Introduction
The Cavitron Built-In Ultrasonic Scaler is equipped with a Sustained
Performance System™ (SPS), which offers a constant balance
between scaling efficiency and patient comfort by maintaining the
unit's power level when the insert tip encounters tenacious deposits
allowing the clinician to effectively scale even at a decreased/lower
power setting.
The System operates by converting an SELV source current into
high frequency current. The ultrasonic system consists of two
parts: an insert and the SPS electronic system. The SPS system
incorporates two closed loops. One loop provides automatic tuning
(operating frequency is adjusted to be at resonance for each insert).
The second loop automatically controls the tip stroke over different
working conditions. The DENTSPLY Cavitron Built-In scaler
produces 30,000 microscopically small strokes per second at the
insert’s working tip. This, combined with acoustic effects of the
coolant water, produces a synergistic action that literally “powers
away” the heaviest calculus deposits while providing improved
operator and patient comfort.

• It is the responsibility of the dental healthcare professional
to determine the appropriate uses of this product and to
understand:
• the health of each patient,
• the dental procedures being undertaken,
• applicable industry and governmental agency
recommendations for infection control in dental
healthcare settings,
• requirements and regulations for safe practice of
dentistry, and
• these Directions for Use in their entirety, including
Section 4 Precautions, Section 6 Infection Control, and
Section 10 System Care.
• This product is designed to assist in eliminating susceptibility
to retraction of oral fluids. To ensure adequate protection
from cross-contamination from other devices connected to the
dental unit, it is highly recommended that the dental unit be
installed with anti-retraction features. Additionally, the dental
unit, including the anti-retraction features, must be properly
maintained and periodically tested. For more information,
please contact your dental unit manufacturer.
• Where asepsis is required or deemed appropriate in the best
professional judgment of the dental healthcare professional, this
product should not be used, unless used in combination with a
Sterile Lavage Kit, (P/N 81340).
• During boil-water advisories, this product should not be
operated as an open water system (e.g. connected to a
public water system). Dental healthcare professionals should
discontinue use on patients and contact the local water authority
to determine when it is safe to continue use of this product.
When the advisory is cancelled, the local water authority should
provide guidance for flushing of waterlines. All incoming
waterlines from the public water system inside the dental office
(e.g., faucets, waterlines, and dental equipment) should be
flushed in accordance with manufacturer’s instructions for a
minimum of 5 minutes.
• Prior to beginning treatment, patients should rinse with a known
antimicrobial such as Chlorhexidine Gluconate 0.12%. Rinsing
with an antimicrobial reduces the chance of infection and
reduces the number of microorganisms released in the form of
aerosols during treatment.
• The use of high volume saliva evacuation (HVE) to reduce
the quantity of aerosols released during treatment is highly
recommended.
• Failure to follow recommendations for environmental operating
conditions, including input water temperature, could result in
injury to patients or users.
• Handle Cavitron insert with care. Improper handling of insert,
specifically the insert tip, may result in injury and/or cross
contamination.
• Failure to follow properly validated sterilization processes and
approved aseptic techniques for Cavitron inserts may result in
cross contamination.
• DO NOT mount the Cavitron built-in scaler outside of the
dental unit; doing so will void the warranty.

maintain optimal efficiency and avoid breakage. A DENTSPLY
Professional Insert Wear Indicator is enclosed for your use.
• If excessive wear is noted, or the insert has been bent, reshaped
or otherwise damaged, discard the insert immediately.
• Retract the lips, cheeks, and tongue to prevent contact with the
insert tip whenever it is placed in the patient’s mouth.
• Water should be used for all scaling procedures. Water flow is
adjustable from less than 10 to greater than 60 ml per minute.
• Only adjust the systems’s power adjustment knob with the
insert outside the patients mouth.
• As with all dental procedures, use universal precautions (i.e.,
wear face mask, eyewear, or face shield, gloves, and protective
gown).
Section 5: Adverse Reactions
None known.
Section 4: Precautions
• Equipment flushing and dental water supply system
maintenance are strongly recommended. See Section 10:
System Care.
• Verify handpiece fits properly in the dental delivery system
holder. If not properly seated, there is a potential for the
handpiece to slip out of the holder and be damaged or
contaminated. Contact a service technician for proper fit.
• 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 handpiece.
• Always ensure that the electrical connections on the handpiece
cable and the Steri-Mate Handpiece are clean and dry before
assembling them for use.
• Cavitron ultrasonic scaling units and Cavitron ultrasonic inserts
are designed and tested for safety and efficacy as a system.
Use of any other brand ultrasonic equipment with Cavitron
equipment has not been tested and may have a negative effect
on the safety and effectiveness of your Cavitron equipment and
their warranties. Please review the warranty statement enclosed
before use.
• Like bristles of a toothbrush, ultrasonic insert tips “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

Section 6: Infection Control
6.1 General Information
• For operator and patient safety, carefully practice the infection
control procedures detailed in the Infection Control Information
Booklet accompanying your System. Additional booklets can
be obtained by calling Customer Service at 1-800-989-8826,
Monday through Friday, 8 a.m. to 5 p.m. (Eastern Time).
For areas outside the U.S., contact your local DENTSPLY
Professional representative.
• As with high speed handpieces and other dental devices, the
combination of water and ultrasonic vibration from the Cavitron
Built-In Scaler will create aerosols. Following the procedural
guidelines in Section 9 of this manual can effectively control
and minimize aerosol dispersion.
6.2 Water Supply Recommendations
• It is highly recommended that all dental water supply systems
conform to applicable CDC (Centers for Disease Control and
Prevention) and ADA (American Dental Association) standards,
and that all recommendations be followed in terms of flushing,
and general infection control procedures (See Sections 7 and
10). Knowledge of and compliance with agency guidelines,
standards, and recommendations is the sole responsibility of the
dental healthcare professional.
• As medical devices, Cavitron products need to be installed
in accordance with local or national regulations, including
guidelines for water quality (e.g. drinking water). As an open
water system, such regulation may require your Cavitron
product to be connected to a centralized water control device
that prevents water contaminates from flowing back into the
water supply.
Section 7: Water Line Requirements
• Incoming water supply line pressure to the ultrasonic scaler
must be 25 psi (172 kPa) minimum to 60 psi (414 kPa)
maximum. If your dental water system's supply line pressure
is above 60 psi, install a water pressure regulator on the water
supply line to your ultrasonic scaler.
• Incoming water temperature to the Cavitron system should not
exceed 25°C (77°F). If needed device should be installed to
maintain a temperature within this specification, or a Cavitron
DualSelect Dispensing System attached to allow this system to
be operated as a closed water system.
• A manual shut-off valve on the dental water system supply line
should be used so that the water can be completely shut-off
when the office is unoccupied.
• A filter in the dental water system supply line is recommended
so that the particles in the water supply will be trapped before
reaching the ultrasonic scaler.
• After the above installations are complete on the dental water
supply system, the dental office water line should be thoroughly
flushed prior to connection to the ultrasonic system.
• After flushing system, verify there are no leaks.

The many styles of DENTSPLY Cavitron ultrasonic inserts are easily interchangeable for various procedures and applications.

ENGLISH • 10
Section 9: Techniques for Use
9.1 Patient Positioning
• The backrest of the chair should be adjusted for optimal access
to both the upper and lower arches. This assures patient comfort
and clinician visibility.
• Have the patient turn head to the right or left.
• Position chin up or down depending on the quadrant and surface
being treated.
• Evacuate irrigant using either a saliva ejector or HVE.
9.2 Performing Ultrasonic Scaling Procedures
• The edges of DENTSPLY Cavitron ultrasonic inserts are
intentionally rounded so there is little danger of tissue laceration
with proper ultrasonic scaling techniques. Whenever the insert is
placed in the mouth, lips, cheek, and tongue should be retracted
to prevent accidental prolonged contact with the activated tip.
• Always adjust the lavage so adequate fluid will be available to
cool tip and tooth surface.
• In general, use a “feather light touch” both supra- and
subgingivally. The motion of the activated tip and acoustic
effects of the irrigating fluid, in most cases, is adequate to
remove even the most tenacious calculus.
• Set the system power adjustment knob to the lowest power
setting for the application and the selected insert.
• Only adjust the system power adjustment knob with the insert
outside of the patient's mouth.
8.4 Foot Control Information & Operation
• The dental unit manufacturer provides the Foot Control.
Refer to their directions for use for operating characteristics.

cable connector.
5. Hold the handpiece (without an insert installed) over a sink
or drain. Activate the foot control and flush water through
handpiece for at least thirty seconds.
6. Place a sterilized insert into the handpiece.
9.3 Patient Comfort Considerations
Reasons for sensitivity
• Incorrect tip placement. Point should be directed away from
root surfaces.
• Allowing the insert to remain in a static position on the tooth.
Keep the tip in motion and change it's path on the tooth.
• Applying pressure. Use extremely light grasp and pressure,
especially on exposed cementum.
• If sensitivity persists, decrease power setting and/or move from
the sensitive tooth to another and then return.
