Performance in answering orthodontic patients' frequently asked questions: Conversational artificial intelligence versus orthodontists.

Abstract

Objectives: Can conversational artificial intelligence (AI) help alleviate orthodontic patients' general doubts? This study aimed to investigate the performance of conversational AI in answering frequently asked questions (FAQs) from orthodontic patients, with comparison to orthodontists.

Materials and methods: Thirty FAQs were selected covering the pre-, during-, and postorthodontic treatment stages. Each question was respectively answered by AI (Chat Generative Pretrained Transformer [ChatGPT]-4) and two orthodontists (Ortho. A and Ortho. B), randomly drawn out of a panel. Their responses to the 30 FAQs were ranked by four raters, randomly selected from another panel of orthodontists, resulting in 120 rankings. All the participants were Chinese, and all the questions and answers were conducted in Chinese.

Results: Among the 120 rankings, ChatGPT was ranked first in 61 instances (50.8%), second in 35 instances (29.2%), and third in 24 instances (20.0%). Furthermore, the mean rank of ChatGPT was 1.69 ± 0.79, significantly better than that of Ortho. A (2.23 ± 0.79, P < 0.001) and Ortho. B (2.08 ± 0.79, P < 0.05). No significant difference was found between the two orthodontist groups. Additionally, the Spearman correlation coefficient between the average ranking of ChatGPT and the inter-rater agreement was 0.69 (P < 0.001), indicating a strong positive correlation between the two variables.

Conclusions: Overall, the conversational AI ChatGPT-4 may outperform orthodontists in addressing orthodontic patients' FAQs, even in a non-English language. In addition, ChatGPT tends to perform better when responding to questions with answers widely accepted among orthodontic professionals, and vice versa.
