Study Design and Limitations for Enterprise Context

This study provides valuable insights but comes with important limitations that an enterprise must consider for AI deployment. The datasets were derived from two distinct examination systems (U.S. Dental Decks and Chinese Dental Licensing Exam), each with differences in structure, content distribution, and subtopic coverage, limiting direct comparability. The cognitive difficulty of questions was not formally assessed, which could influence observed performance differences.

Furthermore, the human participant sample size was relatively small (n=10 per group), impacting the generalizability of findings to broader populations. Prior exposure to question banks was self-reported, introducing potential recall bias or incomplete disclosure. While efforts were made to minimize AI evaluation bias, subtle effects from prompt design or interaction conditions cannot be entirely ruled out. These factors necessitate caution when extrapolating these results to large-scale, diverse enterprise applications, especially for high-stakes medical decision-making.

Critical Implications for AI in Global Healthcare

The observed language disparity in ChatGPT-4o's performance carries critical implications for global medical education and patient safety. If non-English resources are not actively improved, the integration of AI risks creating a "digital divide," where non-English speaking professionals are disadvantaged by linguistic limitations, not medical aptitude.

From a clinical perspective, ChatGPT-4o's 16% performance deficit compared to OMS specialists on Chinese questions (71% vs. 87%) presents a serious patient safety warning. This level of discrepancy renders the model currently unreliable for autonomous clinical decision-making in non-English contexts. While it holds promise as a supplementary educational tool, its use must be strictly limited until performance parity with human specialists is established across all languages.

This finding offers actionable insights for AI developers: future models must prioritize the inclusion of diverse, native-language medical case reports and reasoning chains in their training data. This is crucial for ensuring the AI's clinical reasoning capabilities are robust and equitable across different linguistic and medical systems, mitigating the risk of exacerbating educational inequality and ensuring responsible AI deployment.
