ChatGPT passes anatomy exam

---

Given the widespread use of ChatGPT by dentists and the uncertainty of its accuracy in answering dental anatomy questions, authors used the free GPT-3.5 version of ChatGPT to answer a comprehensive head and neck anatomy test with 75 single-answer multiple-choice questions obtained from the Dental Anatomy Coloring Book.

Results from this experiment were published Sept. 8 in the British Dental Journal. 

The authors manually inputted multiple-choice questions into the ChatGPT website and obtained answers along with explanations. This process was repeated three times, and the most frequent answer was considered correct.

To evaluate accuracy, the authors compared ChatGPT's answers with the answer key from the Dental Anatomy Coloring Book.

To successfully pass the exam, a minimum score of 70% was necessary. ChatGPT achieved a passing score, correctly answering 73.3% of the 75 questions without specialized training or reinforcement.

The authors concluded that head and neck anatomy is widely regarded as one of the most challenging subjects for dental students, due to its complexity and the involvement of numerous intricate structures. However, despite acknowledging certain limitations such as image-based questions processing, LLMs like ChatGPT have demonstrated promising results as an effective reference, virtual tutor and self-learning tool for this subject.
