YOUTUBE AS A SOURCE OF INFORMATION ON FLUORIDE THERAPY

Internet platforms, such as YouTube, are gaining in importance as interfaces where health-related information can be stored and quickly accessed by people. The aim of this study was to assess the video content of YouTube videos about fluoride ion (F) therapy. A search of YouTube was performed using the keywords "fluoride treatment for kids," which is one of the most frequently terms for searching on F therapy. The data in the videos were extracted using a YouTube video application programming interface. For all the videos, the video length, date of upload, total views, number of likes/dislikes, and comments were collected. Calculations were made of the views per day, viewing rate, and viewers interaction. Two dentists independently reviewed the first 200 videos and evaluated their content, comprehensiveness, and accuracy. One hundred and fifty-five videos were included the study. The majority of the videos (n=69, 44.5%) were uploaded by a dentist/hygienist/specialist. The most mentioned subject was F varnish (n=66, 42.6%). Fourteen videos (9%) were assessed as being "very useful," 53 videos (34.2%) as "useful," 56 videos (36.1%) as "slightly useful," and 32 videos (20.6%) as "not useful." In our opinion, provided consideration is given to the source of an upload, YouTube can be a useful tool for learning about F therapy.
