AI Superiority in Detection
The HC-Net+ model achieved a remarkable AUROC of 94.2% in detecting stage II-IV periodontitis, significantly outperforming periodontal specialists who achieved 85.6%. This demonstrates AI's enhanced capability for accurate and reliable diagnosis. For enterprises in healthcare, this translates to improved patient outcomes and reduced diagnostic errors.
Mimicking Clinical Pathways
HC-Net+ is a deep-learning model designed to mimic clinical diagnostic pathways. It integrates localized tooth lesion analyses with a broad contextual understanding from orthopantomograms (OPGs). This human-like reasoning makes the AI intuitive for clinicians and ensures decisions are aligned with established medical protocols.
Robust Multicenter Validation
The model was rigorously tested with dual benchmarking against 382 clinically labeled OPGs and 760 radiographically labeled OPGs from four diverse international centers. It achieved >92.4% accuracy across all locations, proving its robust generalization capability and reliability in real-world, varied clinical settings.
Transformative Tool for Precision Dentistry
By surpassing specialist accuracy and making diagnostic expertise more accessible, HC-Net+ acts as a transformative tool. It significantly improves early periodontitis detection across all experience levels, enabling junior dentists to match specialist performance with AI support, leading to earlier interventions and better prognosis.

Stage II-IV Periodontitis Diagnosis Output
Case Study: Enhancing Early Detection in Primary Care
Challenge: Primary care dental practices frequently miss early-stage periodontitis due to time constraints, reliance on routine radiographs, and varying clinician expertise. This leads to delayed treatment, increased disease severity, and higher healthcare costs.
Solution: Integration of HC-Net+ into primary care workflows. The AI system provides automated, specialist-level radiographic analysis, identifying stage II-IV periodontitis with high accuracy from OPG images. It also offers interpretability through heatmaps, guiding clinicians to critical areas.
Result: Primary care dentists, including junior practitioners, significantly improved their diagnostic accuracy, matching or even surpassing specialist performance when supported by HC-Net+. This led to earlier and more consistent detection of periodontitis, enabling timely interventions and preventing disease progression. The system's rapid processing time (0.02s per image) also enhanced clinic efficiency without additional workload.
93.5%
Accuracy with AI Assistance for Specialists
When specialists leveraged HC-Net+ assistance, their diagnostic accuracy for stage II-IV periodontitis significantly improved from 85.1% to 93.5%. This demonstrates the AI's power to augment human expertise, particularly in challenging borderline cases.
