Oral function was evaluated in a group of 13 patients with muscle contraction headache (MCH), 7 patients with common migraine (CM) and 18 patients with 'combination headache' (CM + MCH) and in a control group of 25 normal persons who had never had a headache. Malocclusion and loss of molars were rare in both groups. Impaired denture function and joint disturbances were more frequent in the headache patients but not significantly so. Clenching and grinding teeth and tongue pressure were all significantly more common in headache patients. Tenderness of pericranial muscles was present in all headache patients with severity increasing in the order CM, MCH, CM + MCH; it was absent in all the controls. On the average 9 tender spots were found per patient. Pressure on tender spots evoked pain in other areas (referred pain) in 29 of 38 headache patients. The abnormal tonic hyperactivity in the masticatory muscles and the neck may be the cause of tenderness which again may be an important source of pain in these patients.
对13例肌肉收缩性头痛（MCH）患者、7例普通偏头痛（CM）患者、18例“复合型头痛”（CM + MCH）患者以及25例从未患过头痛的正常对照者进行了口腔功能评估。两组患者中错牙合及磨牙缺失情况均少见。义齿功能受损和关节紊乱在头痛患者中更为常见，但差异无统计学意义。紧咬牙、磨牙及舌压力在头痛患者中均显著更为常见。所有头痛患者均存在颅周肌肉压痛，严重程度按CM、MCH、CM + MCH顺序递增；所有对照者均无压痛。平均每位患者发现9个压痛点。38例头痛患者中有29例在压痛点施压时会诱发其他部位疼痛（牵涉痛）。咀嚼肌和颈部的异常紧张性活动亢进可能是压痛的原因，而压痛又可能是这些患者疼痛的重要来源。
