Quantitative analysis of the number of osteoclasts in the M1 pressure area after OTM in CB2−/− and WT mice. a TRAP staining results in the distal root compression side of the first molar. Scale bar: 50 µm. R, root; PDL, periodontal ligament; AB, alveolar; ↑ (Black arrow), TRAP positive cells. b Illustration of the tooth movement and osteoclast distribution in the maxillary first molar after OTM. F: The direction of Orthodontic force. c Statistic evaluation of TRAP positive osteoclasts in ROI, data are shown as mean ± standard deviation. Values are means ± SD. * P < 0.05 and **** P < 0.0001
