Even though singing is regarded as potential jaw-overuse behaviour, the actual evidence that underlines the idea of singing as a predisposing factor for pain-related temporomandibular disorders (TMD) is very limited.
The objectives were to examine if a dose-response relationship exists between the frequency of singing and TMD pain intensity, and if singing is associated with psychological well-being.
The records of 1467 adult patients with functionally aggravated TMD pain were examined. Partial Spearman correlations were used to explore for associations between singing frequency and Characteristic Pain Intensity (CPI), somatic symptoms, depression and anxiety.
The mean age of all participants was 42.8 years (±15.3), of which 79.2% were female. Contrary to the male-female ratio, no difference was found in the mean age between the response options with regard to the frequency of singing. Controlled for the influence of gender, the Spearman correlation between the frequency of singing and CPI appeared to be significant and indicated a negative association. In addition, somatic symptoms appeared to be positively associated with the frequency of singing. However, the observed correlation coefficients (ρ = -.073 and ρ = .067, respectively) imply that these are only very weak or negligible correlations. No significant associations with the frequency of singing were found for depression and anxiety.
The alleged negative influence of singing on TMD pain intensity was found to be virtually absent. Patients with TMD pain who sing frequently have almost equal scores on psychological well-being compared to those who sing less.
尽管唱歌被认为是潜在的下颌过度使用行为，但实际上并没有充分的证据表明唱歌是引发与颞下颌关节紊乱（TMD）相关疼痛的一个因素。
本研究旨在探讨唱歌频率与 TMD 疼痛强度之间是否存在剂量反应关系，以及唱歌是否与心理健康有关。
对 1467 名因功能障碍加重而出现 TMD 疼痛的成年患者的记录进行了检查。采用部分 Spearman 相关分析来探讨唱歌频率与特征疼痛强度（CPI）、躯体症状、抑郁和焦虑之间的相关性。
所有参与者的平均年龄为 42.8±15.3 岁，其中 79.2%为女性。与男女比例相反，在唱歌频率的反应选项中，年龄的平均值之间没有差异。控制性别影响后，唱歌频率与 CPI 之间的 Spearman 相关似乎具有统计学意义，表明存在负相关。此外，躯体症状与唱歌频率呈正相关。然而，观察到的相关系数（ρ分别为-0.073 和 0.067）表明，这些相关性非常微弱或可以忽略不计。唱歌频率与抑郁和焦虑之间没有显著关联。
唱歌对 TMD 疼痛强度的所谓负面影响实际上几乎不存在。与唱歌较少的 TMD 疼痛患者相比，频繁唱歌的患者在心理健康方面的得分几乎相同。
