Grounded in Ugandan Clinical Realities

A diagnostic decision-support system cannot be deployed on marketing claims; it must be backed by rigorous architectural validation. The UGDent platform was trained and evaluated on an extensive curated dataset of over 10,500 clinical dental images across six primary pathology categories (calculus, caries, gingivitis, mouth ulcers, tooth discoloration, and hypodontia).

Implementation Methodology

How to Pilot UGDent

For tele-dentistry platforms, NGOs, and district health centers seeking to upgrade their screening capabilities, we provide a structured, low-risk Phased institutional pilot program.

1 Phase I

Integration & Training

Connecting your clinical application to our FastAPI WebSocket backend. We provide localized training to community health workers on optimal smartphone camera sweeping techniques.

2 Phase II

Shadow Screening

Health workers utilize the React Native mobile app in a shadow capacity. The CLIP ViT model processes video frames and generates diagnostic predictions, logged and compared against manual diagnoses.

3 Phase III

XAI Clinical Auditing

Dentists review the Explainable AI attention maps to verify accurate lesion localization and rule out hallucinations based on lighting artifacts.

4 Phase IV

Full Deployment

Synthesis of pilot data into an impact report. The API transitions to active triage support, enabling confident referral of high-risk patients.

Technical Honesty

Understanding System Limitations

In clinical health-tech, overpromising is an ethical risk. We maintain total transparency regarding UGDent's current operational constraints.

Dataset Demographics & Imbalance

Class imbalance exists (e.g., Hypodontia under-represented). African intraoral demographics need expanded representation.

Multimodal Text Constraints

VLM constrained by absence of structured, clinically validated textual annotations in public datasets.

Hardware Dependencies

Sub-2-second inference currently requires GPU-accelerated cloud. Offline deployment requires aggressive quantization.

Immediate Next Steps

  • Curate proprietary African intraoral dataset
  • Apply Knowledge Distillation for edge deployment
  • Expand multimodal clinical annotations
