The endothelin system has an important role in bone modelling during orthodontic tooth movement (OTM); however, little is known about the involvement of endothelin B receptors (ET in this process. The aim of this study was to evaluate the role of ETB in bone modelling during OTM using ETB knockout rats (ETB-KO). Thirty-two male rats were divided into 4 groups (n = 8 per group) the ETB-KO appliance group, ETB-KO control group, wild type (ETB-WT) appliance group, and ETB-WT control group. The appliance consisted of a super-elastic clo
