Musculoskeletal disorders and risk indicators for pain chronification among German dentists A cross-sectional questionnaire-based study

Objectives. The aim of this study was to determine the prevalence of musculoskeletal (MS) disorders in practicing German dentists and identify risk factors for pain chronification. Methods. This was a cross-sectional, quantitative, questionnaire-based study in which the validated German version of the & Ouml;rebro Musculoskeletal Pain Questionnaire was sent out to practicing German dentists. Results. Of the 8,072 questionnaires sent out, 576 dentists responded (60.2% men, 39.8% women; mean [SD] age, 50 [10.1] years; response rate, 7.1%). Overall, 344 dentists had current pain at 719 pain sites (point prevalence, 59.7%). The risk of chronic pain in dentists with current MS pain was high in 28.5% (n = 98), moderate in 30.5% (n = 105), and low in 41% (n = 141). The multivariate logistic regression analysis showed that specialization in restorative dentistry was associated with a significantly higher risk of experiencing pain chronification (odds ratio [OR], 3.94; P = .008), followed by specialization in pediatric dentistry (OR, 0.35; P = .048). A history of current pain, particularly current leg pain, was predictive of higher chronification risk (OR, 22.0; P < .001) and neck pain (OR, 4.51; P = .001). Conclusions. Almost two-thirds of practicing German dentists have MS pain, and one-third of these have a moderate through high risk of developing pain chronification. These health problems have an adverse impact on their ability to successfully perform dental services, with the potential for prolonged sick leave, disability, and early retirement. Accordingly, these problems deserve greater attention from the scientific community (identification of risk factors), universities (sensitization and education), and policy makers (development and implementation of appropriate countermeasures for MS disorders in the dental profession). Practical Implications. Knowing the risk factors associated with acute and chronic MS pain may help dentists take preventive measures and thereby improve their physical well-being and workrelated quality of life.
