calculus relative to the gingival margin. The objective
of scaling is to remove calculus from the tooth surface.
This is easy to accomplish when the calculus is located
on the enamel of the tooth. Calculus attached to the
root surface, however, is embedded in the surface
irregularities and is much more difficult to remove.
The dentist or hygienist will smooth out the
irregularities and remove the calculus. As this is done,
some root structure is removed. This is referred to as
root planing. Several instruments have been designed
for scaling and root planing. They include sickles,
curettes, files, chisels, and hoes (illustrated in figure
6-6). We will discuss dental implant scaling
A sickle scaler (fig. 6-7) is primarily designed for
removal of supragingival calculus. Sickles with
straight shanks are designed to adapt to anterior teeth,
Jacquettes) adapt to posterior teeth and are illustrated
in figure 6-8. The basic characteristics of the sickle
scaler are they are triangular in shape, have two cutting
edges, and are pointed at the tip. The cutting edge is
