Abstract：
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.
摘要：
背景本研究旨在评估质量，可靠性,以及YouTube™视频中提供的有关坏死性牙龈炎（NG）的信息内容，演示视频对患者的有效性，并帮助牙医使用这个平台作为资源来正确指导他们的病人。方法本横断面研究由两名有经验的牙周病学家进行。他们通过使用关键字“坏死性牙龈炎”和“沟口”搜索YouTube™视频开始了这项研究。“描述性参数，如上传源，原产国,持续时间,上传日期,喜欢的数量，不喜欢,视图,和评论进行了评估。经过初步评估,计算观看率和交互指数。视频根据7分制分为高含量（HC）和低含量（LC）。使用全球质量量表（GQS）和视频信息和质量指数（VIQI）评估视频内容的质量。使用各种统计检验对数据进行了分析，显著性水平设置为p<0.05。结果最初,筛选了148个视频，50个符合纳入标准的NG视频被纳入研究.在50个视频中，28（56%）是由医疗保健专业人员上传的。总的来说,68%的视频（n=34）被归类为HC，32%（n=16）被归类为LC。最常见的话题是NG的临床症状和体征，86%(n=43)，虽然预防NG是最不常见的话题，26%(n=13)。视频持续时间之间存在统计学上的显着差异，自上传以来的时间，根据TCS评分和VIQI评分(p<0.05)。HC视频的视频持续时间和VIQI得分高于LC视频。LC视频的上传时间高于HC视频。TCS评分之间呈正相关，视频持续时间,和VIQI,以及GQS分数之间，视频持续时间,观看率,和VIQI。结论YouTube™上的大多数NG视频都是有用且全面的，但是他们的数量不足。低质量和不充分的视频可能会误导医生和患者。然而,这也为医疗保健专业人员提供了利用YouTube™作为教育工具的机会。牙周病专家应该上传更全面的视频，在提供高质量信息方面发挥更积极的作用。
