NCT07731867

Brief Summary

The objective of this prospective, parallel-group, 1:1 randomized controlled trial is to evaluate the effectiveness of a generative artificial intelligence (AI)-based immersive training program, utilizing the Gemini platform, in improving endodontic risk disclosure and informed consent (RD-IC) quality, communication competence, self-efficacy, and reducing communication anxiety among undergraduate dental students during their clinical clerkship. Traditional pedagogical methods in dental education, such as case-based learning (CBL) and peer role-playing, often struggle to simulate the high-stakes interpersonal tension and technical complexity involved in specialized endodontic risk disclosure. Complications like instrument separation, pulp floor perforation, and acute flare-ups require clear, empathetic, and legally sound communication. While standardized patients (SPs) are effective, they pose severe logistical and financial constraints for large student cohorts. To address this gap, 96 fifth-year undergraduate dental students undergoing clinical rotation were recruited and randomly allocated to either the experimental group (1-month generative AI-based immersive training via the Gemini platform) or the control group (1-month conventional case-based learning). The AI intervention provided interactive, real-time conversational simulations across six high-stakes endodontic clinical scenarios, delivering instantaneous, personalized feedback on technical accuracy and empathetic delivery. The primary outcome evaluated was the RD-IC completeness score. Secondary outcomes included SEGUE communication framework scores, Self-Efficacy in Clinical Communication Scale (SCS) scores, Communication Anxiety Scale (CAS) scores, blinded standardized patient (SP) ratings, user satisfaction, and long-term clinical skill retention assessed at 1-month (T2-1m) and 2-month (T2-2m) post-intervention follow-ups.

Outcome Measures

Primary Outcomes (1)

  • Endodontic Risk Disclosure and Informed Consent (RD-IC) Completeness Score

    Evaluated via a validated 10-item checklist covering core indications, intraoperative complications, postoperative pain, long-term structural defects, poor prognosis, anatomical variations, sequential treatments, anesthetic allergies, systemic diseases, and poor compliance. Scores range from 0 to 100, with higher scores indicating superior technical accuracy and completeness in risk disclosure.

    Immediately post-intervention (T1, at 1 month after study baseline)

Secondary Outcomes (7)

  • SEGUE Framework Doctor-Patient Communication Competence Score

    Immediately post-intervention (T1, at 1 month after study baseline)

  • Clinical Communication Self-Efficacy Scale (SCS) Score

    Immediately post-intervention (T1, at 1 month after study baseline)

  • Communication Anxiety Scale (CAS) Score

    Immediately post-intervention (T1, at 1 month after study baseline)

  • Blinded Standardized Patient (SP) Core Clinical Communication Competence Score

    Immediately post-intervention (T1, at 1 month after study baseline)

  • AI Simulation Teaching Experience Scale Score

    Immediately post-intervention (T1, at 1 month after study baseline)

Study Arms (2)

Experimental Group

EXPERIMENTAL

Participants received a 1-month generative AI-based immersive training program using the Gemini platform, engaging in standardized interactive simulations of six high-stakes endodontic clinical scenarios with immediate personalized feedback.

Other: Generative AI-Based Immersive Training

Control Group

ACTIVE COMPARATOR

Participants underwent conventional case-based learning (CBL) targeting the same six endodontic scenarios over 1 month, involving group case discussions, faculty lectures, and standard informed consent reviews.

Other: Conventional Case-Based Learning

Interventions

1-month generative AI-based immersive training program utilizing the Gemini platform. Participants engage in 10-15 minute adaptive conversational simulations every 3-4 days covering six high-stakes endodontic clinical scenarios (such as acute pain management, instrument separation disclosure, and pulp floor perforation), receiving immediate personalized feedback on risk disclosure completeness and empathetic communication.

Experimental Group

1-month conventional case-based learning curriculum targeting the exact same six high-stakes endodontic clinical scenarios. Learning involves structured case discussions, faculty-led lectures, and review of standardized informed consent templates without adaptive conversational immersion or real-time AI feedback.

Control Group

Masking Details
Due to the educational nature of the intervention, blinding of students (participants) and instructors (care providers) was not feasible. However, single-blind assessment was enforced: independent faculty outcome assessors and standardized patients (SPs) were fully blinded to participants' group allocations during all evaluation sessions.
