Study: Aspiration tips under the ergonomic comparison at the work of dental hygienist.

The study aimed to determine if the use of the ErgoFinger® HVE is more ergonomic than using a standard HVE. The study was made by Kati Saarinen and Kirsi Taalikka. The comparison between the two HVE's was made with qualitative study methods at the Oral Hygiene Teaching Clinic of Metropolia University of Applied Sciences, Helsinki, Finland.


The work of a dental hygienist is physically stressful. Work simultaneously requires static strength, fine motor skills and, precision. Musculoskeletal disorders are prevalent in dental hygienists. They most commonly occur in neck and shoulder pain as well as back symptoms. In the work of a dental hygienist, musculoskeletal disorders are caused by awkward working positions and static work. These lead to muscle tension, which in turn causes pain in the neck, shoulder area, and lower back.


The ergonomic working position and the choice of the right tools affect the well-being at work. The dental hygienist's working day consists mainly of periodontal disease treatment and tasks related to preventing periodontal disease. The measures include removing dental calculus by ultrasonic machine and air polishing. With these devices, the spray and splatter are removed by suction during the procedure. Standard HVE has adverse properties which challenge the dental professional, especially when working alone. Tasks related to debris or liquid removal dictate that the dental professional work in uncomfortable and static working postures.


The study proved that working with the ErgoFinger® is more ergonomic than working with the standard HVE. Positioned on the finger, the ErgoFinger® ergonomically reduces strain and allows for a comfortable and correct posture for the wrist, fingers, arms, and shoulder area. Using the ErgoFinger® reduces static neck flexion and shoulder abduction. ErgoFinger® also reduces the need to hold the wrist in a non-neutral position. There is no need to keep the fingers in a tight pinch grip; thus, musculoskeletal disorders can be reduced. In conclusion, the use of the ErgoFinger® improves working ergonomics and impacts well-being at work.
