There is disagreement about the association between missing posterior teeth and the presence of temporomandibular disorders (TMD). Here, the purpose was to investigate whether the number of missing posterior teeth, their distribution, age, and gender are associated with TMD. Seven hundred and forty-one individuals, aged 21-60 years, with missing posterior teeth, 386 with and 355 without TMD, were included. Four variables-gender, age, the number of missing posterior teeth, and the number of dental quadrants with missing posterior teeth-were analyzed with a logistic regression model. All four variables-gender (OR = 1.59, men = 1, women = 2), age (OR = 0.98), the number of missing posterior teeth (OR = 0.51), and the number of dental quadrants with missing posterior teeth (OR = 7.71)-were entered into the logistic model (P < 0.01). The results indicate that individuals who lose posterior teeth, with fewer missing posterior teeth but in more quadrants, have a higher prevalence of TMD, especially young women.
关于后牙缺失与颞下颌关节紊乱病（TMD）之间的关联存在争议。在此，目的是调查后牙缺失的数量、分布、年龄和性别是否与TMD相关。纳入了741名年龄在21至60岁之间、有后牙缺失的个体，其中386例患有TMD，355例未患TMD。使用逻辑回归模型分析了四个变量——性别、年龄、后牙缺失数量以及存在后牙缺失的牙象限数量。所有四个变量——性别（OR = 1.59，男性=1，女性=2）、年龄（OR = 0.98）、后牙缺失数量（OR = 0.51）以及存在后牙缺失的牙象限数量（OR = 7.71）——均被纳入逻辑模型（P < 0.01）。结果表明，后牙缺失的个体，缺失后牙数量较少但分布在更多象限的，TMD患病率更高，尤其是年轻女性。
