This study aims to compare the effects of artificial intelligence-generated feedback and human instructor feedback on learning outcomes in preclinical restorative dentistry education. Third-year dental students performing restorative procedures on simulated teeth received either AI-generated feedback or instructor feedback during training sessions. The effects of the feedback methods were evaluated using practical performance scores, state anxiety levels, and student perception measures. The study investigates whether AI-generated feedback can serve as an effective educational support tool in preclinical dental training.
