FOREWORD
The
Dentsply”
Cavitrom
2001”
Ultrasonic
Dental
Unitis
precision
engineered
and
manufactured.
Designed
for
use
in
prophylaxis
treatment,
periodontia
and
other
ares
of
operative
dentistry,
the
Unit
is
manufactured
by
the
Cavitron
Division
of
Cooper
Medical Devices
Corporation,
New
York,
NY
and
distributed
by
Dentsply
International
Inc.
Essentially,
the
Unit
operates
by
converting
ordinary
AC
house
current
into
25,000
Hz
current.
This
in
turn
is
converted
by
means
of
the
handpiece
and
insert
into
25,000
microscopically
small
mechanical
strokes
per
second.
These
rapid,
microscopic
strokes
are
then
transmitted
to
the
insert
tip.
Applied
with
a
water
spray
and
a
light
guiding
touch,
the
activiated
tip,
in
conjunction
with
the
bubbling
action
of
the
water,
rapidly
and
gently
dislodges
calculus
and
stain.
CAUTION
The Dentsply-Cavitron Unit should not be used for restorative dental
procedures involving the condensation of Amalgam.
PRECAUTIONS: No special maintenance is required for the Dentsply-Cavitron Ultrasonic Dental
Unit, but the following precautionary measures should be exercised:
a. Do not place the Unit on or next to a radiator or other heat source as this may damage the
electronic components.
b. Do not keep the Unit in a tightly confined space or corner. Keep it where a normal amount of
air will freely circulate on all sides of the cabinet.
c. The Unit is portable, but when carrying it from one place to another, handle it with care.
d. THE IMPORTANCE OF THE FOLLOWING INSTRUCTIONS OUTLINED IN THE DENTIST'S
INSTRUCTION MANUAL CANNOT BE OVEREMPHASIZED. IMPROPER ANGULATION OF THE
INSERT TIP TO THE TOOTH WILL DEFINITELY RESULT IN SUB-STANDARD PERFORMANCE OF
THIS PRECISION EQUIPMENT.
; WARNING
WE RECOMMEND THAT THE ULTRASONIC UNIT NOT BE USED IN CASES WHERE A PATIENT OR AN
OPERATOR OF THE UNIT HAS BEEN FITTED WITH A CARDIAC PACEMAKER.
For further information on this subject, we suggest you refer inquiries to Annals of the New York
Academy of Sciences, Vol. 167, Article 2, pages 515-1075, “Advances in Cardiac Pacemakers”,
U.S. Department of Health, Education and Welfare, “Electromagnetic Radiation Interference with
Cardiac Pacemakers”, and the Journal of the American Dental Association, Vol. 91, No. 6, Pages
1224-1229, “The Individual with a Pacemaker in the Dental Environment.”

DESCRIPTION
COMPONENTS
The Unit has four major components: an electronic generator, a handpiece assembly
(retraction reel optional), a set of interchangeable inserts, and a foot (fingertip control
optional) control.
GENERATOR AND WATER SYSTEM
The electronic generator enclosed in the cabinet produces the power required for activating
the handpiece. The following controls are found on its control panel (Figure 1):
a.
Power Adjustment Dial (1) to switch the Unit on and off and to select the 1, 2, or 3 power
levels of operation.
Water Flow Adjustment Knob (2) for adjusting the volume of water permitted to flow from
the handpiece. The greater the water flow, the lower the water temperature; the lesser the
water flow, the higher the water temperature.
On-Off Pushbutton turns the Unit on.
On-Indicator Light (4) illuminates when the Unit is on.
Handpiece (5).

2. HANDPIECE AND CABLE ASSEMBLY
The Handpiece and Cable Assembly (Figure 2) consists of a handpiece which is the housing for
the interchangeable inserts, and a cable which can be optionally attached to a retraction reel.
a. The open end of the handpiece is designed to accept inserts of various tips (see Figure 3). To
change inserts, simply pull out one and place in another, making certain that it is fully
seated. WITH INSERT IN PLACE, HOLD HANDPIECE IN AN UPRIGHT POSITION. ACTIVATE
THE INSERT TO BLEED ANY AIR BUBBLES THAT MIGHT BE TRAPPED WITH THE HANDPIECE.
(With the finger switch handpiece, hold the switch “ON” until the water flows without
spurting.)

FIGURE 3. PLACING INSERT INTO HANDPIECE
CAUTION
If the insert does not readily snap into the handpiece moisten the “O" ring,
located immediately below the collar. (See Figure 4.) DO NOT FORCE into
place. On handpiece with the finger switch, twist the insert clockwise as it is
pushed into the handpiece.
을 b. The handpiece, with the insert in place, converts electrical power, supplied by the
generator, into microscopically small strokes which activate the insert tip. A continuous
flow of water is required to keep the handpiece cool. This same water, warmed within the
handpiece, is then delivered through the water outlet and sprayed by the activated tip.
C. The optional finger switch is located at the forward end of the handpiece and controls the
ON-OFF function of the handpiece. Flick the finger switch once and the handpiece instantly
delivers the selected power and water flow. Flick the finger switch again and the handpiece
is OFF.
Units with the finger switch will automatically shut OFF if the finger switch is actuated
with no insert in the handpiece. |
