The aim of the study was to evaluate the temporomandibular joint, the prevalence of single and multiple diagnosis and potential sided domination of temporomandibular dysfunction in patients with temporomandibular disorder-myofascial pain with referral. The study group enrolled 50 people-37 females and 13 males between 18 and 25 years old with an average age of 23.36 ± 2.14. The patients underwent joint vibration analysis. Sixty seven percent of all examined tem-poromandibular joints were classified as group I according to Mark Piper's classification. Class IIIA appeared in 17% of joints. Eight percent of temporomandibular joints were classified as class IVA. There were no statistically significant differences in the prevalence of temporomandibular disorder with respect to gender ( = 0.838639). The relatively high prevalence of multiple diagnoses proved the overlapping nature of muscle and intraarticular disorders. Twenty eight percent of the subjects suffered from a combination of myofascial pain with referral and bilateral temporoman-dibular dysfunction. In 62% of the patients a lack of intraarticular disorders was reported. The suggestion that there exists sided domination in the occurrence of temporomandibular disorders has not been confirmed. Due to the small sample size, such differences cannot be excluded. Fur-ther research is needed.
本研究旨在评估颞下颌关节、单发和多发诊断的患病率以及颞下颌关节功能紊乱-肌筋膜疼痛伴牵涉痛患者的潜在单侧支配。研究组纳入了 50 名 18-25 岁的患者，其中女性 37 名，男性 13 名，平均年龄为 23.36±2.14 岁。患者接受了关节振动分析。根据 Mark Piper 的分类，所有接受检查的颞下颌关节中有 67%被归类为 I 组。III A 类在 17%的关节中出现。4%的颞下颌关节被归类为 IV A 类。颞下颌关节紊乱的患病率与性别无关（=0.838639）。多发诊断的相对高发证明了肌肉和关节内疾病的重叠性质。28%的患者同时患有牵涉痛的肌筋膜疼痛和双侧颞下颌关节功能紊乱。62%的患者报告说没有关节内疾病。关于颞下颌关节紊乱存在单侧支配的说法尚未得到证实。由于样本量较小，不能排除这种差异。需要进一步的研究。
