Teeth with FDI numbering on CT

Teeth segmentation on CT with FDI numbering: TotalSegmentator outlines each of the 32 teeth and its pulp, plus the jawbones, mandibular canals, maxillary sinuses, pharynx, bridges, crowns, and implants. Research groups use it to chart which teeth are present, measure tooth and pulp volumes, and map how close the mandibular canal runs to the roots. On PET or SPECT, the jawbone outlines read bone uptake around the teeth, set beside the volume of the bone.

Find answers to research questions like: Which teeth, by FDI position, are present or missing across a group? How do pulp and whole-tooth volumes differ between groups? How does jawbone uptake differ between groups?
