Abstract :

Working in a dental laboratory poses some risks pertaining to musculoskeletal system due to prolonged involvement in production process of dental and orthodontic technologies. Apparently, there are some reports about the factors cause the risks experienced by dental technicians. Therefore, this research aims to study the correlation of personal and work related factors to subjective musculoskeletal disorders (MSDs) among a number of dental technicians working at the ABADI Dental Laboratory.       This research applied descriptive observation using cross sectional approaches. As the sampling of the research population, a total of 11 dental technicians in the laboratory was selected as the respondents. To be specific, this research measures the variables including individual factors (age, sex, smoking habit, body size, and waist circumference), job factors (awkward posture, repetitive motion, vibration, rest break, workstations), and subjective complaints related to the musculoskeletal system. Later, the variables were analyzed by using coefficient contingency (C) in order to test the strength of relationships among the variables.       Conclusively, the findings of this research showed that there were four significant degrees of correlation among the variables. The high correlation lied between the sitting height of the female respondents and the risks of MSDs. The medium correlation occured between the risks and the female respondents’ body size, which includes the measurements of sitting elbow height, sitting knee height, as well as the length of upper legs and lower legs. The correlations between MSDs and sex differences, smoking habit, the male respondents’ length of upper legs and lower legs were considered low. Then, the very low correlations were found between MSDs and age as well as MSDs, sitting height of the male and waist circumference  respondents.       From the findings, it is recommended for the ABADI Dental Laboratory to give a ten-minute break every hour or a 15-minute break in every two-hour working for stretching and providing chairs with height adjustment features and footrests.
