Evaluation of Information Reliability and Quality of Youtube™ Videos About White Spot Lesions

Abstract

Objective: The aim of this study was to determine the quality and reliability of the information provided by YouTube™ videos about white spot lesion.
 Methods: YouTube™ videos were searched for the term 'white spot lesion' (WSL) by relevance. 142 videos about WSL were analyzed and 56 videos that met the inclusion criteria were evaluated. Video demographics (number of views, duration, number of likes, number of comments) viewing rate, primary purpose, video sources were determined and the reliability and the quality of the listed videos were evaluated with modified DISCERN (ModDISCERN) scale and the Global Quality Scale (GQS). Kruskall-Wallis, Mann–Whitney U test, Spearman’s correlation coefficients and Intra-class Correlation Coefficient were used for statistical analyses. 
 Results: The majority of YouTube™ videos analyzed on WSL were uploaded by YouTube™ channels (50%), with 29% uploaded by dentists and 21% by companies. The mean/standard deviation (SD) ModDISCERN score, showing the reliability of the information in the videos, was 2.71±1.22; and the mean/SD GQS value showing the video quality was 2.71±1.14. 25% of the videos’ GQS value was >3, and the reliability of the information in these videos was significantly higher than the videos with a GQS of ≤3 (3.93 vs. 2.31; P
