Abstract

Background

Previous studies have focused on alleviating pain in patients with temporomandibular disorders (TMDs). However, deficits in masticatory function, including subjective eating experience and masticatory performance, and the associations between pain and mastication have not been fully elucidated.

Objective

The current study aimed to investigate clinical pain, masticatory function, and their associations in patients with muscular TMD before and after treatment.

Methods

Twenty-seven patients with muscular TMD and 27 healthy participants (non-TMD group) were included. The groups were matched based on age, sex, and number of missing teeth. The TMD group completed assessments at two timepoints: the first time when they underwent TMD examinations, and 3 months later. All the participants underwent assessments of masticatory function, including subjective experiences of eating difficulty in daily meals and the use of adaptive eating strategies, as well as an objective assessment of masticatory performance. Additionally, current pain and muscle pain were assessed among TMD patients before and after treatment.

Results

(a) Before treatment, patients with muscular TMD had greater eating difficulty and used more adaptive eating strategies than non-TMD individuals but exhibited similar masticatory performance. (b) Patients with muscular TMD had improved masticatory performance, reduced current pain, and reduced muscle pain after treatment. (c) Before treatment, more severe pain was associated with worse masticatory performance among TMD patients. The association between muscle pain and masticatory performance was nonsignificant.

Conclusion

Patients with muscular TMD had worse masticatory experience than individuals without TMD but maintained adequate masticatory performance. Treatment was associated with improved masticatory performance, and more severe pain before treatment was associated with worse masticatory performance.

肌肉性颞下颌疾病患者疼痛与咀嚼功能的复杂关系。

背景：以往的研究主要集中在减轻颞下颌疾病（TMDs）患者的疼痛。然而，咀嚼功能的缺陷，包括主观进食体验和咀嚼表现，以及疼痛和咀嚼之间的关系尚未完全阐明。目的：本研究旨在探讨肌肉性TMD患者治疗前后的临床疼痛、咀嚼功能及其相关性。方法：选取27例肌肉性TMD患者和27例健康受试者（非TMD组）。各组根据年龄、性别和缺牙数量进行匹配。TMD组在两个时间点完成评估：第一次接受TMD检查时和3个月后。所有参与者都接受了咀嚼功能的评估，包括日常饮食中进食困难的主观体验和适应性饮食策略的使用，以及咀嚼表现的客观评估。此外，评估治疗前后TMD患者的当前疼痛和肌肉疼痛。结果：(a)治疗前，肌肉性TMD患者比非TMD患者有更大的进食困难，使用更多的适应性进食策略，但咀嚼表现相似。(b)肌性TMD患者在治疗后咀嚼功能改善，当前疼痛减轻，肌肉疼痛减轻。(c)治疗前，TMD患者疼痛程度越严重，咀嚼功能越差。肌肉疼痛与咀嚼功能之间的关联不显著。结论：肌性TMD患者的咀嚼体验比非肌性TMD患者差，但仍能保持良好的咀嚼功能。治疗与咀嚼功能的改善有关，治疗前更严重的疼痛与咀嚼功能更差有关。

期刊介绍： Journal of Oral Rehabilitation aims to be the most prestigious journal of dental research within all aspects of oral rehabilitation and applied oral physiology. It covers all diagnostic and clinical management aspects necessary to re-establish a subjective and objective harmonious oral function. Oral rehabilitation may become necessary as a result of developmental or acquired disturbances in the orofacial region, orofacial traumas, or a variety of dental and oral diseases (primarily dental caries and periodontal diseases) and orofacial pain conditions. As such, oral rehabilitation in the twenty-first century is a matter of skilful diagnosis and minimal, appropriate intervention, the nature of which is intimately linked to a profound knowledge of oral physiology, oral biology, and dental and oral pathology. The scientific content of the journal therefore strives to reflect the best of evidence-based clinical dentistry. Modern clinical management should be based on solid scientific evidence gathered about diagnostic procedures and the properties and efficacy of the chosen intervention (e.g. material science, biological, toxicological, pharmacological or psychological aspects). The content of the journal also reflects documentation of the possible side-effects of rehabilitation, and includes prognostic perspectives of the treatment modalities chosen.
