Temporomandibular joint disorders (TMDs) affect the temporomandibular joint and associated structures of the stomatognathic system. Joint Vibration Analysis (JVA) is a non-invasive method used to assess TMJ dysfunction through vibration frequencies. This study aimed to explore how age and gender influence TMJ vibration characteristics, hypothesizing that these factors may affect diagnostic accuracy in TMJ evaluations. : This cross-sectional study includes 251 participants (143 females and 108 males) aged 10 to 30 years. TMJ evaluation used JVA to assess range of motion, integral values, and frequency distributions over and under 300 Hz. Participants with a history of TMJ disorders or significant maxillofacial trauma were excluded. Statistical analysis was conducted using employing Kolmogorov-Smirnov tests for data distribution, Kruskal-Wallis test for group comparisons, and Pearson correlation test for variable relationships. : Significant gender differences in range of motion (ROM) were observed, with males exhibiting higher values ( = 0.005). Age notably influenced vibration frequencies, particularly in total integral values (TIL and TIR) and frequency distributions around 300 Hz, suggesting links to degenerative changes. Females showed more pronounced age-related effects on vibration parameters. However, gender did not greatly affect vibration characteristics across all frequency bands, indicating that other factors also impact TMJ function. : Age and gender significantly influence TMJ vibrations and the interpretation of JVA in clinical settings. Personalized approaches considering these demographic factors may enhance the accuracy of TMJ dysfunction diagnoses.
颞下颌关节紊乱病（TMDs）会影响颞下颌关节及口颌系统的相关结构。关节振动分析（JVA）是一种通过振动频率来评估颞下颌关节功能障碍的非侵入性方法。本研究旨在探讨年龄和性别如何影响颞下颌关节的振动特征，并假设这些因素可能会影响颞下颌关节评估中的诊断准确性。：这项横断面研究纳入了251名年龄在10至30岁之间的参与者（143名女性和108名男性）。颞下颌关节评估采用JVA来评估运动范围、积分值以及300Hz上下的频率分布。有颞下颌关节紊乱病史或严重颌面外伤史的参与者被排除。采用Kolmogorov-Smirnov检验进行数据分布分析，Kruskal-Wallis检验进行组间比较，Pearson相关检验进行变量关系分析。：观察到运动范围（ROM）存在显著的性别差异，男性的值更高（ = 0.005）。年龄对振动频率有显著影响，特别是在总积分值（TIL和TIR）以及300Hz左右的频率分布方面，这表明与退行性变化有关。女性在振动参数上表现出更明显与年龄相关的影响。然而，性别在所有频段对振动特征的影响不大，这表明其他因素也会影响颞下颌关节功能。：年龄和性别在临床环境中对颞下颌关节振动及JVA的解读有显著影响。考虑这些人口统计学因素的个性化方法可能会提高颞下颌关节功能障碍诊断的准确性。
