Literature reviews have reported on the high prevalence as well as the significant burden in this specific profession.

Results: The dental workforce was predominantly female (69.7%), with mean age of 39 (SD 9.87) years and mean employment duration of 13.9 (SD 8.71) years. The most commonly reported body regions for musculoskeletal problems experienced in the past year were shoulders (61.7%), lower back (59.3%), upper back (55.7%), wrists/hands (53.4%), and neck (53.3%). Significant work-related associated factors for MSD were glare for neck (p
