Per FCC Part 15.21, changes or modifications not
expressly approved by the party responsible for
compliance could void the user's authority to operate
this equipment.
SECTION 4: Precautions

4.1 System Precautions

Do not place the system on or next to a radiator or
other heat source. Excessive heat may damage the
system's electronics. Place the system where air is free
to circulate on all sides and beneath it.
The system is portable, but must be handled with care
when moving.
Equipment flushing and dental water supply system
maintenance are strongly recommended. See Section
9: System Care.
Close manual shut-off valve on the dental office water
supply every night before leaving the office.
The use of an in-line water filter is recommended.
Never operate system without fluid flowing through
The use of an air dryer on the compressor line supplying
the System will prevent condensation from forming in
the air line which in turn may cause "caking" of the air
polishing powder and clogging of the lines and air
polishing nozzle.
Prophy Powders are specially formulated for
use in Cavitron
Air Polishing Systems. Do not use any
other materials in the air polishing powder reservoir.
Empty the air polishing powder bowl at the end of the
day to prevent "caking" of the powder and clogging of
the lines and air polishing nozzle.
Never operate the air polishing mode without fluid
flowing through the handpiece.

4.2 Procedural Precautions


The Cavitron JET Plus unit works with Cavitron inserts as
a system, and was designed and tested to deliver
maximum performance for all currently available
Cavitron and Cavitron Bellissima™ brand ultrasonic
inserts. Companies that manufacture, repair or modify
inserts carry the sole responsibility for proving the
efficacy and performance of their products when used
as a part of this system. Users are cautioned to
understand the operating limits of their insert before
using in a clinical setting.
Like bristles of a toothbrush, ultrasonic inserts "wear"
with use. Inserts with just 2 mm of wear lose about 50%
of their scaling efficiency. In general it is recommended
that ultrasonic inserts be discarded and replaced after
one year of use to maintain optimal efficiency and
avoid breakage. A DENTSPLY Professional Insert
Efficiency Indicator is enclosed for your use.
If excessive wear is noted, or the insert has been
bent, reshaped or otherwise damaged, discard the insert
Ultrasonic insert tips that have been bent, damaged, or
reshaped are susceptible to in-use breakage and should
be discarded and replaced immediately.
Retract the lips, cheeks and tongue to prevent contact
with the insert tip whenever it is placed in the patient's

Air Polishing

Patients who have severe respiratory illness should
consult their physician before undergoing air polishing
prophylaxis procedures.
Patients wearing contact lenses should remove them
prior to air polishing treatment.
Avoid use on cementum or dentin.
Direct contact of prophy powder with surfaces and
marginal areas of dental restorations should be avoided.
Set the air polishing powder flow control to the maximum
(H) position only when it is necessary to remove
particularly difficult stains. Return the powder flow
control to the medium position upon the completion of
the procedure.
JET Air Polishing Insert nozzles that have been bent,
damaged or re-shaped, are susceptible to in-use
breakage and should be discarded and replaced
Check o-ring and threads on powder bowl cap to
ensure a tight seal. If o-ring or threads are worn,
replace immediately.
Residual prophy powder in threads can result in
excessive wear and disengagement of the cap during
unit operation. Be sure to clean threads regularly as per
Section 9 System Care.
