Fig. 5From: The role of inhibition of osteocyte apoptosis in mediating orthodontic tooth movement and periodontal remodeling: a pilot studyHistological examination of osteoclasts on the compression area in experimental groups. No osteoclasts were seen in orthodontically unloaded groups (A, B). Many multinucleated cells were detected within the PDL, on the alveolar bone and dentin surface in both loaded groups (C, D), but with IG9402 treatment, multinucleated cells were not stained intensively red; they were TRAP negativeBack to article page
