Assessing the Information Quality, Accuracy and Content of YouTube Videos on the Endo-Perio Lesions: A Cross-Sectional Stud

Aim: The aim of this study is to evaluate and analyse the quality, accuracy and content of videos about endo-perio lesions on the Youtube platform. Material and Methods: The search term "endo-perio lesions" was identified using the Google Trends application. On 1 December 2023, between 10:00 and 13:00, the term "endo-perio lesions" was searched on YouTube videos. The URLs of the first 200 videos were copied and the 40 videos that met the inclusion criteria were evaluated and scored for Global Quality Score (GQS), Modified DISCERN (mDISCERN) scale and completeness. Statistical analysis was conducted using descriptive statistics, as well as the Shapiro-Wilk and Mann-Whitney U tests. The significance level was determined as p<0.05. Results: The highest average GQS (mean±SD: 4,40 ± 0,52), mDISCERN (mean±SD: 4,80 ± 0,42) and completeness score (mean±SD: 4,90 ± 1,45), were found in videos posted by dentists or specialists. Among the content of the 40 videos, the most frequently mentioned topic was 'treatment of endo-perio lesions' (%82.5), followed by 'clinical and radiographic findings' (%77.5), 'etiological factors' (%62.5) and 'diagnosis' (%62.5). Other topics included, in decreasing order, 'classification of endodontic lesions' (%55), 'prognosis (%50)', 'microbiology' (%10) and 'pathology' (%10). Conclusion: It can be concluded that YouTube can provide valuable and useful information about endodontic lesions, within the limitations of this study. However, it is recommended to supplement this information with additional details on the prognosis, microbiology, and pathology of the lesions.
