Clinical Findings Related to Musculoskeletal Disorders (MSDs) in a Group of Orthodontists

Abstract

Aim: Orthodontists may be exposed to a variety of occupational hazards and may be affected by conditions such as musculoskeletal disorders (MSDs). Prevention strategies are required to identify risk factors at different levels. Through an objective clinical evaluation, this study aimed to identify the factors related to the presence of MSDs in a group of orthodontists from Medellín (Colombia). Methods: A cross-sectional study was conducted. A clinical evaluation, focusing on the occupational aspects related to orthodontics, was carried out by an occupational health physician, which was standardized for research purposes. Sociodemographic and clinical variables were collected. Descriptive and bivariate analyses were conducted on the prevalence of MSDs according to the study variables and Chi-square tests were carried out to observe statistically significant differences. Ethical approval was obtained. Results: The prevalence of MSDs was 58.7% (95%CI 44.3- 71.7). The frequency of upper body MSDs was 45.7% (women: 51.4%), and in the Spine area was 23.9% (men: 45.5%). The prevalence of MSDs was higher in men those people ≤ 44 years, single/separate, from middle socioeconomic status, and with other medical previous conditions. Labor conditions were related to the presence of MSDs. The agreed percentage for self-perceived symptoms of MSDs and those found for clinical evaluation was for upper body MSDs and clinical Spine area MSDs considering positive cases was 50% and 29.2% respectively. Conclusions: The orthodontists participating in the study manifested various MSDs and other pathologies related to their professional practice. Sociodemographic and clinical factors were related to the presence of MSDs. Epidemiological surveillance systems in occupational health and strategies in health and safety at work are requested.
