YouTube™ and oral lichen planus: an appraisal of the educational quality of information

Abstract: The objective of this study was to analyze the quality of videos on oral lichen planus (OLP) available in YouTube™. A cross-sectional analytical study was conducted by searching the video sharing platform YouTube™. Videos aimed at clarifying the etiological and clinical characteristics, diagnostic criteria, treatment, and prognosis of OLP were included. A total of 481 videos were retrieved and 37 were included in the study according to the selection criteria established. Most of the videos evaluated (86.5%; n = 32) were produced by independent users. The average reliability was 1.8 and quality assessment classified only three videos (8.1%) as having good/excellent quality. A significant correlation was observed between the length of the video analyzed and its quality and reliability (p摘要：本研究旨在分析YouTube™平台上关于口腔扁平苔藓（oral lichen planus, OLP）的相关视频质量。本研究为横断面分析类研究，通过检索视频共享平台YouTube™开展。纳入的视频需旨在阐明OLP的病因学、临床特征、诊断标准、治疗方案及预后情况。最终共检索到481条视频，依据既定筛选标准纳入37条进行分析。在纳入评估的视频中，绝大多数（86.5%；n=32）由独立用户制作。本次评估的平均可信度得分为1.8，且仅3条视频（8.1%）被评为良好/优秀质量等级。研究观察到，分析视频的时长与其质量及可信度之间存在显著相关性（p
