insert tip is placed in the patient’s mouth, the lips,
cheek and tongue should be retracted to prevent
accidental (prolonged) contact with the activated tip.
Turn Power Level Control to select ultrasonic power level
•
for operation. Clockwise increases system power.
Power level will increase throughout the full range of the
control. Hold the handpiece over a sink or drain. While
in Tap-On
TM
mode, simply tap the Tap-On
TM
Foot Pedal
to activate the system. (If Tap-On
TM
mode is turned off,
press and hold the Tap-On
TM
Foot Pedal down to activate
the system.) Check water spray to verify fluid is reaching
the working end of the insert tip. Adjust the water lavage
control until the water (lavage) flows with a rapid drip or
small spray.
Higher water flow settings provide cooler
irrigation.
It may be necessary to adjust lavage with the system in
•
“Boost” mode (Tap-On
TM
Foot Pedal fully depressed)
so adequate fluid will be available to cool tip to tooth
interface.
In general, it is suggested that a “feather-light-touch” be
•
used for ultrasonic scaling. The motion of the activated
tip and acoustic effects of the irrigating fluid, in most
cases, are adequate to remove even the most tenacious
calculus.
Periodically check the Cavitron Ultrasonic Insert for wear
•
with the Cavitron Insert Efficiency Indicator.
The use of a saliva ejector or High Volume Evacuator
•
(HVE) is recommended during all procedures.
Set the system’s Power Level Control to the lowest
•
efficient power setting for the application and the
selected insert.
Keep the foot pedal near your foot to make it convenient
•
to access.
9 6 Patient Comfort Considerations
Reasons for sensitivity
Incorrect tip placement. The point should never be
•
directed toward tooth root surfaces.
Not keeping tip in motion on tooth. Do not allow the
•
insert to remain in a static position on any one area of
the tooth. Change the insert’s path of motion.
Applying excessive pressure. Use a very light grasp
•
and pressure, with a soft tissue fulcrum whenever
possible, especially on exposed cementum.
If sensitivity persists, decrease power setting and/or
move from the sensitive tooth to another and then return.
9 7 Air Polishing Powder Bowl
Use only Cavitron
•
®
Prophy Powders in your Cavitron
®
JET
Plus Combination System. Any other substance or
additives may clog the system and will void the warranty.
For your convenience, the prophy powders are supplied
in bottles. Keep stored in a location that does not
exceed 95
o
F.
A special container is provided with your System for use
•
in emptying the powder bowl.
It is strongly recommended that the powder bowl be
•
emptied at the end of each day. This will reduce
moisture absorption and minimize clogging.
To fill, or refill, the powder bowl:
Turn the System OFF.
•
Unscrew the Powder Bowl Cap.
•
With the cap of the powder bottle closed, shake the
•
powder bottle vigorously to break up any lumps that may
have formed from settling. Carefully pour powder into
the bowl until the level reaches the top of the center
tube.
Using a soft dry cloth, remove powder adhering to the
•
cap and bowl threads. Secure the cap on the powder
bowl.
Turn the System ON.
•
NOTE: Use only Cavitron
®
Prophy Powders in the
system. Powder should be kept dry and stored
between 32
o
F/0
o
C and 95
o
F/ 35
o
C.
To adjust the flow of powder:
Adjust the powder flow rate by positioning the control
•
pointer on the cap at H (12 o’clock), M (9 o’clock) or L
(6 o’clock).
For heavy stain removal, set the control to H.
•
For light stain removal, set the control to L.
•
The control can be set at any position between H and L.
•
The view window at the center of the pointer lets you
•
observe the powder flow (small white circle of powder)
during operation. If no flow is seen, check for clogging
or add prophy powder.
9 8 Performing Air Polishing Procedures
Follow precautions listed in the General and Air Polishing
•
sections of 4.2 Procedural Precautions.
Place a 2 x 2 gauze on lip.
•
Select the proper amount of powder and water to create
•
the slurry needed using the Powder Flow Control on
the powder bowl cap and the Lavage Control on the
handpiece cable. Ensure that the system’s Power
Level Control is in the “Prophy Mode” range. Use more
powder for heavy stains and less powder for light stains.
With experience the Dental Healthcare Professional will
be able to determine the best flow rate settings for
optimum efficiency and patient comfort. Never operate
the system with powder only.
