Musculoskeletal disorders (MSDs) are injuries to the musculoskeletal (MSK) system that occur due to repetitive or singular trauma and negatively affect one's daily life. Dentistry is a field that exposes professionals to the highest rate of work-related MSDs. This study aimed to assess the prevalence and predictors of MSK pain among a sample of dental students.
A cross-sectional study was conducted among a sample of 377 dental students and interns at the dental school of King Abdulaziz University, Jeddah, Saudi Arabia. We distributed a validated questionnaire, the Nordic Back Pain Questionnaire, which included additional questions, to all dental students participating in clinical practice and to dental interns. Categorical variables were described by presenting frequencies and percentages, and continuous variables by displaying means and standard deviations. Logistic regression was performed to identify predictors for developing MSK pain over the last 12 months.
Overall, 91.2% of the participants experienced MSK pain or discomfort in one or more body parts over the last 12 months. The highest prevalence was for neck pain (69.2%), followed by shoulder pain (67.1%) and lower back pain (65%). Females were more likely than males to experience MSK pain (odds ratio [OR] = 2.98, 95% confidence interval [CI]: 1.3-6.7), and those who exercised regularly were less likely to experience MSK pain than were those who did not (OR = 0.27, 95% CI: 0.1-0.6).
This study showed a concerningly high prevalence of MSD symptoms among dental students, especially in the neck, shoulders, and lower back. Educational and occupational health programs in preclinical years could be effective for reducing MSK pain.
肌肉骨骼疾病（MSDs）是由于重复性或单次创伤导致的肌肉骨骼（MSK）系统损伤，会对个人日常生活产生负面影响。牙科领域使专业人员面临与工作相关的肌肉骨骼疾病的发生率最高。本研究旨在评估牙科学生样本中肌肉骨骼疼痛的患病率及预测因素。
在沙特阿拉伯吉达阿卜杜勒阿齐兹国王大学牙科学院的377名牙科学生和实习生样本中进行了一项横断面研究。我们向所有参与临床实践的牙科学生和牙科实习生发放了一份经过验证的问卷，即北欧背痛问卷，该问卷还包括其他问题。分类变量通过呈现频率和百分比来描述，连续变量通过显示均值和标准差来描述。进行逻辑回归以确定过去12个月内发生肌肉骨骼疼痛的预测因素。
总体而言，91.2%的参与者在过去12个月内经历过一个或多个身体部位的肌肉骨骼疼痛或不适。患病率最高的是颈部疼痛（69.2%），其次是肩部疼痛（67.1%）和下背部疼痛（65%）。女性比男性更有可能经历肌肉骨骼疼痛（优势比[OR]=2.98，95%置信区间[CI]：1.3 - 6.7），并且经常锻炼的人比不锻炼的人经历肌肉骨骼疼痛的可能性更小（OR = 0.27，95% CI：0.1 - 0.6）。
本研究表明牙科学生中肌肉骨骼疾病症状的患病率高得令人担忧，尤其是在颈部、肩部和下背部。临床前几年的教育和职业健康计划可能对减轻肌肉骨骼疼痛有效。
