Abstract
Objectives
The relationship between tinnitus and temporomandibular disorders (TMD) over the years has continued to be widely debated in literature and not yet fully understood. Several causes have been associated with tinnitus including altered mandibular posture and disorders at the muscle, joint and periodontal receptors. This study aimed to investigate masseter and temporalis muscle activity in patients with TMD with and without somatosensory tinnitus (ST).
Material and Methods
A total of 105 patients (mean age 50.49 ± 11.7 years) with TMD classified according to Axis I DC/TMD diagnostic criteria were enrolled and then divided into two groups: 53 subjects with ST and 52 without ST. Electromyographic and kinesiographic instrumental examinations were used for data collection. Statistical analyses, including Levene's test and independent t-test, were performed to evaluate and compare muscle activity abnormalities between the two groups.
Results
The study showed a higher incidence of abnormal masticatory muscle activity in habitual resting position in TMD without ST patients compared to those with TMD and ST. A statistically significant difference in muscle activity between the two groups was observed.
Conclusions
The results suggest a potential link between masticatory muscle activity and tinnitus in TMD patients. Neuroplasticity may play a role in modulating the psychoacoustic characteristics of tinnitus.
目的多年来，耳鸣与颞下颌疾病（TMD）之间的关系一直在文献中广泛争论，但尚未完全了解。与耳鸣有关的几个原因包括下颌姿势的改变和肌肉、关节和牙周受体的紊乱。本研究旨在探讨有或无躯体感觉耳鸣（ST）的TMD患者的咬肌和颞肌活动。材料与方法入选105例符合Axis I DC/TMD诊断标准的TMD患者（平均年龄50.49±11.7岁），采用肌电图和运动图仪器检查方法将患者分为两组：有ST组53例，无ST组52例。统计分析包括Levene检验和独立t检验，以评估和比较两组之间的肌肉活动异常。结果研究显示，无ST的TMD患者习惯性静息位咀嚼肌活动异常发生率高于合并ST的TMD患者，两组间肌肉活动差异有统计学意义。结论咀嚼肌活动与TMD患者耳鸣之间存在潜在联系。神经可塑性可能在调节耳鸣的心理声学特征中起作用。
期刊介绍：
Clinical and Experimental Dental Research aims to provide open access peer-reviewed publications of high scientific quality representing original clinical, diagnostic or experimental work within all disciplines and fields of oral medicine and dentistry. The scope of Clinical and Experimental Dental Research comprises original research material on the anatomy, physiology and pathology of oro-facial, oro-pharyngeal and maxillofacial tissues, and functions and dysfunctions within the stomatognathic system, and the epidemiology, aetiology, prevention, diagnosis, prognosis and therapy of diseases and conditions that have an effect on the homeostasis of the mouth, jaws, and closely associated structures, as well as the healing and regeneration and the clinical aspects of replacement of hard and soft tissues with biomaterials, and the rehabilitation of stomatognathic functions. Studies that bring new knowledge on how to advance health on the individual or public health levels, including interactions between oral and general health and ill-health are welcome.
