The objective of this study was to evaluate subjective symptoms from the temporomandibular system in patients with fibromyalgia. Two hundred and thirty-seven individuals with fibromyalgia affiliated to the Stockholm Rheumatologic Association were included in the study. A questionnaire about symptoms of temporomandibular disorders (TMD) was mailed and returned by 191 (81%). The participants reported frequent and severe symptoms of TMD, 94% reported local pain from the temporomandibular system with a mean duration of 12 years. The most frequent sites were the temple, temporomandibular joint and neck regions. General body pain had a significantly longer duration than TMD, which indicates that fibromyalgia starts in other parts of the body and later extends to the temporomandibular region. The severity of general pain scored significantly higher than local pain, but there was a significant positive correlation between the two conditions. High frequency, 73-78 %, of headache, facial pain and tiredness of the jaws was found and about fifty percent of the patients also complained about difficulties to open the mouth and to chew. Fibromyalgia is thus a probable cause of TMD. In conclusion this study shows that patients with fibromyalgia often suffer from symptoms of TMD, and that the intensity of the pain is correlated to general body pain. These findings indicate that fibromyalgia is one of the causes of TMD.
本研究的目的是评估纤维肌痛患者颞下颌系统的主观症状。纳入了237名隶属于斯德哥尔摩风湿病协会的纤维肌痛患者。一份关于颞下颌关节紊乱症（TMD）症状的问卷被邮寄出去，191名（81%）患者回复了问卷。参与者报告了频繁且严重的TMD症状，94%报告有颞下颌系统的局部疼痛，平均病程为12年。最常见的部位是颞部、颞下颌关节和颈部区域。全身疼痛的病程明显长于TMD，这表明纤维肌痛始于身体的其他部位，随后扩展至颞下颌区域。全身疼痛的严重程度得分显著高于局部疼痛，但两种情况之间存在显著的正相关。发现头痛、面部疼痛和颌部疲劳的发生率较高，为73 - 78%，约50%的患者还抱怨张口和咀嚼困难。因此，纤维肌痛可能是TMD的一个病因。总之，本研究表明纤维肌痛患者常伴有TMD症状，且疼痛强度与全身疼痛相关。这些发现表明纤维肌痛是TMD的病因之一。
