Scalers are held in the modified pengrip (between the thumb, the index finger and the middle finger). Since instruments for scaling and rootplaning are used with a certain amount of pressure a correct grasp, proper point of support and stable but flexible finger rest are very important.
The scaler H6/H7 is used for the removal of calculus (and plaque) in the anterior and premolar regions.
Scalers are suitable for removal of calculus up to a pocket depth of 3 mm. In deeper pockets the chances that the sharp tip of the instrument can cause damage to the surrounding tissue is too great.
