With the aid of questionnaires symptoms of mandibular dysfunction and some general and oral conditions were studied in a group of previous patients and in a randomly selected population sample. From the two materials answers were obtained from 82 persons (81%) and 1.106 (91%) respectively. The results confirmed that women are heavily overrepresented in patient materials. This differs from the fairly equal sex distribution found in population studies of mandibular dysfunction. The most frequent symptoms of mandibular dysfunction were TMJ-sounds which appeared in 39 and 79% and pain on opening the mouth which appeared in 12 and 42% of the population and patient samples respectively. All symptoms of mandibular dysfunction, headache, clenching of the teeth and unilateral chewing appeared significantly more often in the previous patients, but the number of natural teeth did not differ in the two samples. The general state of health was poorer and general joint -- muscle symptoms were more common in the previous patients as well as in those of the population sample with symptoms of mandibular dysfunction. This finding suggests that functional disturbances of the masticatory system often may be related to impaired general health.
借助问卷调查，对一组既往患者和随机抽取的人群样本的下颌功能紊乱症状以及一些一般和口腔状况进行了研究。从这两份材料中分别获得了82人（81%）和1106人（91%）的回答。结果证实，在患者材料中女性的比例过高。这与下颌功能紊乱人群研究中发现的性别分布较为均衡有所不同。下颌功能紊乱最常见的症状是颞下颌关节弹响，在人群样本和患者样本中分别有39%和79%出现，张口疼痛在人群样本和患者样本中分别有12%和42%出现。所有下颌功能紊乱症状、头痛、咬牙和单侧咀嚼在前瞻性患者中出现的频率显著更高，但两个样本中的天然牙数量并无差异。既往患者以及有下颌功能紊乱症状的人群样本的总体健康状况较差，一般关节 - 肌肉症状更为常见。这一发现表明咀嚼系统的功能障碍往往可能与整体健康受损有关。
