The ergonomics is the fitting of technique and operation to the human being. Erconomics prima-ry task is to reduce work load and to keep people healthy and working. Dental hygienists work is physically very loading and these factors should be aware of the physical load so they can be prevented. Dental hygienists functional solutions of erconomics meaning is to reduce those things of they´s work. Purpose of this thesis is to reduce dental hygienists functional solutions of erconomics. The method of the acquisition of information of the functional thesis was a literature look. Re-search of this thesis was used international and finnish health databases. The material was sorted into four different sub-areas which where: working envinroment factors, working tools, working posture and work habits. The results focus on this thesis is physical erconomics. Physical erconomics of dental hygienist can be lightened according to the results with: finger support, loupes and with saddle chair. The results also told us how the instruments, noise, lightning and work pausing also affects ergo-nomics for dental hygienist. The results showed that the functional solutions mentioned above should be internalized in the dental hygienist training stage. The developing and maintaining of the ergonomics are the worker´s and the employer´s com-mon matter. If neccessary, should cooperate with occupational health care, in order to obtain physical stress risk factors mapped as early as possible. The finnish and international studies are needed in order to obtain a lighter physical ergonomics of the dental hygienist work.
