Abstract
Research supports that disorders from vibratory instruments are significant occupational risk factors. Vibratory instruments include the piezoelectric or magnetostrictive scaler and low or high speed handpieces. These instruments have the ability to intensify neuromuscular and musculoskeletal disorders in dental professionals. These disorders include Carpal Tunnel Syndrome, Canal of Guyon Syndrome, Rotator Cuff Tendonitis, and Brachial Plexus Compression. Dentists, hygienists, and assistants are all at risk of developing these disorders. Removing these instruments from the modern standard of health care is not an option. Vibratory instruments can have a negative impact on tactile sensitivity and nerve conduction in the ulnar, radial, and medial nerves. These disorders can lead to pain, weakness, and a decreased ability or provide optimal patient care. Stretching, ergonomics, proper positioning, and limiting the use of vibratory instrumentation can minimize this harm. Following these recommendations can delay the onset of these disorders. Future research should determine how many hours of vibratory instrumentation a clinician should undergo weekly to minimize harm. Additionally, a longitudinal study on dental professionals who soley use vibratory instruments should be conducted. Dental professionals' ability to scale, polish, and perform restorative procedures will be improved.
