Prevalence of musculoskeletal disorders among orthodontists in Alberta

Ergonomic problems have been noted among the hazards in the dental workplace. Many surveys have suggested that dental professionals may suffer from musculoskeletal disorders (MSDs) of the low back and neck as well as other MSDs. This survey aimed to look deeper into MSDs among orthodontists and provide a starting point to direct ergonomic intervention. The standardized Nordic questionnaire was mailed out to all registered orthodontists in Alberta, Canada. There was a 52.4% response rate from a sample of 61. Seventy-two percent of the respondents were male and 28% were female. The results showed low back trouble to be the most prevalent MSD (59%), followed by neck (56%), and shoulder trouble (47%). There was no significant differences in MSD prevalence between gender (p > 0.4), and no correlations existed between age, years of work, and number of hours of practice per week (p > 0.3). These results were consistent with other studies surveyed on dental professionals for the number and type of MSDs present. Further attention should be directed towards risk factors and ergonomic intervention.
