Pocket-Dentist - BRAR Bone Resorption Grading: leaderboard
Grading bone-resorption severity (Grade 1, 2 or 3 of the Bone Resorption Age Ratio index) from a panoramic dental radiograph and patient metadata, returned as a JSON object; 149 test radiographs from Shanghai Stomatological Hospital (BRAR dataset). From Pocket-Dentist (Bian et al., 2026), with zero-shot greedy decoding; macro-F1 over the three grades in percent, higher is better.
Metric: Macro-F1 (%; three bone-resorption grades from a panoramic radiograph and patient metadata; 149 test radiographs; zero-shot). Source: arxiv.org. Saturation forecast: Around February 2027. 14 models tracked.
