%X Introduction. Tension-Type Headache (TTH) is the most prevalent headache often associated with impaired function and quality of life. Temporomandibular Disorders (TMD) and TTH frequently coexist; characterized by pericranial tenderness and impact on daily life. We aim to apply a standardized questionnaire for TMD to characterize and analyse an eventual relation between sleep and oral health in TTH in a controlled design. Material and Methods. 58 consecutive TTH patients and 58 healthy controls were included. The Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) questionnaire, Oral Health Impact profile (OHIP) and questionnaires for sleep were applied. Results. TTH-patients had significantly higher pain scores ( ), decreased quality of life ( ), and higher total sleep scores ( ) compared to controls. Conclusion. For the first time we have identified a clear relation between TTH and TMD symptoms, depression, anxiety, poor sleep, and impairments of oral function in carefully classified patients. These findings indicate a close, but incomplete, overlap between TTH and TMD. Their underlying pathophysiological mechanisms need further research. 1. Introduction Epidemiological studies of sleep and headache disorders point to a close connection, but the causal relations are unclear [1]. Sleep is thus reported to be the most important alleviating factor in migraine and tension-type headache (TTH) and in contrast also a trigger factor in cluster headache [1]. Likewise, disturbed sleep and lack of sleep are reported to be important trigger factors for TTH and other headaches [1]. TTH is the most prevalent headache in the adult population affecting functional and psychosocial quality of life of the patients [2]. The socioeconomic burden of TTH is thus enormous, but very little scientific attention is directed to the underlying pathophysiology and treatment strategies. In a large Danish longitudinal epidemiological study, we have identified disturbed sleep as a very important risk factor for poor prognosis of TTH [2], but detailed analysis of the specific relations have not yet been conducted. We haves also addressed the issue of overlaps between headaches and Temporomandibular Disorders (TMD) [2, 3] in accordance with other studies [4]. More than half of the headache patients from our tertiary headache center also had TMD diagnosis according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) [5] and ICHD-II [6], indicating a close relationship, at least in some of the clinical manifestations of the painful conditions.
