Objective: To explore the relevant factors of work-related musculoskeletal disorders (WMSDs) among dentists through Meta analysis, providing a basis for the prevention and control of WMSDs among dentists. Methods: In April 2022, cross-sectional research literatures on the prevalence correlation of WMSDs among Chinese dentists were searched in databases such as China National Knowledge Infrastructure, Wanfang, VIP, PubMed, Web of Science, and Em Base database. The search was conducted from the establishment of the database until April 2022, literatures were selected using keywords such as musculoskeletal disorders and dentists. To extract gender, age, length of service, disease classification and other related influencing factors as indicator, and prevalence was selected as the outcome indicator. After evaluating the quality of the literatures, RevMan 5.3 software was used to calculate the combined RD (95%CI) values of the included literatures. Results: A total of 15 articles were included, with a total sample size of 3646 people. Meta analysis results showed that the prevalence of WMSDs among dentists in China was 80%, and the top three parts of the incidence rates were 65% of the waist, 58% of the neck, and 50% of the back. Gender, age, length of service, region and disease classification all increased the risk of WMSDs, and the combined effect size were 75%, 78%, 71%, 77% and 82% respectively (P<0.05) . Conclusion: The occurrence of WMSDs among dentists in China is related to multiple factors such as gender, age, length of service and disease classification. The above risk factors should be taken into account in the workplace and preventive measures should be actively implemented to prolong the working life of dentists.
目的： 通过Meta分析探讨口腔医生工作相关肌肉骨骼疾患（WMSDs）患病率及相关因素，为预防和控制口腔医生的WMSDs提供依据。 方法： 于2022年4月，检索中国知网、万方、维普、PubMed、Web of Science、Embase database等数据库关于我国口腔医生WMSDs患病相关性的横断面研究文献，检索时间为建库至2022年4月，以肌肉骨骼疾患、口腔医生、musculoskeletal disorders、dentist等为关键词筛选文献，提取性别、年龄、工龄、疾病分类等因素并选取患病率为结局指标；对文献质量评价后，采用RevMan 5.3软件进行Meta分析，计算纳入文献的合并效应值。 结果： 共纳入15篇文献，总样本量3 646人。Meta分析结果显示，我国口腔医生的WMSDs患病率为80%，前3位的部位为腰部（65%）、颈部（58%）、背部（50%）。性别、年龄、工龄、地域和疾病分类均可增加我国口腔医生WMSDs的患病风险，合并效应值分别为75%、78%、71%、77%、82%（P<0.05）。 结论： 我国口腔医生WMSDs的发生与性别、年龄、工龄和疾病分类等多种因素有关，在工作中应重视上述危险因素，积极实施预防措施，延长口腔医生的工作寿命。.
