Knowledge, prevalence, and risk factor for lower back pain among dentists in Kollam District, Kerala: A questionnaire survey

Context: Musculoskeletal disorders (MSDs) are one of the common occupational hazards among health-care workers. The common cause includes work-related factors such as awkward postures and repetitive motions affecting the back, neck, shoulders, elbows, hands, and wrist, thereby increasing dentist's exposure to MSDs. By following proper postural ergonomics, these could be avoided. Aims: The aim of the study was to evaluate the knowledge, prevalence, and risk factors for lower back pain among dentists in Kollam district, Kerala. Settings and Design: A cross-sectional study was conducted among clinical dentists working in Kollam for the past 15 years. Subjects and Methods: A structured questionnaire in English comprising 25 questions evaluating the prevalence and awareness of ergonomic postures and methods to reduce it was used. Statistical Analysis Used: Data were entered into Microsoft Excel and analyzed using the SPSS for Windows version 17.0. P < 0.05 was considered statistically significant. Results: A total of 77 clinical dentists practicing in Kollam received and responded to the survey and results showed that cause for lower back pain as due to improper chair height (50.6%), frequently change posture between procedures (75.0%), and back pain due to lifting pediatric patients from chair (23.1%). Only 72% of those who did minor stretching exercises, 88% of those who rested their back while working, and 64% of those who stopped working when pain arises did not show pain due to practice. Conclusions: Performing proper postural ergonomics on daily practice, taking microbreaks and resting the back while working can prevent MSDs.
