Background and aims: Nowadays, work-related musculoskeletal disorders are the most common
occupational diseases. The prevention of these disorders requires a posture analysis during work
and the improvement of working conditions. The purpose of this study was to determine risk factors
for musculoskeletal disorders and corrective priorities to perform the work by conducting postures
analysis using Rapid Entire Body Assessment (REBA).
Methods: In this descriptive-analytical study, the posture of dentists during working was analyzed
using the REBA software. The incidence rate of musculoskeletal disorders was investigated by the
Nordic Musculoskeletal Questionnaire (NMQ). A P value less than 0.05 was considered statistically
Results: In this applied study, the incidence rates of the pain in neck, waist, shoulders, and wrists
were reported to be 68%, 55%, 41% and 28%, respectively. The above-mentioned values were higher
in women than in men. The pain in thigh and leg was related to work and the pain in ankle and
sole was related to body mass index (BMI). The relationship between musculoskeletal disorders and
occupational postures of dentists was statistically significant (P < 0.05).
Conclusion: Training the principles of ergonomics and anthropometrics, the correct methods and
principles of performing work, and the ways of using the instruments are necessary for the studied
population. Occupational postures require ergonomic intervention and correction.
