Journal Title: Eskişehir Osmangazi Üniversitesi Mühendislik ve Mimarlık Fakültesi Dergisi - Year 2018, Vol 26, Issue 2
Abstract
Dentistry profession involves in prolonged static muscle loads, highly repetitive and monotonous work, high force exertion or mechanical compression of tissues, and using vibrated tools. Therefore dentists are exposed to work-related musculoskeletal disorders (WRMSDs), which results in costly health problems and early retirements. This research aims to determine the risk factors of musculoskeletal discomforts among dentists, and to identify the impact of the dental tasks on the body regions during particular treatments. A questionnaire is created and fulfilled by 67 dentists from universities, hospitals, and dental offices. Electromyography studies were applied on six body regions of randomly selected three dentists during most common dental treatments. Discriminant Analysis was applied to determine whether a set of variables is effective in predicting category membership, and to identify statistically significant factor(s) which contribute(s) formation of the WRMSDs. ANOVA was utilized to analyze the results which were obtained from sEMG experiment and to determine the risk factors of work related musculoskeletal disorders. The most common position of the dentists while performing their profession was static and prolonged sitting / standing position. Musculoskeletal discomforts were experienced during the past 12 months in neck, hand / wrist, upper back, and shoulder regions; and during the past 7 days in elbows, feet, hip, and wrist / hand regions. There is no significant factor on dental filling therapy, tooth cleaning, fixed prosthodontics, and removable prosthodontics treatments. However, body region is the only significant factor on tooth extraction, endodontic and dental examination treatments.
