The effects of intermittent PTH administration on alveolar bone loss and bone formation in the furcations. a Representative images of the alveolar bone area in each group (left panels; H&E stain; scale bar = 100 μm). Measurements of the alveolar bone area in each group (right panel). b Measurements of the osteoid area in each group. c Representative images of labeled alveolar bone surfaces by calcein and alizarin red fluorescence in the DP and DP + PTH groups (scale bar = 100 μm). Data are presented as the mean ± SE. *P < 0.05 compared with the C group. ^#P < 0.05. AB alveolar bone; BM bone marrow, PDL periodontal ligament
