An Ounce of Prevention is Worth a Pound of Cure: Ergonomics in Dental Practice

Dentists and dental hygienists are at risk for work-related musculoskeletal disorders compared to the general population. The most frequent injuries occur in the spine (neck and back), shoulders, elbows and hands. While specific procedures place the clinician at increased risk for finger and hand injuries, poor posture is a risk factor with all procedures. Sitting in an appropriate chair, using magnification for visualization, and the selection of ergonomically-friendly equipment are essential for the health of dental clinicians. Ergonomics is the science of designing jobs, equipment and workplaces to fit workers. Proper ergonomics design is necessary to prevent repetitive strain injuries, which can develop over time and can lead to long term disability. This article includes musculoskeletal disorders (MSDs) and the signs, symptoms and risk factors of these types of injuries, so that one can be aware of developing problems and can change his /her approach to work or alter the workstation setup to prevent further injury. The article discusses the applications of ergonomics in dental clinic set up and offers different exercises to work with comfort, efficiency and ease.
