The present study investigates dental work in terms of time distribution and mechanical exposure in value-added and non-value-added tasks. Further rationalization of dental work would typically involve an increase in the proportion of value-added tasks. Information on mechanical exposure within classes of value-added and non-value-added tasks can be used to predict possible implications of rationalization.
Twenty-four dentists were investigated. Using a data logger, postures and movements were continuously recorded for each subject during four hours of work, which included 45 minutes of video recording. Time distribution and mechanical exposure for each work activity were calculated from the video recordings, using a loss analysis technique. Value-added tasks, which comprised 57% of the total working time, generally implied significantly more constrained mechanical exposures as compared with non-value-added tasks.
The results indicate that future rationalization of dental work, involving a reduction of nonvalue-added tasks, may increase the risk of developing musculoskeletal disorders.
