Abstract

Objective: Dental professionals are highly vulnerable to work-related musculoskeletal disorders (WMSD). As females, who are more prone to WMSD, represent a growing proportion of the dental workforce, this study explored sex differences in WMSD-pain prevalence among dental students, and differentiated it between preclinical and clinical students.

Methods: A multi-center cross-sectional study was conducted among dental students at three U.S. dental schools. An anonymous survey assessed prevalence of WMSD pain over the last 12 months and 7 days using the Nordic Musculoskeletal questionnaire. Sex and academic stage differences were analyzed with independent t-tests and chi-square, adjusted for demographics and occupational habits (working hours, self-reported ergonomics, loupes, sport engagement) with ANCOVA.

Results: Among 175 students (26.6±3.6 years, 66.9% females), 93.7% and 57.7% reported WMSD-pain in the past 12 months and 7 days, respectively. Females scored higher than males in pain intensity (p=.025), WMSD-pain prevalence in the past 7 days (p=.006), and number of painful body sites in the past 12 months (p=.006) and 7 days (p<.001). Clinical students had higher WMSD-pain prevalence (p<.001) and number of painful body sites (p<.001) in the past 7 days than preclinical students. Differences remained significant only among females.

Conclusion: A high prevalence of WMSD-pain was evident in dental students, with significant sex and academic stage differences.

牙科学生中与工作有关的肌肉骨骼疾病疼痛的性别和学业阶段差异。横中心横断面研究。

目的：牙科专业人员极易患与工作相关的肌肉骨骼疾病。由于女性更容易发生WMSD，在牙科劳动力中所占的比例越来越大，本研究探讨了牙科学生中WMSD疼痛患病率的性别差异，并在临床前和临床学生之间进行了区分。方法：对美国三所牙科学校的牙科学生进行多中心横断面研究。一项匿名调查使用北欧肌肉骨骼问卷评估了过去12个月零7天WMSD疼痛的患病率。用独立t检验和卡方检验分析性别和学业阶段差异，用ANCOVA对人口统计学和职业习惯（工作时间、自我报告的人体工程学、眼镜、运动参与）进行调整。结果：175名学生（26.6±3.6岁，女性占66.9%）中，93.7%和57.7%的学生报告过去12个月和7天的wmsd疼痛。在疼痛强度（p= 0.025）、近7天wmsd疼痛发生率（p= 0.006）、近12个月（p= 0.006）和近7天（ppp）疼痛部位数方面，女性得分高于男性。结论：口腔学生wmsd疼痛发生率较高，且存在显著的性别和学习阶段差异。

期刊介绍： CRANIO: The Journal of Craniomandibular & Sleep Practice is the oldest and largest journal in the world devoted to temporomandibular disorders, and now also includes articles on all aspects of sleep medicine. The Journal is multidisciplinary in its scope, with editorial board members from all areas of medicine and dentistry, including general dentists, oral surgeons, orthopaedists, radiologists, chiropractors, professors and behavioural scientists, physical therapists, acupuncturists, osteopathic and ear, nose and throat physicians. CRANIO publishes commendable works from outstanding researchers and clinicians in their respective fields. The multidisciplinary format allows individuals practicing with a TMD emphasis to stay abreast of related disciplines, as each issue presents multiple topics from overlapping areas of interest. CRANIO''s current readership (thousands) is comprised primarily of dentists; however, many physicians, physical therapists, chiropractors, osteopathic physicians and other related specialists subscribe and contribute to the Journal.
