This study determined the prevalence of signs and symptoms of temporomandibular joint dysfunction (TMD) in children with and without generalized joint hypermobility (GJH). Twenty children with GJH, ages 4-19, and 20 age- and sex-matched control children completed a TMD signs/symptoms history and underwent an examination consisting of palpation of the joints and associated musculature for tenderness, clicking, or crepitation. Children with historical or clinical findings were designated positive for TMD signs/symptoms. Maximum vertical opening, expressed as a percentage of lower facial height, and maximum mandibular lateral excursion (in mm) were recorded. Fifteen (75%) of the GJH participants and ten (50%) of the controls were positive for TMD findings. There were statistically significant differences between the groups for the presence of total positive findings (P < 0.001) and for responses to palpation of muscle or joint (P = 0.03). There were no significant differences in positive responses to the history alone, joint palpation alone, or muscle palpation alone. There were no significant differences between the groups in jaw excursions. This study suggests that children with GJH may be more likely to demonstrate some signs and symptoms of TMD than children with normal joint mobility.
本研究确定了患有和未患有全身关节过度活动（GJH）的儿童颞下颌关节紊乱（TMD）体征和症状的患病率。20名年龄在4至19岁之间患有GJH的儿童以及20名年龄和性别匹配的对照儿童完成了TMD体征/症状病史调查，并接受了一项检查，包括触诊关节及相关肌肉组织，以检查压痛、弹响或摩擦音。有病史或临床检查结果的儿童被认定为TMD体征/症状呈阳性。记录最大垂直开口度（以下面部高度的百分比表示）和最大下颌侧方运动度（以毫米为单位）。GJH组中有15名（75%）参与者TMD检查结果呈阳性，对照组中有10名（50%）呈阳性。两组在总阳性结果的存在情况（P < 0.001）以及肌肉或关节触诊反应（P = 0.03）方面存在统计学显著差异。仅对病史、仅对关节触诊或仅对肌肉触诊的阳性反应没有显著差异。两组在颌运动度方面没有显著差异。本研究表明，与关节活动正常的儿童相比，患有GJH的儿童可能更有可能表现出一些TMD的体征和症状。
