AI Virtual Patient Training for Dental Student History Taking

Summary

This randomized study evaluated whether an artificial intelligence-assisted virtual patient could support third-year dental students in practicing medical and dental history taking. Fifty-six students were assigned to either a Gemini-based virtual-patient training group or a conventional role-play group. Both groups completed four training sessions over 2 weeks using comparable clinical cases, practice time, and feedback criteria. The study compared changes in case-based history-taking competency as well as student satisfaction and perceived usefulness of the training methods.

Interventions

BEHAVIORAL

Gemini-Based AI Virtual-Patient Training

Students completed four 30- to 45-minute history-taking training sessions over 2 weeks using a Gemini-based artificial intelligence virtual patient. Students typed questions, documented elicited medical and dental history, and received automated rubric-aligned feedback after each simulated patient encounter. The virtual patient used predefined curriculum-based case information and disclosed information only in response to relevant student questions.

BEHAVIORAL

Conventional Role-Play Training

Students completed four 30- to 45-minute history-taking training sessions over 2 weeks with trained role-players or faculty members using standardized case scripts. Students practiced eliciting medical and dental history and received feedback guided by the same assessment rubric used in the virtual-patient group.
