Figure 1

The change pattern of RANKL/OPG in the rat maxillae during the maxillary expansion. C: control group without treatment. E1: group in which the rats underwent midpalatal expansion for 1 day. E3: group in which the rats underwent midpalatal expansion for 3 days. E7: group in which the rats underwent midpalatal expansion for 7 days.Statistically significant.
