Are YouTube Videos on Root Canal Retreatment Reliable Sources of Information?

Abstract

Background: The objective of this study is to systematically evaluate the quality, reliability, and
patient education potential of YouTube videos addressing root canal retreatment, and to investigate the interrelationships among the assessment tools applied.

Methods: The first 200 videos retrieved using the keyword “retreatment” on the YouTube platform up to March 2025 were screened according to predefined inclusion criteria, and a total of
58 videos were included in the study. Video content was assessed using the Global Quality Scale
(GQS), the Modified DISCERN tool, and a usefulness score. Additionally, parameters such as video
duration, like ratio, interaction index, and view rate were analyzed. Statistical analyses included
the Mann–Whitney U test, independent samples t-test, and Spearman correlation analysis.

Results: The mean scores of the evaluated videos were low for the Global Quality Scale (1.88 ±
0.92), Modified DISCERN (2.26 ± 1.02), and usefulness score (2.50 ± 1.14). None of the videos
were classified as having high content quality. A strong positive correlation was found between
video duration and both GQS (r=0.487, P < .001) and usefulness score (r=0.361, P=.005).
Additionally, a moderate negative correlation was observed between the interaction index and
the number of days since the video was uploaded (r=–0.53, P < .001).

Conclusion: Most YouTube videos of root canal retreatment are characterized by low content
quality and reliability. This poses a risk of exposing patients to inaccurate or insufficient information. It is essential for healthcare professionals to produce and recommend scientifically
grounded, high quality, and reliable content to support patient education effectively.
