Dental Panoramic X-Ray Detector

YOLO11-N model trained to detect dental pathologies on panoramic radiographs.

Classes

ID	Name	Description
0	caries	Dental caries (including deep caries)
1	periapical_lesion	Periapical lesion / apical periodontitis
2	impacted_tooth	Impacted and wisdom teeth

Performance

Trained on 9,928 panoramic X-rays, validated on DENTEX val set (46 images, 182 boxes).

Metric	Score
mAP50	0.622
mAP50-95	0.406
Precision	0.630
Recall	0.614

Training converged at epoch 27/57 (early stopping, patience=30).

Training Data

liodon-ai/dental-panoramic-xray-yolo — combined DENTEX + OralXrays-9 (CVPR 2025), 9,928 train images, 39,715 annotated boxes.

Files

File	Size	Description
best.pt	5.2 MB	PyTorch weights (Ultralytics)
best.onnx	10.1 MB	ONNX export for framework-agnostic inference

Recommended Inference Settings

Parameter	Value	Reason
conf	0.45	Filters weak detections — reduces noise without missing high-confidence findings
iou	0.35	Tighter NMS — prevents duplicate boxes on adjacent teeth
imgsz	640	Training resolution

At conf=0.25 the model over-fires on caries (adjacent teeth flagged together). At conf=0.45 output is clean and clinically readable.

Usage

from ultralytics import YOLO

model = YOLO("best.pt")
results = model("panoramic.jpg", imgsz=640, conf=0.45, iou=0.35)
results[0].show()

Or with ONNX:

import onnxruntime as ort
sess = ort.InferenceSession("best.onnx")

Per-Class Notes

impacted_tooth — highest quality class. Consistently detects impacted wisdom teeth with tight boxes and 0.66–0.84 confidence. Closest to clinical-grade.

periapical_lesion — fires correctly when present, but limited by small val set. Treat as a flag to look closer, not a diagnosis.

caries — directionally correct (right quadrant, right teeth) but recall is limited at panoramic resolution. Use as a screening hint, not a count.
