Instrumental overview
The FDA considers a hand scaler or
curette a Class I medical device. A Class I
medical device as defined by the FDA:
"An instrument ... which is: intended for
use in the diagnosis of disease or other
conditions, or in the cure, mitigation,
treatment, or prevention of disease, in man
or other animals, or intended to affect the
structure or any function of the body of
man or other animals, and which does
not achieve its primary intended purposes
through chemical action within or on the
body of man or other animals and which
is not dependent upon being metabolized
for the achievement of any of its primary
intended purposes." 1
Hand scaling instruments enter the
body's tissues, altering them for better
(with calculus removal) or worse (with
tissue trauma). If an incorrect edge or an
incorrectly sharpened blade is activated, it's
likely that burnished calculus will remain
embedded in the root surface.
Recent observations during dental
perioscopy detected ulcerated tissue and
calculus deposits adjacent to one another.
The inflammation was more severe when
both calculus and biofilm were present than
areas of biofilm alone.2 This reinforces the
value of hand scaling with a quality working
edge as an essential component of root
debridement.
In addition to the clinical benefits of a
precise edge during calculus removal, there
are ergonomic benefits for the practitioner.
A lighter grasp and less pressure are needed
when there is a sharp "bite" from the instrument. Lighter scaling strokes enable the
practitioner to maintain proper positioning
during treatment which help lessen fatigue
in the hand, shoulder and neck.
Treatment is more efficient when it
requires fewer strokes for complete calculus
removal. Patient comfort also increases
when there is lighter pressure and decreased
working time.
Fine points and
sharpening stones
The purpose of sharpening an instrument
is to restore its sharpness while preserving
the original integrity, contour and angle
of the instrument. There are a number of
