To determine the prevalence of temporomandibular disorders and associated factors in an adolescent sample from Recife, Brazil.
A cross-sectional study was conducted with 1342 adolescents aged 10-17 years. The Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) was used by calibrated examiners to evaluate the presence and levels of chronic pain. To evaluate the socioeconomic conditions, the subjects answered the Brazilian Economic Classification Criteria (CCEB) questionnaire. Data were analyzed by means of binary logistic regression in SPSS.
The results showed that 33.2% of the subjects had TMD irrespective of age (p = 0.153) or economic class (p = 0.653). Statistically significant associations were found between TMD and female gender (p = 0.017), headache/migraine in the past six months (p<0.001), chronic pain (p<0.001) and chronic pain level (p<0.001). In the final model, logistic regression showed that the level of chronic pain and the headache/migraine in the past six months were related to the presence of TMD.
The prevalence of TMD was considered high (33.2%) and adolescents with chronic pain and headache in the past six months were more likely to have TMD.
The data contribute to the understanding of TMD among adolescents and to the development of preventive measures and polices to identify the dysfunction promptly.
在巴西累西腓的青少年样本中确定颞下颌关节紊乱的患病率和相关因素。
对 1342 名 10-17 岁的青少年进行了横断面研究。校准的检查者使用颞下颌关节紊乱研究诊断标准（RDC/TMD）评估慢性疼痛的存在和程度。为了评估社会经济状况，受试者回答了巴西经济分类标准（CCEB）问卷。使用 SPSS 中的二元逻辑回归分析数据。
结果显示，无论年龄（p = 0.153）或经济阶层（p = 0.653）如何，33.2%的受试者都有 TMD。TMD 与女性性别（p = 0.017）、过去六个月的头痛/偏头痛（p<0.001）、慢性疼痛（p<0.001）和慢性疼痛程度（p<0.001）之间存在统计学显著关联。在最终模型中，逻辑回归显示慢性疼痛程度和过去六个月的头痛/偏头痛与 TMD 的存在相关。
TMD 的患病率较高（33.2%），过去六个月有慢性疼痛和头痛的青少年更有可能患有 TMD。
这些数据有助于了解青少年的 TMD，并有助于制定预防措施和政策，以便及时发现功能障碍。
