In this study, the work of the dentist and the identification of musculoskeletal disorders have been characterized. The analysis and compatibility with literature on the identification of musculoskeletal disorders resulting from professional work of dentists have been presented. The authors assessed the occupational risks associated with static load on the position of the dentist by means of the OWAS method.

In the implementation of specialized services a large attention is paid to the flow of information between cells which determine the proper execution of the task. In engineering services related to dentistry there appears to be a significant discrepancy connected with knowledge awareness. The article presents three areas of knowledge (in the range and possession of the required knowledge) and information flow between the patient, dentist and dental technician. A technical solution to increase the possibilities of obtaining information at the design stage of the restoration has also been proposed, by introducing a system of material selection and engineering techniques in dentistry.

The article presents the results of surface topography measurements of the Nd‒Fe‒B type bonded magnetic material before and after the corrosion test in aggressive environments. The roughness of composite materials is closely related to the technological process. The increase in values of surface roughness parameters weakens the corrosion resistance by development of the actual surface and increases the contact surface with corrosive media. The results are a contribution to further work on the selection of appropriate technological parameters ‒ among others enlargement of the bio-polymer content which contributes to the homogenisation of powder composition and thus has a beneficial effect on the resistance of material to an aggressive environment in a long-term use.
