Strains and Sprains in Dentistry

Dental clinicians are routinely exposed to various occupational hazards; chemical, biological and legal as well as ergonomic, which contribute to musculoskeletal disorders (MSD). The aim of the present study was to evaluate the prevalence of musculoskeletal disorders among dentists in South Kanara population and to determine the specialties associated with the highest risk of developing MSD. A total of 100 clinicians participated in the study which included a self assessed questionnaire to determine the site of pain and symptoms associated with it which was followed by the clinician assessed RULA questionnaire (Rapid Upper Limb Disorder Assessment) to determine the posture during their work, the risks associated and finally the need to improve the condition. According to the questionnaire survey, MSD’s were more prevalent among prosthodontists, endodontists, pedodontists & orthodontists compared to the other departments. According to RULA assessment endodontists and prosthodontists were at the maximum risk of developing MSD’s. Severe pain was due to high level of the RULA score; indicating that dentists with higher RULA scores needed to affirm to appropriate working postures. The study concluded that appropriate measures need to be taken into consideration to reduce the prevalence of musculoskeletal disorders to educate the dentists about the right ergonomic positions, awareness about work related risk factors and taking measures to lead a healthy life.
