Prevalence and Risk Factor associated with Musculoskeletal Pain among Students of MGM Dental College: A Cross- Sectional Survey

Abstract

Background: The aim of this study was to determine the prevalence and associated risk factors for development of musculoskeletal pain among the dental students of 3rd, 4th year and interns, at MGM Dental College, Navi Mumbai. Materials and methods: A valid and reliable close ended questionnaire was administered to 230 students of 3rd year, 4th year and interns who met the inclusion criteria. A response rate of 77% was achieved. The variables included in the questionnaire were (1) presence of pain, (2) awareness regarding correct posture, (3) areas of the body affected by pain, (4) clinical setting, (5) practices to reduce pain. Statistical analysis was applied using Chi-square test. Results: In this study, we found a total of 81% prevalence of musculoskeletal pain among the dental students. Eighty-one percent were unaware of the correct posture for dental clinical procedures. Statistical significance was observed between different clinical activities and musculoskeletal pain when Chi-square test was applied. Maximum pain was observed in the hand (92%) followed by wrist (85%) and lower back (72%). Sixty-three percent of the students having pain performed cervical flexions and torsions to improve vision of the oral cavity. Seventy-five percent of the students reported that they were uncomfortable with their current working stool. Five percent of the participants performed exercises after clinical practice of which none reported musculoskeletal pain. Conclusion: Dental students are prone to development of musculoskeletal pain due to lack of awareness regarding correct posture, prolonged static postures, inadequate operating stools and lack of exercises.
