Abstract : Dentistry is a physically demanding profession in nature that necessitates static work in incorrect postures for prolonged time. Tight workspace, restricted space for movement in dental clinics and limited visual access to the oral cavity lead to adoption of incorrect postures, which will lead to work-related musculoskeletal disorders on the long term. Ergonomics is an approach that allows dentists to work safely by designing tools, equipment and work stations in a way that provides maximum efficiency and minimal injuries at the same time. Education on ergonomic and providing appropriate work environments may be effective in reducing work-related musculoskeletal disorders among dentists. 141 dental interns (42 males and 99 females), with age range 22-25 years, were included in this study. The participants’ knowledge, attitude and practice of ergonomic principles were evaluated at baseline and after education sessions on ergonomics using a self-structured questionnaire. The participants were randomly assigned to two groups, where one group received an informative lecture on ergonomics in Dentistry followed by clinical demonstration on correct ergonomic posture. The other group received the same lecture followed by a computer-aided session on ergonomic postures using previously prepared videos. There was a statistically significant difference (p<0.001) regarding each of knowledge, attitude and practice scores measured at different intervals, with scores measured at baseline being significantly lower than scores measured after education on ergonomics in both groups. Both educative methods were shown to be effective in the promotion of knowledge, attitude and practice among participants.
