At `conf=0.45` output is clean and clinically readable. ## Usage ```python 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: ```python 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. ## Citatio...
