Statement of problem

Denture cleaning is indispensable to the maintenance of good oral and systemic health for denture users. Nowadays people often consult YouTube about health-related topics, including denture care. However, the quality of the information about denture care presented on YouTube is unknown.

Purpose

The purpose of this study was to evaluate the usefulness and quality of popular videos about denture care shared by different uploaders on YouTube and to evaluate the demographic characteristics of the videos.

Material and methods

Google Trends showed that “denture cleaning” was the most searched keyword on the topic. This keyword was used to search YouTube videos. Of the 200 most-watched videos, 109 videos were selected for analysis. Included videos were analyzed for their demographic data, including number of views; number of likes, dislikes, and comments; days since upload; duration and number of subscribers; an 8-point usefulness score system, a global quality scale (GQS); video sources; target groups; and primary purposes of the videos. Statistical analyses were conducted by using the Kruskal-Wallis test, post hoc Mann-Whitney U test, Pearson chi-squared test, and Spearman correlation analysis, which was used to investigate the relationship among total content score, GQS score, and video demographics. Cohen kappa statistics was used to measure the reliability of the investigator’s evaluations of the videos (α=.05).

Results

Based on the usefulness score, 59.6% of the videos were classified as poor, 32.1% as moderate, and 8.2% as good. No statistically significant differences were found among usefulness scores according to the video demographics, except lower GQS score of poor content videos (P<.001). The overall mean ±standard deviation GQS score was 1.92 ±1.0 out of 5. Videos were primarily uploaded (38.5%) from commercial companies. No statistically significant difference was found between video sources and usefulness scores (P>.05). The number of videos with poor content was significantly higher than the number with moderate and good content among the videos primarily intended for the education of health professionals (P<.001).

Conclusions

The majority (59.6%) of YouTube videos on denture care received poor content quality ratings, independent of video demographics. Therefore, YouTube is not suitable as the only source of information on denture care. Dentists and prosthodontists should take more responsibility for enriching the content of video-sharing platforms because this content can affect the behavior of patients and their attitudes about denture care.

YouTube 作为义齿护理信息源的评价

问题陈述

义齿清洁对于义齿使用者维护良好的口腔和全身健康是必不可少的。现在人们经常在 YouTube 上咨询与健康相关的话题，包括假牙护理。但是，YouTube 上提供的有关假牙护理的信息质量未知。

目的

本研究的目的是评估 YouTube 上不同上传者分享的关于假牙护理的热门视频的有用性和质量，并评估视频的人口统计特征。

材料与方法

谷歌趋势显示，“义齿清洁”是该主题中搜索次数最多的关键词。此关键字用于搜索 YouTube 视频。在观看次数最多的 200 个视频中，选择了 109 个视频进行分析。对包含的视频进行了人口统计数据分析，包括观看次数；喜欢、不喜欢和评论的数量；上传天数；订阅者的持续时间和数量；一个 8 分实用性评分系统，一个全球质量量表 (GQS)；视频源；目标群体; 以及视频的主要目的。使用 Kruskal-Wallis 检验、事后 Mann-Whitney U 检验、Pearson 卡方检验和 Spearman 相关分析进行统计分析，用于调查总内容得分、GQS 得分和视频人口统计数据之间的关系。

结果

根据有用性得分，59.6% 的视频被归类为差，32.1% 为中等，8.2% 为好。根据视频人口统计数据，在有用性得分之间没有发现统计学上的显着差异，除了内容不佳的视频的 GQS 得分较低 ( P <.001)。总体平均值±标准差 GQS 得分为 1.92 ±1.0（满分 5）。视频主要是从商业公司上传的 (38.5%)。视频来源和有用性分数之间没有发现统计学上的显着差异（P >.05）。在主要用于卫生专业人员教育的视频中，内容较差的视频数量明显高于内容中等和良好的视频数量 ( P <.001)。

结论

大多数 (59.6%) 关于假牙护理的 YouTube 视频的内​​容质量评级很差，与视频人口统计数据无关。因此，YouTube 不适合作为义齿护理信息的唯一来源。牙医和修复医生应该为丰富视频共享平台的内容承担更多责任，因为这些内容会影响患者的行为以及他们对假牙护理的态度。
