Chatbot Performance Metrics
This category covers the core quantitative and qualitative assessments used in the study, including validity (accuracy and completeness), consistency (reliability), and readability.
- Validity was assessed using both low (score ≥4) and high (score 5) thresholds, revealing differing strengths among chatbots.
- Consistency was measured by Cronbach's alpha, indicating acceptable reliability across models.
- Readability was evaluated using Flesch Reading Ease Score (FRES) and Flesch-Kincaid Grade Level (FKGL), showing significant differences.
Model-Specific Findings
Detailed insights into how each AI model (ChatGPT-4o, Google Gemini, Microsoft Copilot) performed across the various evaluation criteria.
- Google Gemini achieved the highest mean overall score and significantly greater high-threshold validity.
- ChatGPT-4o produced the most readable outputs but had lower overall mean scores and high-threshold validity, suggesting a 'safe but superficial' approach.
- Microsoft Copilot showed strong low-threshold validity but fell behind Gemini in high-threshold validity.
Implications for Patient Education
Discusses the practical implications of using AI chatbots for providing health information to patients, emphasizing the need for accuracy, completeness, and clarity.
- Misleading information, even in high-scoring outputs, poses risks to patient safety and clinical communication.
- The study highlights the trade-offs between readability and informational depth/accuracy.
- Professional guidance remains crucial despite the accessibility of AI-generated health information.

Statistical Comparison & Findings
Case Study: Misleading Information Risk
Context: Even high-scoring LLM outputs can contain misleading information, termed 'hallucination.' This poses a risk in healthcare contexts.
Example: In Q15 ('Can I get a root canal during pregnancy?'), Microsoft Copilot stated that X-rays are safe during pregnancy, which can lead to incorrect assumptions. Similarly, Gemini's response to Q25 ('Can I get a root canal if my face is swollen?') was clinically inaccurate regarding acute abscesses. Both received a score of 2, demonstrating potential for patient safety risks despite overall good performance.
Lesson: Despite high overall scores, critical evaluation is needed as 'safe but superficial' approaches (like ChatGPT-4o) might be safer than detailed but potentially inaccurate ones (like Gemini).

Implementation Roadmap
A phased approach to integrate AI into your endodontic practice, ensuring accuracy, safety, and efficiency.
Phase 1: Initial Assessment & Pilot
Evaluate current patient inquiry channels. Identify high-frequency questions suitable for AI chatbot support. Pilot selected chatbots with internal review by dental professionals.
Phase 2: Customization & Training
Integrate endodontic clinical guidelines and AAE materials into chatbot training. Refine responses for accuracy, clarity, and patient safety. Implement a feedback loop for continuous improvement.
Phase 3: Controlled Rollout & Monitoring
Deploy chatbots in a controlled environment (e.g., patient portal) with clear disclaimers that AI is not a substitute for professional medical advice. Monitor patient interactions and identify areas for further refinement.
Phase 4: Scaled Integration & Advanced Features
Expand chatbot functionality to cover a broader range of endodontic topics. Explore API integration for seamless integration with existing practice management systems and personalized patient journeys.
