RESUMO
Background This study aims to evaluate the quality, reliability, and content of the information provided in YouTube™ videos on necrotizing gingivitis (NG), demonstrate the effectiveness of the videos for patients, and help dentists use this platform as a resource to properly guide their patients. Methodology This cross-sectional study was conducted by two experienced periodontologists. They began the study by searching for YouTube™ videos using the keywords "necrotizing gingivitis" and "trench mouth." Descriptive parameters such as the source of upload, country of origin, duration, upload date, number of likes, dislikes, views, and comments were evaluated. After this initial evaluation, the viewing rate and interaction index were calculated. Videos were categorized into high content (HC) and low content (LC) based on a 7-point scale. The quality of video content was assessed using the Global Quality Scale (GQS) and the Video Information and Quality Index (VIQI). The data were analyzed using various statistical tests, with a significance level set at p<0.05. Results Initially, 148 videos were screened, and 50 videos on NG that met the inclusion criteria were included in the study. Out of the 50 videos, 28 (56%) were uploaded by healthcare professionals. Overall, 68% of videos (n=34) were classified as HC and 32% (n=16) as LC. The most common topic was clinical symptoms and signs of NG, with 86% (n=43), while NG prevention was the least common topic, with 26% (n=13). Statistically significant differences were found between video duration, time since upload, and VIQI scores according to TCS scores (p<0.05). Video duration and VIQI scores were higher for HC videos compared to LC videos. The time since upload for LC videos was higher than for HC videos. Positive correlations were observed between TCS scores, video duration, and VIQI, as well as between GQS scores, video duration, viewing rate, and VIQI. Conclusions The majority of NG videos on YouTube™ are useful and comprehensive, but their number is insufficient. Poor-quality and inadequate videos may mislead practitioners and patients. However, this also presents an opportunity for healthcare professionals to leverage YouTube™ as an educational tool. Periodontologists should upload more comprehensive videos and play a more active role in providing high-quality information.
RESUMO
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.
