Abstract　： [Abstract] It has been reported that bruxism and other masticatory activities suppress the effects of stress. In the present study, the effect of odor on the allostatic reaction of the body and bruxism activity was investigated in a stressed rat model. The results showed that restraint stress increased stress mediators such as cortisol, neutrophils, and lymphocytes. The attenuating effects of phytoncides on these stress mediators were observed in the neutrophil and lymphocyte counts in blood, while only a similar and nonsignificant tendency was observed in amines. The phytoncides had no effect on the stress-induced bruxism activity (SBA), although there was a slightly increasing tendency. The correlations between the length of SBA and neutrophils, lymphocytes, cortisol, and ulcer formation were calculated. It was confirmed that SBA, which was induced by stress, had a mitigating effect on allostatic overload in stressed rats. Aromatic treatment using the phytoncides reduced the blood levels of stress mediators such as neutrophils, and lymphocytes, but not bruxism activity.
