Incorporating a variety of instruments into
your armamentarium provides benefits for
patient care, as well as body mechanics.

Many clinicians are unaware that new and
innovative instruments are introduced every
year by many different instrument companies.
If you are still using the same instruments that you started
with during dental hygiene school, consider expanding your
horizons with some new and, in many instances, improved
hand instruments. Like the rest of the modern world, the
technology of instrument development changes rapidly. Metals
have been vastly improved, handles are much more
ergonomic than previous versions, and old standards have
been tapered, modified, or miniaturized. Following are some
innovations that you may want to consider adopting into
your own instrument armamentarium.

(left) and USC Barnhart 5/6 (right).
American Eagle Instruments offers the unique Scandette all
purpose double Gracey curet made with the gold-colored
XP™ Technology metal that never needs sharpening (Figure 1,
page 46). This innovative modification of the Gracey design
has very sharp blades that are beveled in two directions. One
bevel on each blade is honed like a Gracey 13/14 for distal surfaces
and the other bevel on the same blade is angled like a
Gracey 11/12 or 15/16 for mesial surfaces. The paired offset
bevels on these curets make them truly universal. The new
Scandettes can be obtained with standard or mini blades and
are designed for fine scaling and root planing with light pressure
after you have removed any heavy calculus with larger
ultrasonic inserts/tips or larger hand instruments.
G. Hartzell & Son just introduced a more rigid, heavier
version of the Columbia 4R/4L universal curet, called the
Columbia 4R/4L H, which is ideal for heavy calculus
patients with looser tissue (Figure 2, page 46). If you like
the Columbia 4R/4L but wish it was more substantial in the
shank to better remove tenacious or burnished calculus on
the distals of molars, the Hartzell Columbia 4R/4L H may
be a wise addition to your armamentarium.
Hu-Friedy Mfg Co Ltd recently released the USC Barnhart 1/2
and USC Barnhart 5/6 universal curets (Figure 3). Introduced in
2011, the USC Barnhart curets are named for the University of
Southern California (USC) because they were developed in close
collaboration with the USC dental hygiene faculty. The USC Barnhart
1/2 curet is designed with a thin, sharp cutting edge that will
slip easily under tight tissue and access all areas of the mouth. It is
ideal for patients with light calculus but is also strong enough for
use on teeth with moderate calculus. The
USC Barnhart 5/6 is similar to a Columbia
13/14 universal curet, but the blade is
longer and more substantial in order to
be more effective on the proximal surfaces
of the molars.

Paradise Dental Technologies (PDT) has
introduced the R144 Queen of Hearts™
periodontal curet, which features longer
cutting edges and a close-faced blade for
fine finishing with minimal tissue distension
(Figure 4). This curet is designed to improve access to root concavities,
deep pockets, and
furcations, with better adaptation.
In March, American Eagle
Instruments Inc released the BlackJack Universal Sickle Scaler,
designed for anterior and posterior adaptation (Figure 5). Featuring
a contra angle and thin blade, the BlackJack is also made with XP
Technology, to ensure the blade maintains its shape over the life of
G. Hartzell & Son makes the 204SD posterior sickle scaler, a
modification of the traditional 204S posterior sickle (Figure 6). This
sickle scaler is strong and sharp and adapts beautifully for subgingival
removal of moderate to heavy ledges of calculus. The Hartzell
204SD has a more open shank angulation than the 204S, which
allows it to adapt well to posterior proximal surfaces. It is designed
for scaling of residual interproximal calculus on both posterior and
The Nevi 3 and Nevi 4 sickle scalers
(Hu-Friedy Mfg Co Ltd) are new double-ended posterior sickles with curved,
thin, mirror image ends (Figure 7 and
Figure 8). Both are made with very
sharp, strong EverEdge metal that provides
the strength necessary for the
removal of moderate to heavy calculus
either before or after ultrasonic scaling.
The smaller bladed Nevi 3 is actually
patterned very closely after the Wyland
carver, a restorative instrument originally
designed for finishing of interproximal
amalgam margins. The Nevi 4
is a larger bladed, all purpose sickle
scaler with sharp, sturdy, and tapered
blades designed to remove moderate
to heavy calculus ledges. Although
both are classified as posterior sickles,
they are useful for adaptation on anterior
proximal surfaces as well.
PDT's Montana Jack® sickle scaler is a
popular instrument (Figure 9). Clinicians
remain impressed by the utility of this
instrument especially for use on children
and adult maintenance patients with
tight tissue or tight contacts. This allpurpose
sickle is thin enough for the
tightest anterior contacts and still strong
enough to remove moderate interproximal
ledges of calculus on posterior teeth.
A rigid version is also available.
American Eagle Instruments Inc has
created a new line of instruments
that will not damage or scratch titanium
implants (Figure 10). The line
is made out of medical grade titanium and features the lightweight
EagleLite handle to reduce hand fatigue.
Nordent Manufacturing Inc also makes instruments for use on
implants—the ImplaMate Titanium Implant Instruments (Figure 11).
Although there are six different design choices, the universal Barnhart
5/6 curet in this pure titanium set is the smallest and most versatile.
It is thin enough to insert easily under tight tissue and small enough
to adapt to the contours of most implant restorations.
The Wingrove™ Titanium Implant Instruments (PDT) were
designed by Susan Wingrove, RDH, an Iowa dental hygienist with
many years of periodontal practice experience (Figure 12). These
uniquely processed titanium instruments are made from USA medical
grade titanium so they will not scratch implants, and they also have
thin, durable blades that can be sharpened.
Premier Dental Products Co
has engineered a new instrument
that helps instruments maintain
their sharp, well-defined
edges (Figure 13). The technology
is designed to create
instruments that require less
pressure by the clinician to
reduce operator fatigue, while
achieving the same level of
biofilm removal. The proprietary technology
is the result of engineering and metallurgical
innovation and is available in all
Premier scalers and curets.
Dental instrument manufacturers continue to create new and improved instruments
to improve efficiency, efficacy,
and ease of use. It is our responsibility as
dental hygienists to make sure we are
using the most up-to-date instruments
to provide our patients with the best care
