Training Data

The model was fine-tuned on 2,494 dental patient cases covering:

Emergency dental situations
Periodontal disease management
Pediatric dental care
Oral pathology evaluation
Treatment planning and follow-up care

Performance

The fine-tuned model demonstrates improved:

Structured clinical responses
Evidence-based treatment recommendations
Appropriate urgency assessment
Patient safety considerations
Clinical guideline adherence

Limitations

This model is for educational/research purposes only
Not intended for direct clinical decision-making
Always consult with qualified dental professionals
May not cover all dental specialties or rare conditions
