Among the wide range of musculoskeletal disorders, back pain was the most common among dentists, followed by neck pain, high muscle tension on the trapezoids, tendinitis, carpel tunnel syndrome, nerve trapping, early arthrosis, myopia, and auditive alterations [5].
Pargali and Jowkar [6] in 2010 reported that 73% of dentists complained of back and neck pain. Even though the practice of fourhanded dentistry and the use of ergonomically well-adjusted equipment are on the rise, literature reports have reported a rise in back, neck, shoulder, and arm pain, in almost 81% of dental professionals [6].
Work-related stress, tension, and awkward postural positions can add to back and neck problems for the dentist [7e11].
There is always a neutral zone of movement for every joint and muscle. Injury risks increase whenever work requires a person to perform tasks with body segments outside of his or her neutral range in a deviated posture [12].
