Objectives: This study aimed to evaluate the content, quality, and reliability of YouTube videos related to dental caries and nutrition. Methods: On October 1, 2024, six keywords associated with dental caries and nutrition were used to search YouTube, yielding 472 videos. After screening, 28 videos were included for analysis. The quality and reliability of these videos were assessed. Results: The analysis of information sources revealed that most videos were created by doctors or hospitals (61.0%), followed by for-profit websites or individual users (21.0%), with the least amount of content coming from medical websites or broadcast channels (18.0%). Reliability scores based on the information source showed that videos from medical websites or broadcast channels had the highest reliability (average score of 4.60), followed by videos from doctors or hospitals (average score of 3.88). Conclusions: Videos produced by medical websites, broadcast channels, doctors, and hospitals tend to provide reliable, high-quality information. Continuous monitoring, collaboration, and input from dental professionals are recommended for future content.
