Abstract　： [Abstract] Bruxism is generally defined as a parafunctional clenching and grinding action between the upper and lower teeth. During this activity, extremely strong forces can be applied for time periods exceeding those of functional mastication. These biomechanical loads create many dental problems, such as abfraction, hypersensitivity, periodontal distraction, and temporomandibular dysfunction. Researchers studying bruxism have long discussed psychic stress and emotional tension. It has also been indicated that an aggressive biting is associated with a significant attenuation of stress-induced increases in brain noradrenalin turnover, striatal DOPAC contents and stomach ulcer formation in experimental animals. The concept of stress management is based on the psychological background of bruxism and the benefits attributable to masticatory muscle activity in attenuating stress-related symptoms such as stomach ulcer. The clenching and bruxism function of the masticatory organ is an emergency exit during periods of psychic overloading. Therefore, the occlusion of the masticatory organ contributes significantly to an individual's ability to manage stress.
