This study aimed to investigate the prevalence of temporomandibular disorder (TMD) among students of the University of Jordan.
Information about the symptoms of TMD and the possible risk factors were collected using specifically designed questionnaires. The collected data sets were treated statistically using the SPSS release 14 package.
The results of the present investigation showed that pain in or about the ears or cheeks was the most prevalent symptom whereas locking of the temporomandibular joint (TMJ) was the least prevalent. Nearly one-third of the investigated sample (31.4%, 346/1103) had no symptoms of TMD whereas 68.6% (757/1103) had at least one symptom. Students of health science studies had significantly the highest risk in developing TMJ clicking compared to students studying pure science or humanitarian studies.
TMD is of a high prevalence among students of the University of Jordan, particularly among students of health and science studies, which signify the role of stress in the development and/or progression of TMD. The findings of this study are alarming and entailing further investigations to identify risk factors associated with TMD in order to establish measures for prevention and treatment.

本研究旨在调查约旦大学学生颞下颌关节紊乱病（TMD）的患病率。
使用专门设计的问卷收集有关TMD症状及可能的风险因素的信息。收集的数据集使用SPSS 14版软件进行统计学处理。
本次调查结果显示，耳部或脸颊处疼痛是最常见的症状，而颞下颌关节（TMJ）绞锁是最不常见的症状。近三分之一的被调查样本（31.4%，346/1103）没有TMD症状，而68.6%（757/1103）至少有一种症状。与纯科学或人文科学专业的学生相比，健康科学专业的学生发生TMJ弹响的风险显著更高。
TMD在约旦大学学生中患病率较高，尤其是在健康和科学专业的学生中，这表明压力在TMD发生和/或发展中的作用。本研究结果令人担忧，需要进一步调查以确定与TMD相关的风险因素，从而制定预防和治疗措施。
