Title	Patients With Sleep Bruxism Are More Sensitive To And Show Signs Of Higher Levels Of Mental And Physiologic Stress
Clinical Question	Are patients showing signs or symptoms of sleep bruxism more sensitive to physiologic or mental stress, compared to patients who do not exhibit signs of sleep bruxism?
Clinical Bottom Line	Patients with sleep bruxism are more sensitive to and show signs of higher levels of mental and physiologic stress compared to patients without sleep bruxism. This is based on two case-controlled studies of 69 and 76 patients with and without sleep bruxism using two different methods of stress study. This is relevant for both general dentists and TMD specialists.
Best Evidence
PubMed ID Author / Year Patient Group Study type (level of evidence) 22199130 Abekura/2011 76 patients with and without sleep bruxism Case-Controlled Study Key results Patients with sleep bruxism may be more sensitive to stress compared to patients who do not show signs of sleep bruxism; stress sensitivity scores of patient groups with sleep bruxism were increased significantly (P < 0.01) after a stress task. 20205705 Giraki/2010 69 patients with and without sleep bruxism Case-Controlled Study Key results Within this study, subjects with sleep bruxism exhibited significantly (P < 0.01) higher levels of stress in the fields of ‘daily problems,’ ‘trouble at work,’ ‘fatigue,’ ‘physical problems,’ and ‘coping strategies.’ It also suggested that they dealt with stress in a negative way that could either but caused by or be the cause of sleep bruxism, either way there is a significant correlation between the two.

Comments on The Evidence	Validity: 76 patients and 69 patients were analyzed and their stress sensitivity and levels of stress were measured, respectively. The gold standard to determine stress sensitivity and levels was resting stress levels and standard questionnaire answers. A further spectrum of disease could be investigated. There were no competing interests.
Applicability	This CAT applies to patients with signs or symptoms of sleep bruxism, patients that are under high levels of stress, patients that are sensitive to stress or patients with TMD symptoms.
