The purpose of the present study was to evaluate the relationship between psychological variables and the clinical diagnosis of temporomandbular disorders (TMD) in 12-year-old adolescents. TMD pain was assessed by RDC/TMD examination (Research Diagnostic Criteria for Temporomandibular Disorders) (Axis I and II). Five-hundred and fifty-eight subjects (330 girls and 228 boys) were examined. Bivariate analyses were performed using the Chi-square test (chi(2)). The logistic regression models were adjusted estimating the Odds Ratios (OR), their 95% confidence intervals (CI), and significance levels. Only 2.19% of the boys and 8.18% of the girls presented one of the Axis I categories. All variables from axis II were related to TMD diagnosis (p < 0.001). Gender was significantly related to TMD diagnosis (p = 0.0028). The risk of TMD incidence for girls was 3.5 times higher than that for boys (Odds Ratio = 3.52, Confidence Interval 1.31-9.43). The individuals who presented the variable 'characteristics of pain intensity' (CPI) higher than 0 had 31 times more risk of TMD incidence (Odds Ratio = 31.361, Confidence interval 6.01-163.5). We concluded that psychological variables and female gender are important risk indicators related to TMD incidence, even in adolescents.
本研究旨在评估心理变量与青少年颞下颌关节紊乱（TMD）临床诊断之间的关系。通过 RDC/TMD 检查（颞下颌关节紊乱的研究诊断标准）（轴 I 和 II）评估 TMD 疼痛。共检查了 558 名受试者（330 名女孩和 228 名男孩）。使用卡方检验（chi(2)）进行了双变量分析。逻辑回归模型调整了估计比值比（OR）、95%置信区间（CI）和显著性水平。只有 2.19%的男孩和 8.18%的女孩出现了轴 I 类别的一种。轴 II 中的所有变量都与 TMD 诊断相关（p < 0.001）。性别与 TMD 诊断显著相关（p = 0.0028）。女孩发生 TMD 的风险是男孩的 3.5 倍（OR = 3.52，95%CI 1.31-9.43）。疼痛强度特征变量（CPI）大于 0 的个体发生 TMD 的风险增加 31 倍（OR = 31.361，95%CI 6.01-163.5）。我们得出结论，心理变量和女性性别是与 TMD 发生率相关的重要风险指标，即使在青少年中也是如此。
