Objectives: The purpose of this study was to estimate the prevalence of musculoskeletal symptoms and work-related factors of these symptoms in dental hygienists.
Methods: This questionnaire survey was conducted during May to August 2010 with 269 dental hygienists recruited as study subjects. The presence of musculoskeletal symptoms was assessed using a questionnaire of musculoskeletal symptoms from the Korea Occupational Safety Health Agency and work-related factors, and consisted of 7 job environmental factors and 4 job positions. Data analysis was performed using the chi square test and multiple logistic regression analysis using the SAS (ver 9.1) software.
Results: The overall prevalence of musculoskeletal symptoms was 86.30% (233/269). The specific prevalence of musculoskeletal symptoms for different regions of the body were as follows: 64.44% in shoulders, 51.48% in legs/feet, 48.15% in waist, 47.41% in neck, 43.33% in hands/wrists/fingers, and 17.78% in arms/elbows. The related factors of musculoskeletal symptoms in dental hygienists were type of work place (OR=2.86, 95% CI: 1.07∼7.65 in dental clinics; reference group-dental hospital), number of patients per day (OR=6.10, 95% CI: 1.06∼35.04 in 15∼19 patients per day; reference group-below 10 patients per day), subjective physical burden (OR=3.06, 95% CI: 1.18∼7.94 in presence of physical burden; reference group-absence of physical burden) and location of operation (OR=9.60, 95% CI: 1.80∼51.19 in back to side position; reference group front to side position).
Conclusions: More than four-fifths of the dental hygienists experienced musculoskeletal symptoms. Improvements of working environments in dental clinics, reasonable number of patients for operation, methods for reducing physical burden, correct working positions and procedures are needed to prevent musculoskeletal disease development in dental hygienists.
