UFBA-425

We introduce UFBA‑425, a dataset of 425 anonymized panoramic dental X‑ray images with comprehensive pixel‑level instance segmentation masks, bounding boxes, and FDI‑system numbering annotations for every visible tooth. Accompanying metadata includes image resolution, count of teeth, individual tooth bounding box dimensions and coordinates, pixel density for each tooth, and presence of restorative appliances. UFBA‑425 aims to accelerate reproducible research in automated dental segmentation, detection, and numbering.
