Two Cases of Sleep Bruxism Successfully Treated with Yokukansan

Abstract

Bruxism is a common condition often seen in daily practice. Although interocclusal appliances are often used, there are no established treatments to eliminate bruxism. Here, we report two patients who complained of bruxism and insomnia. Based on the diagnosis of Kampo medicine, we thought that stress was involved in the background of both cases. Therefore, we prescribed them yokukansan, and their symptoms improved. These results suggest that yokukansan may be effective for sleep bruxism and insomnia.
