Sleep bruxism is considered a sleep-related movement disorder. Bruxism is characterized by repetitive jaw-muscle activity, by grinding of the teeth and clenching the jaw. The objective of this study was to determine the association between anxiety, insomnia and excessive daytime sleepiness in a group of patients with clinical sleep bruxism. For this propose thirty-nine volunteers (14 males, 25 females) participated in this study. Participants were divided in two groups: sleep bruxism (n=20) and non-sleep bruxism(n=19) based on clinical evaluation. Beck Anxiety Inventory, Athens Insomnia Scale and Epworth Sleepiness Scale test were used to determine anxiety, insomnia and sleepiness respectively. The descriptive and inferential analysis shows that 75% of sleep bruxism participants displayed anxiety and insomnia. A positive correlation was found between anxiety and insomnia in sleep bruxism, rho=0.725, p<0.05. Excessive Daytime Sleepiness was present in 40% of the bruxers. In conclusions, the association of anxiety and insomnia with the presence of sleep bruxism is evident. These disorders induce sleep fragmentation that results in a poor quality of life.

Keywords: Sleep bruxism, anxiety, insomnia, excessive daytime sleepiness.
