    Abstract:
    Background This study aims to evaluate the performance of OpenAI's GPT-4o in the Polish Final Dentistry Examination (LDEK) and compare it with human candidates' results. The LDEK is a standardized test essential for dental graduates in Poland to obtain their professional license. With artificial intelligence (AI) becoming increasingly integrated into medical and dental education, it is important to assess AI's capabilities in such high-stakes examinations. Materials and methods The study was conducted from August 1 to August 15, 2024, using the Spring 2023 LDEK exam. The exam comprised 200 multiple-choice questions, each with one correct answer among five options. Questions spanned various dental disciplines, including Conservative Dentistry with Endodontics, Pediatric Dentistry, Dental Surgery, Prosthetic Dentistry, Periodontology, Orthodontics, Emergency Medicine, Bioethics and Medical Law, Medical Certification, and Public Health. The exam organizers withdrew one question. GPT-4o was tested on these questions without access to the publicly available question bank. The AI model's responses were recorded, and each answer's confidence level was assessed. Correct answers were determined based on the official key provided by the Center for Medical Education (CEM) in Łódź, Poland. Statistical analyses, including Pearson's chi-square test and the Mann-Whitney U test, were performed to evaluate the accuracy and confidence of ChatGPT's answers across different dental fields. Results GPT-4o correctly answered 141 out of 199 valid questions (70.85%) and incorrectly answered 58 (29.15%). The AI performed better in fields like Conservative Dentistry with Endodontics (71.74%) and Prosthetic Dentistry (80%) but showed lower accuracy in Pediatric Dentistry (62.07%) and Orthodontics (52.63%). A statistically significant difference was observed between ChatGPT's performance on clinical case-based questions (36.36% accuracy) and other factual questions (72.87% accuracy), with a p-value of 0.025. Confidence levels also varied significantly between correct and incorrect answers, with a p-value of 0.0208. Conclusions GPT-4o's performance in the LDEK suggests it has potential as a supplementary educational tool in dentistry. However, the AI's limited clinical reasoning abilities, especially in complex scenarios, reveal a substantial gap between AI and human expertise. While ChatGPT demonstrates strong performance in factual recall, it cannot yet match the critical thinking and clinical judgment exhibited by human candidates.
