AI in the Chair: A Multi‐Centre Study of Doctor AI Answering Orthodontic Patient Questions

Key Points

This research investigates how well Doctor AI can answer frequently asked questions in orthodontics.
Utilized two AI models: ChatGPT-4 and DeepSeek-v3 to respond to 20 validated FAQs.
Responses were evaluated by expert panels across different language institutions.
Responses were rated on accuracy, comprehensiveness, detail, relevance, readability, and logic.
Both AI models scored above 8/10 across all evaluated dimensions.
ChatGPT scored higher in relevance compared to DeepSeek (9.01 vs. 8.69).
DeepSeek was rated higher for comprehensiveness (9.21 vs. 8.27).
No significant differences were found in accuracy, detail, readability, or logic.
Word counts between the two AI models were similar.

Abstract

Objectives: To investigate the performance of Doctor AI in answering frequently asked questions (FAQs) and to analyse the advantages and potential limitations. Methods: Twenty validated FAQs were entered into ChatGPT‐4 and DeepSeek‐v3 to compare the responses generated by the two models and their unmodified responses were assessed by expert panels from English‐, Chinese‐, and bilingual‐speaking institutions. Responses were rated across six dimensions: accuracy, comprehensiveness, detail, relevance, readability, and logic. Results: Both AI models generated high‐quality answers, scoring above 8/10 across all dimensions. ChatGPT outperformed DeepSeek in relevance (9.01 ± 0.33 vs. 8.69 ± 0.42; p = 0.005), while DeepSeek scored higher in comprehensiveness (9.21 ± 0.31 vs. 8.27 ± 0.65; p 0.100 for all). The word counts generated by ChatGPT (243.20 ± 58.27) and DeepSeek (257.35 ± 44.65) across 20 FAQs were similar ( p = 0.223). Conclusions: Doctor AI such as ChatGPT and DeepSeek are capable of delivering high‐quality responses to orthodontic FAQs. ChatGPT may provide more relevant answers, while DeepSeek offers greater comprehensiveness. Combining their outputs may improve patient understanding, but AI‐generated information should supplement, not replace, guidance from qualified orthodontic professionals.
