Introduction Digital and data–driven technologies are increasingly shaping preventive oral healthcare and dental education. While prior studies have explored large language model (LLM) performance in non–English examination settings, their role in benchmarking standardized clinical knowledge against real student performance under identical institutional conditions remains insufficiently examined. Methods This study evaluated GPT–4o, GPT–4.5, and DeepSeek-R1 using 300 standardized dental competency items from institutional examinations (2023–2025). Model performance was benchmarked against data from a real student cohort who completed the same examinations, and intra–model consistency was assessed across multiple independent trials. Results DeepSeek–R1 achieved the highest overall accuracy (92.33%), significantly outperforming GPT–4.5 and GPT–4o in 2023 and 2024, while showing comparable performance to GPT–4.5 in 2025. Model type was the predominant factor associated with accuracy differences, whereas knowledge domain did not significantly affect results. DeepSeek–R1 and GPT–4.5 also demonstrated greater response consistency than GPT–4o. Discussion These findings suggest that optimized LLMs demonstrate strong alignment with standardized examination criteria and student performance patterns, supporting their potential role as supplementary tools for curriculum evaluation in preventive dental education. Caution is warranted in generalizing these results beyond the single-institutional, text-only, Mandarin-language context.
A 90-day district pilot
- Days 1–15 · Appraise. Have the curriculum lead and a teacher read the methods and limitations. Record the study design, sample, comparator, outcomes and evidence gaps. Define a local question that the study can help inform.
- Days 16–30 · Design. Redesign one low-stakes assessment: require a first attempt, an AI-assisted revision, a source-check log and a short oral explanation. Use the same rubric for the comparison task. Name an accountable owner and set the baseline, success threshold and budget before implementation.
- Days 31–60 · Test. Start with a small voluntary cohort, preserve an accessible non-AI route and require teacher review. Use synthetic or de-identified examples; approve data handling and tool terms through district processes.
- Days 61–90 · Decide. Blind-score reasoning, factual accuracy and unaided transfer on a fresh task. Record suspected misconduct separately from demonstrated evidence. Compare with baseline, document uncertainty and stop or revise if learning worsens, access is unequal or critical errors persist.
The board decision brief
Report the learning problem, evidence quality, participating population, total cost including review time, measured benefit, errors, access differences and remaining uncertainties. Make a dated recommendation to stop, revise or expand. A positive perception survey alone does not establish learning improvement.
