Dentists are exposed to a wide range of work-related factors that may result in various occupational diseases of which musculoskeletal disorders (MSDs) are common. The purpose of this study was to determine the prevalence and distribution of MSDs among dental professionals of our institution and to compare the prevalence of MSDs among the various dental specialists.
A self-administered questionnaire, which included basic demographic details, work experience in dentistry, and work profile related questions along with the Standard Nordic Questionnaire, was administered to the study participants. Statistical analysis for the data obtained was performed using SPSS Version 16.0 (Chicago, SPSS Inc.). The chi-square test was applied to test the association between MSD and variables such as gender, designation, type of dentistry and usage of computers. The Mann Whitney U test was used to assess the relationship between MSD and age, experience, sick leave, number of patients attended per day. A p-value < 0.05 was considered significant.
151 subjects participated in the study, and the prevalence of MSD in the last 12 months among dental professionals was 58.3% (88 out of 151 subjects). The most common site affected by MSD was the neck (66.7%). Also, it was noted that among various dental specialists, the Endodontists suffered the maximum (88.02%) musculoskeletal pain. Fifty individuals (33.11%) suffered from pain in multiple sites.
Work-related musculoskeletal disorders and pain can be reduced through proper operator-patient positioning, taking adequate breaks between patients, maintaining good physical health through regular exercises.
牙医会接触到各种各样与工作相关的因素，这些因素可能导致各种职业病，其中肌肉骨骼疾病（MSDs）较为常见。本研究的目的是确定我院牙科专业人员中肌肉骨骼疾病的患病率和分布情况，并比较不同牙科专科医生中肌肉骨骼疾病的患病率。
向研究参与者发放一份自填式问卷，其中包括基本人口统计学细节、牙科工作经验、与工作概况相关的问题以及标准北欧问卷。使用SPSS 16.0版（芝加哥，SPSS公司）对获得的数据进行统计分析。应用卡方检验来检验肌肉骨骼疾病与性别、职称、牙科类型和计算机使用等变量之间的关联。使用曼-惠特尼U检验来评估肌肉骨骼疾病与年龄、经验、病假、每天接待患者数量之间的关系。p值<0.05被认为具有统计学意义。
151名受试者参与了本研究，牙科专业人员在过去12个月中肌肉骨骼疾病的患病率为58.3%（151名受试者中有88名）。受肌肉骨骼疾病影响最常见的部位是颈部（66.7%）。此外，还注意到在不同的牙科专科医生中，牙髓病医生遭受肌肉骨骼疼痛的比例最高（88.02%）。50人（33.11%）在多个部位疼痛。
通过正确的医患体位摆放、在患者之间适当休息、通过定期锻炼保持良好的身体健康，可以减少与工作相关的肌肉骨骼疾病和疼痛。
