3.1 Precautions for All Systems
Ultrasonics
• 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 Water
Supply under Section 9: System Care.
• Close the coolant water shut-off valve to the System every
night before leaving the office. The use of an in-line water
filter is recommended.
2.1 Contraindications
• Ultrasonic Systems should not be used for restorative
dental procedures involving the condensation of
amalgam.
• For best performance, use only ultrasonic inserts
manufactured by Dentsply
®
Preventive Care.
• Use only Cavitron
®
Prophy-Jet
®
Cleaning Powder.
1.1 Ultrasonic procedures
• All general supra and subgingival scaling applications.
• Periodontal debridement for all types of periodontal
diseases.
• For patients with a history of sensitivity to ultrasonics.
• Endodontic procedures.
2.2 Warnings
• Persons fitted with cardiac pacemakers have been
cautioned that some types of electronic equipment might
interfere with the operation of a pacemaker. Although no
instance of pacemaker interference has ever been reported
to DENTSPLY
®
, we recommend that the handpiece and
cables be kept at least 6 to 9 inches (15 to 23 cm) away
from any pacemaker and pacemaker leads during use.
• Do not direct the air polishing stream at soft tissue or
into the sulcus. Tissue emphysema has been reportedly
caused when the air/water/powder stream was directed
at the soft tissues or into the sulcus.
Air Polishing
• 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 cleaning powder and clogging the lines at the
air polishing tip.
• Cavitron
®
Prophy-Jet
®
Cleaning Powder is a water-soluble
sodium bicarbonate powder specially formulated for use in
1.2 Air polishing procedures:
• Removal of a variety of extrinsic stains, e.g., tobacco,
coffee & tea, chlorhexidine.
• Prophylaxis of orthodontic patients.
• Preparing tooth surfaces prior to bonding and sealant
procedures.
3.2 Precautions for Ultrasonic Prophylaxis
Procedures
• Like a toothbrush, ultrasonic inserts “wear out” 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 2 mm of
wear to maintain optimal efficiency and avoid breakage.
• If excessive wear is noted, or the insert has been bent,
reshaped or otherwise damaged, discard the insert
immediately.
• 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
mouth.
Cavitron
®
Air Polishing Systems. Do not attempt to use
any other cleaning materials in the air polishing powder
reservoir.
• Empty the air polishing powder reservoir at the end of
the day to prevent “caking” of the powder and clogging
the lines and air polishing tip.
