Objective: To compare how the quality of YouTube videos on tooth whitening uploaded by healthcare professionals and laypersons. Material and Methods: The video that was uploaded in a year was collected on YouTube using the keywords tooth whitening and dental bleaching. The exclusion criteria were duplicate videos, advertisements, no sound, too short duration, and lectures. The variables analyzed were likes/dislikes, viewers, interaction index, viewing rate, usefulness, global quality scale (GQS), and comprehensiveness score. Two observers reviewed the videos independently. Data were analyzed descriptively and analytically. Results: A total of 106 videos were selected, and most were uploaded by laypersons (70.8%). The observer reliability test showed excellent agreement with the intraclass correlation coefficient score minimum of 0.876. There were significant differences in dislikes (p=0.003), views (p=0.016), interaction index (p=0.010), usefulness (p=0.030), GQS (p<0.0001), and comprehensiveness (p=0.014) between healthcare professionals and laypersons. Videos made by laypersons had higher numbers of dislikes and viewing rates, whereas healthcare professionals were higher in usefulness, GQS, and comprehensiveness. Conclusion: Videos uploaded by laypersons provide low-accurate information despite being popular among viewers. Viewers need to be selective in seeking information from YouTube as a resource for oral healthcare decision-related tooth whitening.
Objectives: Currently, YouTube is still a favorite channel to get information for free. This study aimed to analyze the quality of Indonesian videos on YouTube uploaded by health professionals and non-health professionals about tooth whitening. Methods: The two keywords used in the search were tooth whitening (memutihkan gigi) and dental bleaching (bleaching gigi). From each keyword, 100 videos that appear first in YouTube and meet the inclusion criteria were taken. The inclusion criteria were videos according to keywords and in Indonesian. The exclusion criteria were duplicate videos, videos without likes and dislikes, conference or lecture videos that require a particular audience. Videos were analyzed by counting likes/dislikes, viewers, popularity, visibility, and DISCERN score. Two observers selected Videos independently, and their reliability was measured using Intraclass Correlation Coefficient (ICC) with a reference value > 0.8. Data analysis used the Mann-Whitney test to see the difference between health professionals and non-health professionals. Results: A total of 106 YouTube videos were selected according to the inclusion criteria from 200 downloaded videos. Most of the uploaders were non-health professionals (70.8%). There were significant differences in dislike, number of viewers, popularity, and DISCERN scores between health professionals and non-health professionals (p<0.05). Non-professional uploaders had higher dislike and visibility. For popularity, it is higher in health professionals. For DISCERN score, health professionals provide more accurate information. Conclusions: Information about tooth whitening or dental bleaching should be from a health professional to avoid inaccurate information. YouTube viewers to be more selective when choosing videos as a source of tooth whitening information.
