Correlation of Biomechanical Exposure with Cumulative Trauma Disorders of Upper Extremity in Dental Surgeons

Aims and Objectives: The aim of this study was to determine the occupational musculo-skeletal problems in dentists and to investigate the related risk factors. Biomechanical risk exposures measures are available as is various activity limitations. Activity limitation is specific for various cumulative trauma syndromes found in dental occupation. Hence, this study aims at correlating these two parameters. Study population involves private and institutionalized dentists. So study aims to do a comparison in between the groups also. Materials and Methods: 250 dentists working in Navi Mumbai and Mumbai were included in the study. Their mean ages were 30.15 ΁ 5.70 years. The musculo-skeletal system problems, activity, limitations, pain levels, working posture are some of the factors investigated. Results: The biomechanical exposure analyzed (rapid upper limb assessment, occupational repetitive action) showed strong association with various cumulative trauma disorders assessed by (neck disability index, disabilities of arm, shoulder, hand, and carpal tunnel syndrome questionnaire). Conclusion: Musculo-skeletal problems existed due to the occupational working conditions and these problems caused activity limitation with varying degrees. Occupational risk factors in dentists make dentists conscious about this issue and also preventive rehabilitation programs have to be planned.
