Figure 2.

Effects of obesity on osteoclastogenesis in mice. A. Representative images of TRAP⁺ cells on the compression side of PDL and alveolar bone. B. Obese mice had significant reduced number of TRAP⁺ cells on 3 day and 7 day after force application. No significant difference was noted on day 5. R: root. PDL: periodontal ligament. AB: alveolar bone. The dark arrow indicated the force direction. The blue arrow indicated osteoclasts. Data represent as mean ± SD, n=5 in each group; **P<0.01, *P<0.05; NS: not statistically significant.
