Background: The purpose of this study is to explore the effects of CB2 on bone regulation during orthodontic tooth movement.
Methods: Thirty male mice were allocated into 2 groups (n = 15 in each group): wild type (WT) group and CB2 knockout (CB2) group. Orthodontic tooth movement (OTM) was induced by applying a nickel-titanium coil spring between the maxillary first molar and the central incisors.
