Ergonomics in the Dental Practice: Preventing Disorders

Why musculoskeletal disorders are a concrete occupational risk for dentists and hygienists, and the FDI World Dental Federation's practical guidance for correct posture at the dental unit.

Dental practice imposes static, prolonged, often unnatural postures on the body: repeatedly leaning over the patient, keeping neck and back flexed for hours, and performing fine, repetitive movements with hands and wrists are all conditions that, accumulated over time, make musculoskeletal disorders one of the most concrete and underestimated occupational risks in the profession. The most common conditions among professionals in the field include low back pain, neck pain, carpal tunnel syndrome and tendinitis of the shoulders and arms — conditions that, if neglected, can seriously compromise professional longevity.

The FDI World Dental Federation has published practical guidelines on ergonomics and correct posture during treatment, as part of a broader project dedicated to health and safety in the dental workplace. The underlying principle is that ergonomics shouldn't be treated as a secondary detail, but as a direct investment in the practice's long-term health and productivity: a professional working with correct posture is more focused, makes fewer errors and can sustain longer working hours without excessive fatigue.

Practically, the most relevant recommendations include: keeping the back as aligned as possible, avoiding prolonged torso twisting toward the patient; alternating, where possible, between sitting and standing during the workday; using magnification systems (loupes or an operating microscope) that, beyond the direct clinical benefit, allow working at a greater working distance, reducing the need to bend excessively over the patient; and ensuring good lighting of the operative field to avoid compensatory neck movements caused by poor visibility.

Practice equipment also plays a direct role: operator chairs and ergonomic stools, designed to support the spine's natural curvature during long working hours, aren't simply furniture but genuine prevention tools. A well-designed dental unit, with instruments positioned to reduce unnatural torso and neck movements, directly helps reduce cumulative fatigue over the course of the day and the career.
