Research Abstract

It is reported that malocclusion induces psychological stress and psychological stress cause imbalance in the autonomic nerve balance. However, it is unclear whether malocclusion adversely affects autonomic nerve balance. The aim of this study is to clarify the influence of malocclusion on the autonomic nerve balance. We collected the data of 51 orthodontic patients who expressed informed consent. Following orthodontic treatment, masticatory capacity and SDNN increased, and Ln(LF/HF) which was an index of the sympathetic nerve activity decreased. In addition, HF(n.u) tended to increase. Increase in masticatory function might lead to stress improvement.
