The Relation between Risk Factors and Musculoskeletal Impairment in Dental Students: a Preliminary Study

Musculoskeletal disorders are common among dentists, 80% of the measurement results using the instrument of Body Discomfort Map and Brief Survey in Faculty of Dentistry University of Indonesia (FKG UI) showed that musculoskeletal disorders (MSD) mainly occur in the neck, shoulder, forearm, hand and back. MSD are the most common type of occupational dental diseases in Indonesia. Objectives: To know the risk factors associated with MSD in students in FKG UI. Methods: This type of observational study with cross-sectional design of the entire profession students who work in clinic FKG UI. Examination of MSD was using Cornell MSD questionnaires (CMDQ) and risk factors were measured using a questionnaire with closed questions and Diagnostic Stress Survey. All data collected were analyzed statistically using chi-square test and logistic regression. Results: A significant relationship between repetitive movements of factors, awkward bending and twisting with musculoskeletal disorders (p 0.05) and the presence of a significant association between work stress factors with musculoskeletal disorders (p 0.001). Then the logistic regression results indicate that a variable effect on musculoskeletal disorders is a movement in the work (OR 5.01; CI 90%) and stress of work (OR 7.47; CI 90%). Conclusion: In this study we can conclude that the relationship between the working and movement of factors of work stress on musculoskeletal disorders.
