Background: Sleep bruxism is the non-functional grinding or clenching of teeth during sleep. It may lead to tooth damage and myofascial pain. Although stress is discussed as a main causal agent, there is a lack of studies concerning coping strategies in patients with sleep bruxism. Purpose: The aim of the present study was to investigate whether bruxers, compared to non-bruxing individuals, apply maladaptive coping strategies. Method: Seventy-five sleep bruxers and 38 non-bruxers were selected by dental examination and tested by a German coping questionnaire (SVF78). Results: A significant difference in positive coping strategies was observed between the two groups. Bruxers reported less positive coping strategies, mainly less "reaction control""and "positive self-instructions." In general, males reported less negative coping strategies. Conclusion: The reported effects demonstrate a deficit of functional coping strategies in bruxers, whereas strategies that enhance stress do not seem to be associated with sleep bruxism. Findings do not admit the conclusion that there is a causal association of maladaptive coping and bruxism. However, they support the approach of a multidisciplinary therapy involving psychological treatment.
