Analysis and prevention of ergonomic risk factors among dental students

The professional work usually carried out by the dental surgeons results in developing ergonomic risk factors such as forward bends and rotated positions of the body while handling variety of tools. The successful application of ergonomics assures high productivity, avoidance of illnesses and injuries and increased satisfaction among dental surgeons. The study was carried out to find the effectiveness of ergonomics awareness training programme in minimizing the ergonomic risk factors in dental surgeons. For this purpose, one hundred and thirty dental surgeons among post graduate dental students, faculty members and private practitioners from in and around Mangalore city, Southern Karnataka District, India, with more than one year of experience were selected by using non-probability convenience sampling method. A six week of ergonomics awareness training programme for selected dental surgeons was developed and imparted during the training. In order to determine the effectiveness of ergonomics awareness training programme, a pre-tested structured dental work station observation check list was used. The result indicates that, mean post-test scores of manual material handling (0.23), physical energy demands (0.18), instruments (0.00), environment (0.00) and other musculoskeletal demands (1.35) were lower than the mean pre-test scores i.e., 1.98, 1.95, 0.14, 0.01 and 7.53 respectively. Based on the results of the study we conclude that, ergonomics awareness training programme will be effective in minimizing the ergonomic risk factors in dental surgeons.

Ergonomic Risk

Prevention of health disorders and sexual development of society is a priority area of hygiene and preventive medicine. The introduction of information and communication technologies into the educational process is a new risk factor for the development of disorders of the musculoskeletal system in adolescents. Purpose of the study: assessment of ergonomic risk factors for the development of disorders of the musculoskeletal system in adolescents using personal electronic computers as teaching aids. Objects of research: sanitary-hygienic and ergonomic factors of learning conditions with the use of personal computers and the state of the musculoskeletal system of college students. Research in accordance with the requirements of bioethics, after signing the informed consent and their parents. The hygienic factors of the learning environment and the ergonomic characteristics of furniture (tables, work chairs) in computer science classes of the Saratov college were studied. Their assessment is given for compliance with sanitary and epidemiological requirements and anthropometric indicators of students. A questionnaire survey and physical examination of 308 adolescents were carried out to identify complaints and assess the condition of the musculoskeletal system. It has been established that the organization and ergonomic characteristics of workplaces equipped with electronic computers fully comply with hygienic and ergonomic requirements. This is the cause of postural disorders and the development of disorders of the condition of the musculoskeletal system of students. A high prevalence of clinical signs of disorders of the musculoskeletal system among adolescents was revealed. It has been established that compliance with ergonomic requirements in the organization of workplaces when using personal electronic computers is a prerequisite for the primary prevention of disorders of the musculoskeletal system in adolescents. To solve this problem, first of all, it is necessary to provide educational institutions with modern furniture that meets ergonomic requirements.
