Does YouTube™ Provide Adequate Information on Oral Health During Pregnancy?

Background This study aimed to assess the reliability, quality, and content of the information provided by YouTube™ videos on oral health during pregnancy to reveal the effectiveness of the videos for patients. Methodology This cross-sectional study was conducted by two experienced dental specialists. They initiated the study by searching for YouTube™ videos using the keyword 'pregnancy oral health'. The videos were then assessed based on various parameters, including origin, type, number of days since upload, duration, number of views, number of likes and dislikes, and number of comments. The specialists also calculated the interaction index and viewing rate. The reliability and quality of the videos were evaluated using the global quality scale (GQS) and modified DISCERN (mDISCERN) scales, while the content was assessed with the comprehensiveness tailor-made index. The data were analyzed with the Shapiro-Wilk, the Kruskal-Wallis, the post-hoc Bonferroni, and Fisher's exact tests. The significance level was set at P < 0.05. Results After reviewing initially 224 videos, 129 were included in the study. Health professionals were the publishers of most videos. A statistically significant positive correlation was found between content scores and video duration, number of comments, interaction index, and total DISCERN scores (p<0.05) (r=0.445, r=0.186, r=0.552, r=0.241, r=0.200, r=0.681, respectively). Statistically significant associations were found between GQS scores, video duration, number of comments, and total mDISCERN scores (p<0.05) (r=0.510, r=225, r=0.156, r=0.768, respectively). Statistically significant relationships were identified between the total content score, video source, and GQS (p<0.05). According to the total content score, 57.4% of the videos had a score of 2, 35.7% had a score of 1, and only 7% had a score of 0. Conclusions This study's findings underscore the significant variability in the scientific accuracy, content, and quality of health information on the Internet, particularly on YouTube™. It reveals that, while there are videos that provide rich content and high-quality information, there are also poor-quality and inadequate videos that may mislead patients. Health professionals should be aware of misinformation found on YouTube™ and ensure that patients always have access to accurate and reliable information.
