Background: Temporomandibular disorders are craniofacial disorders characterized by the presence of chronic pain in masticatory muscles, with higher incidence in the women population. There is little research that has studied tongue force related to temporomandibular disorders, but there are a lot of studies that have demonstrated the impact of tongue force in vital functions, such as chewing, swallowing, phonation, or breathing. According to this, the aim of this study was to compare the maximum force of the tongue between females with chronic temporomandibular disorders and asymptomatic females. We also wanted to establish whether any relationship existed between the pain and fatigue versus the maximum force developed in females with chronic temporomandibular disorders. Material and methods: A cross-sectional study of 67 women between the ages of 18 and 65 years old was performed. The included women were assigned to one of two groups, according to whether they had chronic temporomandibular disorders or not. The procedure was the same for both groups. Outcome measures included the maximum tongue force, intensity of perceived orofacial pain, and intensity of perceived orofacial fatigue. Results: The results showed significant statistical differences for the maximum tongue force measurement between the chronic temporomandibular disorders group and the control group (p < 0.05) for all the movements, except the lip pressure measurement. Furthermore, the analysis revealed significant statistical differences between the intensity of perceived orofacial fatigue between the groups (p < 0.05). Moreover, the data showed no significant correlations between variables. Conclusion: The study found significant differences in maximum tongue force when comparing women with chronic temporomandibular disorders and asymptomatic women (being superior in these). Likewise, we found that the intensity of perceived orofacial fatigue after tongue exercises showed significant differences between groups. However, this study reveals no correlations between the intensity of perceived orofacial pain and fatigue and the maximum tongue force.
颞下颌关节紊乱病是一种颅面部疾病，其特征为咀嚼肌存在慢性疼痛，在女性群体中的发病率较高。关于与颞下颌关节紊乱病相关的舌力的研究较少，但有许多研究已经证明了舌力在诸如咀嚼、吞咽、发声或呼吸等重要功能中的作用。据此，本研究的目的是比较患有慢性颞下颌关节紊乱病的女性与无症状女性之间的最大舌力。我们还想确定在患有慢性颞下颌关节紊乱病的女性中，疼痛和疲劳与最大舌力之间是否存在任何关系。
对67名年龄在18至65岁之间的女性进行了一项横断面研究。根据是否患有慢性颞下颌关节紊乱病，将纳入的女性分为两组之一。两组的程序相同。观察指标包括最大舌力、口腔面部疼痛感知强度和口腔面部疲劳感知强度。
结果显示，除唇压测量外，慢性颞下颌关节紊乱病组和对照组在所有运动的最大舌力测量上均存在显著统计学差异（p < 0.05）。此外，分析显示两组之间在口腔面部疲劳感知强度上存在显著统计学差异（p < 0.05）。而且，数据显示各变量之间无显著相关性。
该研究发现，比较患有慢性颞下颌关节紊乱病的女性和无症状女性时，最大舌力存在显著差异（前者更大）。同样，我们发现舌部运动后口腔面部疲劳感知强度在两组之间存在显著差异。然而，本研究表明口腔面部疼痛和疲劳感知强度与最大舌力之间无相关性。
