Condylar cartilage degeneration in rat models. Representative images of the first molar occlusion relationship in control and OD rats. H&E staining A (Ca: cartilage; Sb: subchondral bone; small superficial clusters is indicted by an “ → ”; fissures is indicated by an “*”) and Safranin O and fast green B analyses of glycosaminoglycans (red) in sagittal sections of the TMJ mandibular condylar cartilage layers. Scale bars: 50 μm. C Mankin scores and OARSI scores D in the control and OD groups. *P < 0.05, ***P < 0.005, ****P < 0.001. N = 6–8
