Abstract

Background: Musculoskeletal disorders are common problems among dentists. These conditions may lead to inappropriate postures and impairment in physical and psychological function. On the other hand, poor postures and inappropriate ergonomic may result in a wide variety of musculoskeletal disorders. Objectives: The aim of this study was to investigate the prevalence of common postural disorders of the spine and shoulder girdle among the dentists and possible correlations between demographic, anthropometric and occupational characteristics with these abnormal postures. Patients and Methods: In a cross-sectional study, 96 dental staff including academic staff, residents and senior students of Tehran University of Medical Sciences was enrolled. Data were collected using a questionnaire and posture assessment tools such as plumb-line, checkerboard and flexible ruler. Data analysis was done with SPSS version 17. Results: The prevalence of the forward head posture (FHP), rounded shoulder posture (RSP), scoliosis and hyperlordosis were reported in 85.5%, 68.8%, 18.8% and 17.3% of the participants, respectively. A significant correlation was found between gender and FHP (P = 0.04) and also scoliosis (P = 0.009). On the other hand, a significant correlation was seen between weight and hyperlordosis (P = 0.007). Conclusions: Our study revealed a high prevalence of postural disorders especially FHP, RSP and scoliosis among Iranian dental staff. The female dentists were less susceptible to FHP and scoliosis. © 2016, Sports Medicine Research Center.
