Assessment of Knowledge about Ergonomics and Determining Musculoskeletal Disorders in Dentists: An Original Research

Abstract

Background: Musculoskeletal disorders (MSDs) are commonly occurring disorders nowadays. The present study was conducted with the aim of determining MSDs in dentists and to assess knowledge about ergonomics. Materials and Methods: This questionnaire study was conducted among 460 dental professionals of different age groups. Parameters such as posture of dentists, working alone or with an assistant, and number of breaks were recorded. Type of MSDs and the type and effectiveness were recorded. Results: BDS students were seventy, interns were 112, general dentists were 186, and specialists were 92. Year of practice was <5 years in 215, 5–10 years in 70, 10–20 years in 35, and >20 years in 140 students. Fourteen percent of students, 18% interns, 45% general practitioners, and 32% of specialists had a prevalence of MSD. Most common MSDs in students were upper back pain seen in 6%, in interns were upper back pain seen in 8%, in general practitioners were shoulder pain seen in 21%, and in specialists were hand/wrist pain seen in 10%. Forty-five percent of students, 67% interns, 72% general dentists, and 80% of specialists had idea about ergonomics. Seventy-four percent of students, 80% of interns, 83% of general dentists, and 87% of specialists think that ergonomics may improve performance. Sitting position was preferred seen in 53% of students, 58% of interns, 65% general dentists, and 60% of specialists. Forty-five percent of students, 47% of interns, 56% of general dentists, and 52% of specialists perform physical activity during work. The difference was found to be statistically significant (P < 0.05). Seventy-nine percent of students, 83% of interns, 86% of general dentists, and 88% of specialists show prolong sitting or standing. Conclusion: Authors found that all prefer to apply ergonomic in clinical practice. There is a lack of knowledge among BDS students and interns about ergonomics.
