The aim of the current investigation was to study the prevalence of temporomandibular disorder (TMD) among university students of North Saudi Arabia.
A specifically constructed questionnaire was distributed to 489 university students to investigate the prevalence of temporomandibular joint (TMJ) findings among them. The study sample consisted of 346 males and 143 females (age range was 18-25 years). The data were analyzed, and probability values were set at p ≤ 0.05.
A total of 49.7% of participants had at least one sign or symptom of TMD. Clicking was the most reported finding. Pain in or about the ears/cheeks was the second most common finding. In all, 24.3% of the participants reported one TMJ finding; meanwhile, 0.4% reported the presence of five concurrent TMJ signs and symptoms. Females reported more TMJ signs and symptoms than males (p < 0.05). Science and health students reported more TMD findings than humanitarian college students (p < 0.05).
University students in north Saudi Arabia reported high prevalence of TMD. Also, students from science and health colleges reported higher prevalence of TMD findings than humanitarian college students. Clicking and pain are the most prevalent findings of TMD among university students. The results of this investigation highlight the need for additional research to shed more light on the risk factors and findings related to TMD. This will facilitate drawing adequate guidelines for prevention and management of TMD.
本次调查旨在研究沙特阿拉伯北部大学生颞下颌关节紊乱病（TMD）的患病率。
向489名大学生发放一份专门设计的问卷，以调查他们颞下颌关节（TMJ）相关表现的患病率。研究样本包括346名男性和143名女性（年龄范围为18 - 25岁）。对数据进行分析，将概率值设定为p≤0.05。
共有49.7%的参与者至少有一项TMD的体征或症状。弹响是报告最多的表现。耳部/脸颊疼痛或周围疼痛是第二常见的表现。总体而言，24.3%的参与者报告有一项TMJ相关表现；同时，0.4%的参与者报告有五项TMJ并发体征和症状。女性报告的TMJ体征和症状比男性更多（p < 0.05）。理工科和医科专业学生报告的TMD相关表现比人文学院学生更多（p < 0.05）。
沙特阿拉伯北部的大学生报告TMD患病率较高。此外，理工科和医科专业的学生报告的TMD相关表现患病率高于人文学院学生。弹响和疼痛是大学生中TMD最常见的表现。本次调查结果凸显了开展更多研究以进一步阐明与TMD相关的风险因素和表现的必要性。这将有助于制定关于TMD预防和管理的适当指南。
