Abstract Orthodontic tooth movement is triggered by orthodontic force loading on the periodontal ligament and is
achieved by alveolar bone remodeling, which is regulated by intimate crosstalk between osteoclastogenesis and
osteoblast differentiation. Whether the communication between osteoclasts and osteoblasts is influenced by
orthodontic compression stress requires further clarification. In this study, osteoclasts were differentiated for 10 days.
On day 4 of differentiation, the number of pre-osteoclasts peaked, as determined by the increased expression of
RANK and the number of multinucleated cells. After 24 h of compression stress loading, on day 4, the number of
osteoclasts increased, and the optimal magnitude of… More >
