Due to a permanent and excessive overload of axial (cervical and lumbar spine segments) as well as peripheral joints (especially hand and shoulder), dentists usually present with significant burden of professional-related musculoskeletal issues. The aim of our study was to describe work-related cervical spine complains and to perform an electromyographic (EMG) analysis of cervical muscles during specific working activities in dentists. Cross-sectional 24-weeks study including 30 dentists and primary care physicians. Each participant in both groups was asked to complete a specific questionnaire derived from Cornell Musculoskeletal Discomfort Questionnaire that included: general data, clinical parameters (signs and symptoms of cervical spine involvement), data on occupational activity (working position prevailing during work, use of magnifying devices such as glass, microscope) and extra-professional. As a second step after completion of the above mentioned questionnaire, all subjects performed an EMG test. The muscles involved in the static and dynamic of the cervical spine e.g. splenius capitis and trapezium were examined with the help of a surface electrodiometer. Specific work overload in dentistry, prolonged vicious position of the head and cervical segment, asymmetric contraction of the posterior musculature of the spine, adverse static positions, permanent focused vision in a limited space, vibrating tools essentially contribute to musculoskeletal issues, particularly in the cervical spine.
