Research Abstract

The reaction types for psychological stress were evaluated by measuring change of the concentrations of salivary Chromogranin A caused by experimental psychological stress. Concurrently the oral habits of bruxism and teeth-contact were examined by original new questioners. It was suggested that the subjects divided into normal stress reaction type had relatively small amount of oral habits. The electromyographic activities of masticatory muscles were increased by experimental stress and oral habits might have been induced. The relationship between bruxism habits and subjective symptom or sign of temporomandibular disorders was suggested.
