Ergonomics for the Dental Hygienist

1.    Avoid bent hand/wrist positions. Try to work around the clock to reach both sides of the mouth versus staying on one side.  Have patient move their head instead of you trying to bend your body/hands to reach a particular area.

2.    Use gloves that do not resist the natural movements of the hands.  Gloves that are specifically designed for right and left is better than ambidextrous gloves.

3.    Use ultrasonic scaling devices whenever possible-especially for heavy calculus deposits.

4.    Use sharp instruments.  This will reduce operator fatigue by decreasing the number of strokes needed.  Grasp can also be more relaxed.

5.    Use hollow instruments with knurled handles (waffle-iron is the best).  Larger diameter handles are better. They should be balanced so the working ends are centered on a line running through the long axis of the handle.

6.    Use chairs that allow easier access to the patient.  You should be able to sit close to the patient's head or straddle the headrest when sitting behind the patient.  Chairs should be easily adjustable in height and the back supported.

7.    Make sure all mechanical equipment is in good working order and regularly lubricated.

8.    Place "table" of instruments and devices in easy reach position.  When picking up things like the polisher or water, make sure you can pick it up with a neutral wrist position.  Do not turn hand palm up (supinate) excessively so that when you bring the instrument/tool toward the patient to perform the task you will have it in the right position.  It is better to pick up the tool with palm down and then reposition it before using it on the patient.   Make sure all tubes and wires that are attached are free from resistance.  Putting these up overhead would be ideal.

9.    Provide a manageable workload. It is recommended that hygienists have no more than 10 patients per day if working just two days, 9 patients per day if working 3 days and 8 patients per day if working 4 days.  If working 4 days per week, try to schedule no more than 2 days in a row.  Spread out heavy calculus patients as much as possible so they are not back to back.  One hour per patient is considered a reasonable work pace.

 Take advantage of rest breaks whenever possible.
