients, and future dentists.
