Abstract：
OBJECTIVE: Temporomandibular disorders (TMD) affect individuals undergoing increased stress, for example, dental professionals. No study to date has compared dental students and faculty in TMD manifestation. This cross-sectional study compared prevalence, risk factors, and impact on daily activities of self-reported TMD signs/symptoms between dental students and faculty at a predoctoral dental school, and between preclinical (first- to second-year) and clinical (third- to fourth-year) students.
METHODS: A REDCap survey was sent to dental students and faculty, assessing TMD signs/symptoms (TMD Symptom Questionnaire), pain intensity (Chronic Graded Pain Scale), jaw function (Jaw Function Limitation Scale), parafunctions (Oral Behavioral Checklist), previous TMD treatments, anxiety/depression symptoms (Patient Health Questionnaire), perceived stress (Perceived Stress Scale), and sleep quality (RU-SATED Scale). Outcomes were compared between groups using chi-square and t-tests, adjusting for covariates with analyses of covariance (ANCOVA).
RESULTS: Data derived from N = 145 participants (N = 108 students, N = 37 faculty). Dental students reported significantly higher prevalence (90.1% vs. 75.7%, p = 0.020) and greater number of TMD signs/symptoms (5.3 ± 3.5 vs. 3.0 ± 2.7, p < 0.001) compared to faculty. Students reported significantly more parafunctional activities (p = 0.000), jaw-strain episodes (prolonged mouth opening, p = 0.007), higher stress level (p = 0.008), and lower sleep quality (p = 0.002) than faculty. Difference in number of TMD signs/symptoms was maintained after adjusting for stress, sleep quality, and parafunctional/jaw-strain activities. Clinical students utilized significantly more often evidence-based TMD treatment compared to preclinical students.
CONCLUSIONS: High prevalence of self-reported TMD was observed among dental students and faculty, with students reporting higher prevalence and impairment despite working in the same environment. Findings underscore the importance of education on preventive measures early in dental training to address contributing factors and TMD management.

摘要：
目的：颞下颌关节紊乱病（TMD）影响压力增加的个体，例如,牙科专业人士。到目前为止，还没有研究比较牙科学生和教师的TMD表现。这项横断面研究比较了患病率，危险因素，和影响自我报告的TMD体征/症状的日常活动之间的牙科学生和教师在一个博士前的牙科学校，以及临床前（一年级至二年级）和临床（三年级至四年级）学生之间。
方法：向牙科学生和教师发送了REDCap调查，评估TMD体征/症状（TMD症状问卷），疼痛强度（慢性等级疼痛量表），颌骨功能（颌骨功能限制量表），辅助功能（口头行为清单），以前的TMD治疗，焦虑/抑郁症状（患者健康问卷），感知压力(感知压力量表)，和睡眠质量（RU-SATED量表）。使用卡方检验和t检验比较两组之间的结果，用协方差分析(ANCOVA)调整协变量。
结果：数据来自N=145名参与者（N=108名学生，N=37教员）。牙科学生报告的患病率明显更高（90.1%vs.75.7%,p=0.020）和更多的TMD体征/症状（5.3±3.5vs.3.0±2.7，p<0.001）与教师相比。学生报告的超功能活动明显增多（p=0.000），下颌拉伤发作（长时间张嘴，p=0.007),较高的应力水平（p=0.008），睡眠质量(p=0.002)低于教师。在调整压力后，TMD体征/症状的数量差异得以维持，睡眠质量,和超功能/下颌应变活动。与临床前学生相比，临床学生使用基于证据的TMD治疗的频率明显更高。
结论：在牙科学生和教职员工中观察到自我报告的TMD患病率很高，尽管在相同的环境中工作，但学生报告的患病率和损害较高。研究结果强调了在牙科培训中早期进行预防措施教育以解决影响因素和TMD管理的重要性。
