Temporomandibular Disorders (TMD) encompass several entities, which may have differing etiologies. To test this hypothesis, we investigated risk factors for three diagnostic subgroups of painful TMD. Ninety-seven subjects with myofascial pain only, 20 with arthralgia only, 157 with both myofascial pain and arthralgia, and 195 controls without TMD pain met criteria for study eligibility. Investigated risk factors included both physical and psychological variables. Adjusted odds ratios were calculated by multiple logistic regression analyses. Myofascial pain occurring alone was significantly associated with trauma (Odds Ratio [OR] = 2.0), clenching (OR = 4.8), third molar removal (OR = 3.2), somatization (OR = 3.7), and female gender (OR = 4.2). Myofascial pain with arthralgia was significantly associated with trauma (OR = 2.1), clenching (OR = 3.3), third molar removal (OR = 4.0), somatization (OR = 5.1), and female gender (OR = 4.7). No significant associations were found for the small-arthralgia-only group.
颞下颌关节紊乱病（TMD）包含多种情况，其病因可能各不相同。为验证这一假设，我们调查了疼痛性TMD三个诊断亚组的危险因素。97名仅患有肌筋膜疼痛的受试者、20名仅有关节痛的受试者、157名同时患有肌筋膜疼痛和关节痛的受试者以及195名无TMD疼痛的对照者符合研究入选标准。所调查的危险因素包括身体和心理变量。通过多元逻辑回归分析计算调整后的优势比。单独出现的肌筋膜疼痛与创伤（优势比[OR]=2.0）、紧咬牙（OR=4.8）、拔除第三磨牙（OR=3.2）、躯体化（OR=3.7）以及女性性别（OR=4.2）显著相关。伴有关节痛的肌筋膜疼痛与创伤（OR=2.1）、紧咬牙（OR=3.3）、拔除第三磨牙（OR=4.0）、躯体化（OR=5.1）以及女性性别（OR=4.7）显著相关。仅有关节痛的小亚组未发现显著关联。
