Lack of associations between occlusal and cephalometric measures, side imbalance in striatal D2 receptor binding, and sleep-related oromotor activities.

Abstract

Taking into account the low power of this retrospective, exploratory study, the results suggest that the orofacial morphology of sleep bruxers does not differ from that of non-bruxers. In addition, morphologic factors are probably not involved in the asymmetry in striatal D2 receptor distribution that was previously observed in association with sleep bruxism.
