Ergonomics in dentistry

MOST DENTISTS SUFFER FROM OCCUPATIONAL STRAIN

According to the “European Society of Dental Ergonomics”, about 65 % of all dentists have musculoskeletal complaints varying in severity but involving one or more of the following: discomfort, pain, limitation of functioning and loss of working time. The risk of disability is considerable.

The reason is that dental practitioners often work in static unhealthy postures – and in some cases even with the units out of sight and reach.

Traditionally the unit instruments have been placed “to the left” of the chair:

  • To reach a unit instrument the practitioner must look away from the area of treatment and turn the body
  • In doing so, the practitioner needs to move the hands from the primary area of work
  • As a result, the focus on the treatment is repeatedly disrupted
  • The eyes become tired from constant adaptation and accommodation (adjustment of the eyes to differences in light and changes in distance of objects)
  • The practitioner must carry the full weight of instrument and hose
  • The chairside assistant cannot help the dentist change contra-angles and burs and cannot transfer unit instruments to the dentist
  • The instrument holders are closed and difficult to clean and disinfect

Solo work

When working solo, it is particularly important that all instruments are located within a short reaching distance.

During endodontic treatment, it is useful to position a tray under the instrument bridge so that the endo files are within easy reach of the right hand.
