Reducing the risks for musculoskeletal disorders among oral health professionals

Prolonged muscle strain and repetitive movements may lead to work-related musculoskeletal disorders (WMSDs) in oral healthcare professionals. Studies show 54% to 93% of oral healthcare professionals experience work-related pain, and approximately 68% experience pain in the neck, lower back, and shoulders. Over time, the gradual severity of WMSDs may lead to increased physical limitations and the inability to work.

This study aimed to determine whether feedback involving photography and self-assessments would improve the postures and the accuracy of ergonomic self-assessment among practicing dentists and dental hygienists.


Ergonomics training utilizing photography and feedback resulted in improvements in both ergonomic scores and the accuracy of ergonomic self-assessments among practicing dentists and dental hygienists. All participants strongly agreed it was essential to understand and properly apply ergonomics, and to develop accurate ergonomic self-assessment skills for clinical practice.


Improving self-awareness for ergonomics through self-assessment can help reduce the risk of developing WMSDs among practicing dentists and dental hygienists.
