The aim of this study was to assess the prevalence of temporomandibular disorder (TMD) and associated factors in an adult population in southern Brazil. The population-based sample (n = 4.65) included participants from Passo Fundo, a town in southern Brazil. The Fonseca Anamnestic Index was used to establish the prevalence of TMD. Sociodemographic and pathophysiologic factors and those that could cause tissue injury (trauma) were investigated. Data were analyzed using the chi-square or Fisher's exact test and Poisson regression model (p < 0.05; 95%CI). The prevalence of TMD was 13.4%, and the most prevalent symptoms were pain in the neck and/or shoulders (30.1%), headache (26.0%), and presence of popping or clicking sounds (17.0%). None of the sociodemographic factors (sex, age, marital status, occupation, and education) were associated with the prevalence of TMD (p > 0.05). Among pathophysiologic factors, those associated with the prevalence of TMD were insomnia (PR: 1.83; 95%CI: 1.07-3.12), osteoporosis (PR: 2.50; 95%CI: 1.22-5.12), rheumatoid arthritis (PR: 1.99; 95%CI: 1.07-3.68), and xerostomia (PR: 1.36; 95%CI: 1.07-1.73). The factors that could cause tissue trauma/injury associated with TMD were sleep bruxism (PR: 2.16; 95%CI: 1.01-4.62), awake bruxism (PR: 2.44; 95%CI: 1.16-5.11), tongue pressure against the teeth (PR: 4.11; 95%CI: 1.95-8.65), and neck support of objects during work (PR: 2.94; 95%CI: 0.88-9.73). The prevalence of TMD was 13.44%, and it was associated with pathophysiologic factors and those that cause tissue trauma/injury, but not with sociodemographic factors.
本研究的目的是评估巴西南部成年人群中颞下颌关节紊乱病（TMD）的患病率及相关因素。基于人群的样本（n = 465）包括来自巴西南部小镇帕苏丰杜的参与者。采用丰塞卡记忆指数来确定TMD的患病率。对社会人口统计学和病理生理学因素以及可能导致组织损伤（创伤）的因素进行了调查。使用卡方检验或费舍尔精确检验以及泊松回归模型分析数据（p < 0.05；95%置信区间）。TMD的患病率为13.4%，最常见的症状是颈部和/或肩部疼痛（30.1%）、头痛（26.0%）以及出现弹响或咔嗒声（17.0%）。社会人口统计学因素（性别、年龄、婚姻状况、职业和教育程度）均与TMD的患病率无关（p > 0.05）。在病理生理学因素中，与TMD患病率相关的因素有失眠（PR：1.83；95%置信区间：1.07 - 3.12）、骨质疏松症（PR：2.50；95%置信区间：1.22 - 5.12）、类风湿性关节炎（PR：1.99；95%置信区间：1.07 - 3.68）以及口干症（PR：1.36；95%置信区间：1.07 - 1.73）。与TMD相关的可能导致组织创伤/损伤的因素有睡眠磨牙症（PR：2.16；95%置信区间：1.01 - 4.62）、清醒磨牙症（PR：2.44；95%置信区间：1.16 - 5.11）、舌头对牙齿的压力（PR：4.11；95%置信区间：1.95 - 8.65）以及工作时用颈部支撑物品（PR：2.94；95%置信区间：0.88 - 9.73）。TMD的患病率为13.44%，它与病理生理学因素以及导致组织创伤/损伤的因素有关，但与社会人口统计学因素无关。
