Abstract

The contemporary dental unit is a masterpiece of design incorporating as many ergonomic features as possible to enable the operator, dental nurse and patient to experience the minimum of stress and fatigue. Dentists 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. Sitting in an appropriate chair, using magnification for visualization, and the selection of ergonomically-friendly equipment are essential for the health of dental clinicians. Posture varies depending on the dental stool selected. Depending on the type of magnification selected, the clinician can work with a head posture of up to 25 degrees forward. This is achieved with loupes by a set focal range. Working ergonomically helps prevent work-related injuries. Attention must be given to changing destructive postural habits and selecting equipment conducive to good posture.
