Accuracy and reliability of Manus, ChatGPT, and Claude in case-based dental diagnosis

Claude and Manus demonstrated numerically higher diagnostic performance and greater response stability compared with ChatGPT; however, these differences did not reach statistical significance and should therefore be interpreted cautiously. This variability across models highlights the need for larger-scale evaluations. These findings underscore the importance of considering both accuracy and consistency when selecting AI tools for integration into dental practice and curricula.
