0390 Musculoskeletal Complaints Among Dental Practitioners
2012年对965名牙科从业者的调查显示，76%的人在工作日期间或结束后经常出现疼痛、麻木等症状，背部和手部症状最常见，且与专业领域、从业年限及工作设备相关。
<h3>Objectives</h3> To describe the prevalence and risk factors of musculoskeletal disorders among dental practitioners. <h3>Method</h3> In 2012, 965 dental practitioners attending the American Dental Association Annual Session filled out surveys on individual characteristics and symptoms, then were clinically examined using the McKenzie evaluation method. Chi-square tests and linear regression were used to statistically compare associations between dental practitioner characteristics with musculoskeletal complaints. <h3>Results</h3> 76.0% of practitioners regularly experienced pain, tingling, or numbness in their fingers, wrists, hands, forearms, shoulders, neck, back and chest during or at the end of a workday. Repetitive action during work was the most commonly reported origin of symptoms, reported in 37.9% of cases. 68.3% of practitioners reported that symptoms had prevented them from working. Symptoms located in the back were the most common, reported by 51.2%. Location of symptoms was not related to gender, dominant hand, or age, but was related to specialty: dental hygienists and endodontists had significantly higher rates of back and hand symptoms than those in other dental fields (Chi-square p-values: 0.02, 0.002). Years spent in practice was a significant predictor of the degree of symptoms (all F-test p-values <0.05). Equipment used during the workday affected complaints: magnifier use was associated with increased musculoskeletal symptoms, as were different operator chair types. Other significant predictors were exercising or stretching during the workday and self-reported working posture (Chi-square p-values: 0.002, 0.002). <h3>Conclusions</h3> The dental profession experiences a high rate of musculoskeletal complaints. Ergonomic and educational interventions can prevent musculoskeletal complaints, and are clearly necessary for dental practitioners.
